High oil consumption could have a number of causes.
The most common tend to be:
1) Using too low a viscosity for the application
2) Viscosity breakdown
3) Using a low quality oil grade
4) Damaged or worn compression or oil rings
5) Damaged or worn valve stems and seals
6) Gasket and seal leaks
To slow oil consumption, a higher viscosity grade oil can be used, especially an oil with a higher operating temperature viscosity. Oil burns when at its hottest and therefore thinnest viscosity. By using an oil with a higher operating temperature viscosity, it will hold better film strength when at operating temperature making it less prone to being worked past worn engine rings or valve stems, seals and guides.

Some vehicle manufacturers have strict guidelines in relation to what approval specification the engine oil used in their vehicles must have. Lubricant manufacturers can supply approved products in order to maintain vehicle manufacturers warranties. Failure to use an OEM approved oil can therefore in some cases, void the manufacturers warranty.

Penrite holds many OEM approvals from major global automotive manufacturers, and these are being added too regularly. These OEM approvals are issued to Penrite to ensure that products, blended by Penrite, have met or exceeded their requirements as a warranty approved product.

Not using an OEM approved product, during the vehicles warranty period can be a risk! Even after the warranty period has expired using Penrite OEM Approved Engine Oils will help to maintain engine performance over the life of the vehicle.

Copies of the OEM Approvals can be found under the Products Tab on the Penrite Web Site. Click here to learn more.

Zinc or ZDDP (Dialkyl DithioPhosphate), is a chemical compound used in engine oil as a sacrificial and very effective anti-wear agent.

ZInc works under heat and load. The Zinc reacts with the steel surface and creates a phosphate glass film that protects the steel surface by forming a sacrificial film that covers the peaks and fills in the valleys of the steel surface. This helps to protect highly loaded engine parts.

There is a lot of hysteria over zinc levels in oils, especially in the latest specification engine oils. Many of these myths and stories are unfounded. To understand more about ZINC and its purpose in engine oil Click Here to read the latest up to date information about ZInc in engine oils.

Petrol engine oils can be used in diesel engines if the oil meets the minimum requirements specified by the manufacturer for that particular engine.

For example, if the manufacturer specifies API CF or later specification as being suitable for the engine, then as long as the engine oil meets API CF or higher specifications (ie CF-2, CF-4, CG-4, CG-4, CH-4, CI-4, CI-4 Plus) then there is no issue. Obviously the later the specification, the better it will be for the engine.

Mineral, Semi Synthetic and Synthetic oils can be mixed together, although this is not recommended.

During the blending process, various and different additive packs are added to base oil to achieve various oil specifications for different intended applications. (eg Petrol or Diesel type oil). Therefore, a combination of different oils will almost certainly have been created to cover different applications and may not always be compatible with one another. Mixing different types and viscosities of oils changes the original chemistry balance of the oil and may result in an unsuitable product for certain types of applications. So although the base oils will mix quite readily, the additive packs used in them are designed for particular applications and a combination of these is an unknown concoction in terms of performance and compatibility.

In certain circumstances, putting the wrong oil into an engine can cause extensive damage to the engine or components associated with it. It is always best to use the same type, viscosity and manufacturer specification when topping up your engine oil.

No it isn't. and conversely, there is nothing stopping you moving from Mineral to Semi Synthetic to Full Synthetic engine oils.

An engine may take a little while to settle down if oil type is changed (which is sometimes the case going from brand-to-brand or grade-to-grade), but after that, there shouldn't be any problems.

It is more important to find the "Right oil for the right Application" than the base oil type.

Over time and after operating in internally in an internal combustion engine, oil will deteriorate and become less efficient at providing good lubrication and protection for the engine.
The main reasons to change your engine oil are as follows -

1. To remove contaminants that degrade the oil. i.e.
a) Moisture (condensation)
b) Un-burnt fuel (ie fuel dilution)
c) Soot (by product of combustion, especially in diesels)
d) Oxidation and Nitration By-products such as acids

2. To refresh the oil as additives in the oil deteriorate over time. i.e
a) Detergents, that help keep the engine clean become less effective
b) Dispersants, that hold contaminants in the oil become saturated and can no longer retain contaminants.
c) Anti-wear additives need to be replaced such as ZINC which is sacrificial.
d) VI Improvers are sheared by the engine and hence oil loses its viscosity lowering operating protection protection

The cheapest thing most people will ever do to keep their vehicle going will be to change the oil and filter regularly.

Most vehicle manufacturers have a recommended service period either based on kilometres travelled or a specified time period. To maintain the vehicles engine in good condition, owners should not exceed these specified service periods.

The use of high quality engine oil such as Penrite, will provide protection for the engine throughout the whole service period. We do not recommend exceeding the manufacturer's service intervals. Your owners hand book will contain the vehicles recommended servicing periods. These can vary by manufacturer, engine type and conditions in which the vehicle is used.

To ensure you select the correct grade and specification of oil for your vehicle, look up your vehicle on the Penrite Recommendation Guide Click here to look up your vehicle.

Multigrade oils must meet both a "W" low temperature (Cold Cranking) viscosity requirement and a 100°C "operating temperature" requirement. A multigrade oil gives you the best of both worlds by maintaining its performance at high and low temperatures. All liquids thin out as heat increases but a multigrade keeps viscosity at optimum levels within a certain temperature range. (eg. 10W-40)

Monograde oils do not have a low temperature requirement. Therefore, as the temperature decreases, they thicken considerably faster than equivalent multigrade oils. As temperature increases they thin out evenly across a temperature range (e.g. SAE 30). Monograde engine oils do not suffer from shear as there is viscosity index improvers in the oil.

To find out what oil to use in your vehicle, you will need to know the following
1) Make of Vehicle
2) Year of Manufacture
3) Model Type
3) Engine Type and SIze
4) Transmission Type (this is needed for some vehicles)
Most of these are all available from your owner's handbook.

2) Select your make
3) Select your model

The Penrite recommendation guide will not only advise you of the correct oil, but will also recommend all of your lubricant needs for your vehicle based on the vehicle manufacturer's specifications.

Some vehicles require an OEM (Original Equipment Manufacturer) approved oil. Failure to use the correct oil can result in the vehicle's warranty being void.
We always recommend using our recommendation guide either in store or on the web.

If your vehicle is powered by LPG (Liquid Petroleum Gas) or is dual fuel (Petrol/LPG), Penrite has a range of products suitable for your vehicle. Running a vehicle on LPG can bring a significant cost saving over running a vehicle on petrol, but ensuring you utilise the correct oil is imperative.

The main reason why you need to use a specialised gas oil is due to oil nitration. Oil nitration is an undesirable condition which indicates that the oil is becoming saturated with the soluble and/or insoluble nitrogen oxide compounds.Oil nitration is the main cause of bearing wear, piston deposits and the formation of sludge in LPG powered vehicles. This can happen particularly when the oil is run past its drain period, by using poor quality oil, by using poor quality fuels or using the incorrect oil specification. In these cases the oil can become nitrated by the gas and begin to cause bearing failure.
Ordinary petrol oils do not cater for these effects, therefore using specialised LPG oil can save on expensive repair bills.

Penrite HPR Gas and HPR Gas 10 have effective additives that counter balance the effects of running your vehicle on LPG.

If your LPG was fitted at an after market service centre and you are not quite sure of which oil best suits your vehicle, please call our Technical Support deptartment on
1300 PENRITE (1300 736 748) so as we can advise you on the correct oil for your vehicle.

Most Penrite oils contain additives that improve the performance of the engine oil. These additives, amongst other important ingredients, contain detergents and dispersants.

Detergents are an extremely important part of the engine oil and are incorporated into the oil blend to keep the internals of your engine clean, whilst dispersants are added to suspend the contaminants that are too fine for the filter to capture and these are then flushed away during an oil change. Modern day engine oils require carefully selected additives to perform these tasks and not become saturated during the extended oil drain interval. Late specifications such as API SN and ACEA A3/B4 grade oils provide the highest levels of detergency to keep engines cleaner for longer. This stops the build up of sludge, piston deposits and reduces wear significantly over their previous grades. To see how much better these oils perform Click Here to see the results.

Penrite oils are specifically developed to keep cleaning and looking after your engine for the entire service period. To keep your engine clean, you should change your oil and oil filter regularly.

"SAPS" stands for "Sulphated Ash, Phosphorous and Sulphur".

A "LOW SAPS" engine oil has a lesser amount of these elements than a standard engine oil. The levels vary depending on the type of oil needed.

LOW SAPS oils are generally used in modern turbo diesel engines that are fitted a Diesel Particulate Filter (DPF) or in modern petrol engines to assist in fuel economy gains.

Penrite Enviro+ engine oils were developed and introduced for vehicles that require Low SAPS oils. To visit the Penrite Enviro+ web page Click Here

Penrite does produce oils suitable for vehicles fitted with a DPF (Diesel Particulate Filter).

Modern turbo diesel vehicles are increasingly being fitted with DPF's to assist in reducing engine emissions and they require specific oil compatible with these units. The Penrite Enviro+ range of engine oils cover the majority of diesel passenger cars available in the market today that are fitted with a DPF.
The Penrite Enviro Plus range of engine oils also hold OEM (Original Equipment Manufacturers) approvals so these oils can be used in your new vehicles without effecting your manufacturer's warranty.

At Penrite we like to lead the market with new technologies and better products for our customers. Our vision is a cleaner future and protecting the environment from unnecessary pollutants that are caused by today's transport needs. Modern vehicle manufacturers are also introducing technology into their products that can lower the effects of environmental damage caused by pollutants produced by modern day transport. Some of the manufacturer introduced technology such as diesel particulate filters necessitated the need for fuels and lubricants to be both cleaner and carry less of the ingredients that were harmful to the environment.

Penrite were the first company in Australia to lead the lubricant manufacturers into the aftermarket with Low "SAPS" engine oils leading the way to a cater for vehicles that require these cleaner running oils. We also introduced newer and cleaner technologies into our engine oils that will allowed them to become less harmful to the environment without sacrificing the ultimate protection for which we are renowned.

Hence why we called our cleaner running oils "Enviro+". Not only do they care for the environment, but also for your engine!

The Penrite10/Tenths Racing oils range uses a unique "Shear Free" formulation. This ensures that the oil will hold its viscosity for the life of the oil even under the most arduous of treatment on the road or on the racetrack.

Most engine oils contain viscosity index (V.I.) Improvers to slow down the oil thinning process. Oil thinning is caused through heat in an internal combustion engine. Viscosity Index Improvers expand as they heat allowing the oil to become multi-grade instead of mono grade. These V.I. Improvers are sheared by the engines internal movements causing the oil to lose some of its effective viscosity lowering its performance to protect the engine. Penrite's range of 10/Tenths Racing oils do not contain viscosity index improvers as normally found in most multi-grade engine oils so therefore cannot be sheared and therefore will provide better protection for the life of the oil.
No other oil on the market has this unique feature!

Oil change

Changing your oil is one of the most important things you’ll ever do for your engine. Going DIY not only saves dollars, it’s also very satisfying if you enjoy getting a little grease under your fingernails. And it’s actually a lot easier than you think with our safe step-by-step guide.


What’s the big deal about changing my oil?

Like anything, motor oil has a limited shelf life and starts to break down after a period of use, making it less efficient in lubricating and cooling engine parts.

There are two key reasons for this. Firstly, the additives that protect your engine against corrosion, oxidisation and engine wear get used up as they do their job. And secondly, contaminants like soot, carbon and acids build up and start to affect the critical properties of your oil, such as viscosity.


How often should I change my oil?

Oil that’s not changed regularly can do serious damage to your engine and compromise the safety of your vehicle. This is why manufacturers recommend that you change your oil regularly – either after a specified period of time or after a certain distance. Most owner manuals have two recommendations for oil changes – standard and severe – which are based on the kind of conditions you drive in.


Your step-by-step guide to changing oil

The first thing to do is get together everything you need to get the job done safely and well. Here’s a checklist:

Approximately 5 litres of Penrite motor oil
Check your owner's manual for correct SAE viscosity, API or ACEA performance and quantity.

A drop sheet

A new oil filter
Again your owner's manual will tell you the type and size you need.

A drain plug socket wrench or open-end wrench (exact size) and an oil filter wrench.

A large drain pan, at least double the size of your sump.

A rag, hand cleaning solution and/or disposable latex gloves.

A funnel


Step 1 - Choose Your Oil

Your owner's manual will give you information on what kind of oil you need for both normal and severe driving conditions. It might surprise you to know that a lot of driving actually falls into the severe category. Extreme temperatures, frequent short trips, stop-start traffic and hauling or towing all put extra strain on your engine and mean you need an oil that is suitable for severe driving conditions, as well as more regular oil changes.

A good guide is to change your motor oil and oil filter every 5,000 kilometres or every six months, whichever comes first. Doing this will give better engine protection and prolong your engine’s life. Make sure you check your owner's manual for special conditions and do not exceed warranty recommendations.

Need some expert advice? Call Penrite’s Technical Services Helpline during business hours on 1800 110 080.


Step 2 - Prepare safely

Always put your safety first. Before you even think about getting under your vehicle, read the safety information in your manual. Choose level ground and start by laying a drop sheet to avoid permanent staining.

Unless you want to risk looking like road kill, never use a jack to support your vehicle. Wheel ramps are much more stable and will tilt the car just enough to allow you to slide underneath.
Drive your vehicle onto the wheel ramps so that the front tyres are raised, apply the emergency brake and chock the rear wheels to prevent rolling.

Put your vehicle in first gear if you have a manual transmission or park if you have an automatic transmission and you’re good to go.


Step 3 - Drain the old oil

Warm oil drains much more quickly, so run your engine for about 5 to10 minutes to bring it to normal operating temperature. Then turn off the engine and wait till it’s cool. Open the hood and loosen the oil sump cap to allow the oil to drain from the bottom more freely.
Find the oil drain plug and put the drain pan underneath it. Using a wrench, turn the plug anti-clockwise until it rotates freely. Remove the plug CAREFULLY to avoid burning yourself as the oil may still be very hot.


Step 4 - Remove the Oil Filter

Next, loosen the oil filter by turning it anti-clockwise using a filter wrench. Carefully ease it away from the engine and tip the contents into the drain pan.


Step 5 - Replace the oil filter

Using a rag, wipe in and around the filter seal on the engine. Take a new filter and apply a light film of oil (new or used) to the circular edge of the filter itself (aka the gasket).

Fill the new filter with new engine oil and screw it onto the threaded oil line in a clockwise direction. Tighten the filter by hand.

Clean the oil plug and drain set and if necessary replace the plug basket or seal. Screw the plug in by hand and finish by tightening it with a wrench, but don’t overtighten.


Step 6 - Add clean oil

Unscrew the cap on top of your engine (the one that says “Oil”!) and fill her up with the recommended amount of oil, checking the level with the dipstick. Replace the cap and wipe off excess oil.

Now it’s time to test your handiwork. The oil light should go out as soon as the engine is switched on.

Motor oils are made up of two main ingredients: BASE STOCKS (Mineral or synthetic) or a mixture of the two (Semi Synthetic) and ADDITIVES.

Base Stocks
Mineral base stocks are made from naturally occurring crude oil pumped from the earth and processed in an oil refinery.

Synthetic base stocks are developed in a lab. They are produced from extremely pure chemicals and are engineered with specific characteristics to cater for many different applications e.g. better performance in extreme temperatures.

Additives are what you might call the active ingredients in motor oil. Combined with base stocks they provide all sorts of functions, from cleaning and cooling your engine to preventing rust and protecting against extreme pressure.

A bit like the nutrients in soil, these additives need to be replenished regularly, which is one of the reasons why oil changes are so important for your engine.

Motor oil serves many purposes in an engine. Its main job is to stop wear and friction in your engine. These are caused when the various metal engine parts of the engine, grind together causing heat, friction and then wear.

As motor oil flows around your engine it coats and lubricates the metal surfaces acting as a barrier or film, stopping the metal parts from actually touching each other, thus reducing friction and wear as well as dispersing the heat generated during the process.

Motor oil also helps to keep your engine clean and free from build-ups by using intelligent detergents and dispersants that clean and hold in suspension the by products of combustion (like silica and acids) that are not caught by the oil filter. These contaminants are removed during the oil change process. Oil also disperses layers of extra protection such as Zinc, which acts as sacrificial agent between metal parts improving wear protection, especially in older push rod type engines.

Apart from protecting the engine, motor oil reduces rust and corrosion by limiting your engine’s exposure to oxygen.

Additives are what you might call the active ingredients your motor oil. Combined with base stocks they provide all sorts of functions, from cleaning and cooling your engine to preventing rust and protecting against extreme pressure.

A bit like the nutrients in soil, these additives need to be replenished regularly – which is one of the reasons why oil changes are so important for your engine.

The additives used in engine oils will vary considerably between different types of oils and there applications.

Some of the main additives used are -

  • Detergents - Which help keep the engine clean and neutralise acids that form from the combustion process
  • Dispersants - These encapsulate matter that is too small to be filtered and hold it in suspension until an oil change is performed
  • VI Improvers - These are elastomers that expand when heated which provides for multi-grade viscosities
  • Anti-Wear - Generally these are products like ZINC that provides a sacrificial barrier between moving parts
  • Ant-Oxidants - These stop or neutralise the internals of the engine from corroding
  • Anti-Foam - This stops the oil from foaming especially as it contains detergents
  • Pour Point Depressants - These help oil pour at low temperatures
  • Of course, the amounts of additives will vary between engine oil types and specifications.

    All these oils now offer significant levels of protection for both new and older engines. Choice of oil type can sometimes be a personal preference of the user or dictated by the engine or vehicle manufacturer.

    Full Synthetic oils can be engineered for many different applications. One of the benefits of synthetics is the quality and purity of the base oil. They contain less impurities than mineral based oils such lower sulfur and wax levels, as well as less hydrocarbons. Synthetic base oils give outstanding performance especially as lower viscosity oils. They naturally have a higher viscosity index which stops them from becoming too thick when cold and too thin when at operating temperature. Hence these oils flow more easily on start up providing engine protection when it most often occurs. They are much less volatile than mineral base oils meaning they are more stable at temperature, burn less and require less additives that can be the cause of engine deposits. They are also less prone to oxidation providing better anti corrosion protection for the engine. The latest specification Full Synthetic Engine oils can offer up to three times more protection, five times better cleansing and less than half as much engine wear compared with oils 20 years ago.

    Semi Synthetic oils are a blend of synthetic and mineral base oils. Generally to be classed as semi synthetic at Penrite, they need to be at least 20% or more Full Synthetic oil. Other names such as "Synthetic Fortified" or "Synthetic Blend" are also used for these oils. The levels of Full Synthetic base oil will vary considerably between different brands and specifications. Semi Synthetic engine oils provide the good points of both mineral (cost) and synthetic (performance) oils and can be engineered to offer excellent protection, cleanliness performance, generally at a lower cost than Full Synthetic oils.

    Mineral or conventional engine oils are derived from naturally occurring deposits and are refined by different methods to produce base oils. There are many levels of mineral base oils from low to outstanding quality. The use defined by the application. Generally, the more the product is refined, the more pure the base stock. The more pure the base stock, the better the performance as an engine oil. Good quality mineral base oils can offer nearly all the same specifications as the more expensive synthetic types especially if mixed with high performance additive packs. They are extremely popular in the manufacture of older specification, higher viscosity engine oils but can also be used to manufacture low viscosity, fuel efficient and latest specification engine oils.

    A major performance advantage of synthetics is their ability to provide optimum lube at extreme temperatures. They remain stable at very high temperatures (when most conventional oils start to break down) and remain fluid at very low temperatures (when conventional oils start to thicken). This reduces wear and tear and helps to maintain a cleaner, more efficient engine.

    Synthetics also last longer because they break down more slowly than conventional oils – but remember, just like conventional oils, regular oil changes are essential to remove contaminants.

    If you can capitalise on the benefits – for example if you drive in extreme conditions or have a high performance car – synthetics can be the way to go. Although they’re more expensive, they can work out better value in the longer term. You might also consider a blend – a more cost-effective mix of synthetic and conventional oils.

    The bottom line is that each car is different and you need to consider a range of factors including manufacturer’s recommendations, climate conditions and, last but not least, affordability. That’s why we recommend using our Oil Selector to find the perfect oil fit for your car.

    FULL ZINC + is an anti wear additive package for ultimate engine wear protection containing optimum zinc levels, boron and organomolybdenum complex to lift the total level of anti wear package additives to over 1800+ ppm.

    SHEAR is the breaking down of oil molecules as a result of heat and load. As shear increases it inhibits the oils ability to protect against metal to metal contact with resultant wear, loss of oil pressure and engine power. Penrite's SHEAR free formulation offers start up protection, maintains oil pressure and eliminates viscosity loss for ultimate performance.

    All Penrite oils are manufactured as a balanced blend of base oils and additives designed to fit particular applications.

    If one of our oils needs a specific additive for a particular application, it will already be added in to that particular oils additive pack in the correct dosage.

    By adding in extra ingredients to an engine oil, you are upsetting the carefully balanced blend of base oil and additives that are already in the oil. This physically alters the engine oils ingredients and therefore chemically upsets the balance of that particular oil. An additive could also attack or not be compatible with the additives already in the oil, which may in turn cause more damage than good within the engine. Once the chemical balance of the oil is tampered with, it also wipes any warranty with that particular oil. So unless an additive is approved for use with a particular oil, we don't suggest adding anything to our engine oils.

    Dexos® is General Motors Corporation international standard for engine oils suitable for use in their ranges of fuel efficient, low emission engines.
    Dexos® 1 is for petrol driven engines meeting ILSAC GF-5 Resource Conserving specifications.
    Dexos® 2 is for Diesel and some petrol driven vehicles and meets Low SAP requirements for vehicles fitted with exhaust treatment devices such as DPFs (Diesel Particulate Filters).

    Our products have quality LSD additives that make them suitable for both hypoid and limited slip applications. Penrite Gear Oils minimize the risk of misapplication and reduce inventory by not having to range separate Hypoid and LSD type oils.

    Limited Slip Differentials (LSD) need a friction modifier additive in the gear oil to prevent the clutch packs from chattering. Penrite Gear Oils and selected Pro Gear products already have the correct dosage of LSD additive in the oil.

    GL is short for "GEAR LUBRICANT"

    GL-5 gear oils have a higher ratio of extreme pressure additives than GL-4 gear oils. GL-5 products can be used where GL-4 products are recommended but GL-4 products can not be used where GL-5 is specified. GL-5 rated oil is required for most differentials due to the extreme pressure generated by the crown and pinion drive system, whereas most manual transmissions only require a GL-4 rated product.

    A Transaxle is a transmission (gearbox) and differential combined as used in most front wheel drive vehicles.

    A Transfer Case is a gearbox that distributes drive between the front and rear wheels of a 4WD vehicle.

    Yes, this is quite normal for manufacturers to use ATF's in manual transmissions. Depending on the transmission type, Penrite have products that may be able to replace the ATF fluid such as Pro Gear 70W-75, whilst providing better shift quality and longer fluid life.

    No. Penrite Pro Gear GL-5 75W-85 is an API GL-5 designed for differentials and extreme pressure applications. Penrite Pro Gear 75W-85 is an API GL-4 and is designed for transmissions and transaxles.

    Penrite oils have been used in competition and racing for many years and have an outstanding reputation amongst competitors for providing products that protect and perform in the most extreme conditions.

    There are some manufacturers that make this claim. Like all lubricants, over time, gear oils degrade from constant use. When degradation occurs, the fluid will not perform at its optimum level, affecting the performance of the vehicle. Therefore, we recommend that these fluids be changed at regular intervals during the lifespan of the vehicle.

    No, we do not. Our coolants are either Type A or Type B and require dilution with water, unless a premix version is used, in which case, no further dilution is necessary.

    Type A coolants contain inhibitors to protect the cooling system from rust, corrosion & cavitation as well as an effective Anti-Freeze/Anti Boil solution normally present as a type of glycol. Therefore Type A coolants will keep your cooling system from rusting and deteriorating as well as providing a lower freezing and a higher boiling temperature.

    Type B coolants contain only inhibitors for rust, corrosion & cavitation. They DO NOT contain any Anti-Freeze/Anti-Boil emulsions. Type B coolants will keep your cooling system from rusting and deteriorating. If the Type B contains an effective anti-cavitation agent, then this can assist the cooling system to operate more effectively.

    All colours in coolants are dyes used by the manufacturers to distinguish different products. In Australia, Red/Pink/Magenta coloured coolants are generally contain an OAT inhibitor pack and Green/Blue/Yellow generally contain Hybrid inhibitor packs. Overall, a coolant can be any colour that a manufacturer wants to make it.

    Yes - Penrite have 7 Year 450,000km Blue Coolant in concentrate and premix. It is OEM approved and is suitable for use with Australian, European, Asian & US vehicles. It is Silicate, Borate and Phosphate Free making it particularly suitable for both European & Japanese vehicles that use blue coloured coolant such as Nissan, Subaru & Suzuki.

    Different types of coolants have different types of additive packs in them to stop corrosion, rust, scaling etc.
    Some of these additive technologies aren't compatible with others and can cause a chemical reaction that can cause major damage to the cooling system and ancillary parts.

    Penrite have a Universal Top Up coolant that has unique chemistry and can be mixed with all types of Anti Freeze Anti Boil Coolants.

    Penrite Universal Coolant Top Up is a special blend product designed to mix with all coolant types that -
    1. Does not degrade the original coolant
    2. Will not discolour the original coolant if used at under 10% volume
    It is ideal as an emergency top up for someone who does not know what type of coolant is in their vehicle.

    Yes, if the vehicle travels in conditions where it is not below freezing point.

    If the tap water is of high quality, then it is safe to mix with concentrate although this can vary considerably be region. Tank water should not be used to mix coolant because it may contain a high degree of minerals which could cause a reaction internally. When in doubt, premix is always the safest option unless mixing with pure de-mineralised water.

    Refer to the Penrite Lubrication guide, the owner's handbook or factory service manual.

    A radiator flush should be used to neutralise any left over coolant in the system prior to refilling the system with new coolant. This reduces the risk of the new coolant reacting with the old coolant and generally gives the system a good clean out at the same time improving performance of the cooling system.

    These are the types of inhibitor packs used in coolants.
    Hybrid or 'HOAT' stands for Hybrid Organic Acid Technology. Hybrid formulations are called Hybrid because they contain ingredients from both OAT and conventional Hybrid formulas and are compatible with both.
    OAT formulations are not normally compatible with conventional antifreezes. OAT antifreeze reacts to some extent with some of the inorganic salts and caustics used in conventional antifreeze.

    NO! A DOT 5 brake fluid is silicone based whereas a DOT 5.1 brake fluid is glycol ether based. They will not mix.

    Like, oils and lubricants, different vehicles call for different types of fluids. Like engine oils, ATF's, gear oils & coolants - Right Product, Right Application.

    DOT 4 ESP is optimised for faster reaction times than other fluids. This is essential for on board electronic systems such as ESP (Electronic Stability Programs), ABS (Anti-Skid Braking) and Vehicle Collision avoidance systems to work at peak performance. It can replace SUPER DOT 4/DOT 4 and DOT 3 Fluids.
    DOT 5.1 is a low viscosity fluid designed to work with Micro Valved ABS systems and also to circulate at extremely cold temperatures.
    Super DOT 4, DOT 4 and DOT 3 are non petroleum, synthetic brake fluids designed for use in a wide range of brake and clutch applications.

    No - DOT 4 ESP and DOT 5.1 are specified by vehicle manufacturers for specific types of vehicles that have systems suited to their properties. Although they can be used to replace DOT 3 and DOT 4 fluids in other vehicles, DOT 3 and DOT 4 fluid continue to be the mainstream fluids used by manufacturers.

    The main difference is the viscosity as well as the dry and wet boiling points of the fluids. Dry boiling points as follows -
    DOT 3=240°C
    SUPER DOT 4=275°C

    There is no reason why this cannot be done in most vehicles. Before using Silicone Brake Fluid - The old fluid needs to flushed completely out of the system, including calipers, lines, master cylinders, ABS modules and all parts of the system before the new fluid can be used.
    This is essential as DOT 5 Silicone Brake fluid is not compatible with any other type of brake fluid.

    NO - definitely not. DOT 5 Silicone Brake Fluid incompatible with other brake fluids and mixing could cause a serious brake failure.

    DOT 3, SUPER DOT4, DOT 4 ESP, DOT 5.1, RACING BRAKE FLUID and DOT 5.0 SILICONE brake fluids are all non petroleum, synthetic fluids. The only mineral brake fluid available is LHM Plus, which is used in some vehicles including selected Rolls Royce and Jaguar systems. See Penrite Power Steering & Suspension Fluid flyer for more information on LHM Plus.

    All Brake fluids apart from Silicone Brake fluid are Hygroscopic and will absorb water over time. Therefore, they all have a limited life span. Generally, the higher the DOT number the less prone they are to absorbing water and hence the longer the fluid will last without needing changing.

    Water is compressible where as brake fluid is not. The more water in the fluid, the "spongier" the brake pedal. Water will boil off and vapourise at 100°C whereas, even DOT 3 brake fluids have a dry boiling point of > 205°C. This vapourising can cause a dramatic loss of braking performance.

    DOT 4 and DOT 3 fluids are compatible with each other as well as DOT 4 ESP, and DOT 5.1
    RACING BRAKE FLUID is compatible with Super DOT 4, DOT 4, DOT 4 ESP and DOT 5.1. It is NOT compatible with DOT 3 fluids
    DOT 5 SILICONE FLUID is NOT compatible with any other brake fluid

    Yes, Racing Brake Fluid is a Super Dot 4 Plus fluid and is perfectly suitable for most vehicles.

    OEM manufacturers have different specifications for their power steering systems that require the use of different types of fluids. Penrite have the right product for the right application.

    The Ford power steering system from EL - FG models requires a higher viscosity fluid than a standard Dexron® III type product. Ford have a specification for this - M2C134-C/D. Penrite Power Steering Fluid meets this specification.

    Power steering fluids are formulated with purpose designed additives for power steering systems that can provide better control of shuddering noise and squawk over the recommended ATF. Power steering fluids will also outlast ATFs in power steering systems, making them more economical and save on service costs.

    The ONLY mineral brake fluid is an LHM Fluid. It is only used as brake fluid in selected Jaguar and Rolls Royce vehicles. It should not be used or mixed with any other type of brake fluid.

    Although DEXRON® VI is specified in these power steering systems, PAS Fluid, being a purpose built power steering and suspension fluid, is also suitable for use in these applications where DEXRON® VI fluid is specified. Flush before refilling with PAS fluid.

    Many new vehicles have electrically driven pumps for their power steering systems and they may not require any type of fluid. You should always check this with your manufacturer, your mechanic or the Penrite Lube Guide.

    Penrite LHM PLus fluid replaces both LHM (Liquide Hydraulique Minéral) green fluid and the original red LHS fluid used by Citroen. LDAS can also be used if a synthetic alternative is required.

    Mini Hydrolastic suspension does not require normal suspension fluids. They use a mixture of 33% Anti-Freeze Ant-Boil Coolant mixed with de-mineralised water.

    Honda vehicles require their own power steering fluid because they use a heavier viscosity fluid compared to vehicles using a DEXRON® type product.

    Yes, LHMP is the equivalent of between a Fork Oil 5 and 10. It can also be used as a light hydraulic oil.

    Yes LDAS can be used to replace LHM Plus in most applications. There are 2 products to satisfy the manufacturers requests for either a mineral or synthetic based product. Many new vehicles ask for synthetic products and older vehicles ask for mineral based products where synthetic products may not be suitable, i.e. some Rolls Royce brake and suspension systems.

    Yes- Penrite manufacture a full range of engine oils as well as other lubricants such as fork oils, foam filter oils and gear box oil for all types of motor cycles.

    Penrite are partners with Team Penrite Honda who are the factory Honda Motor Cross and Super Cross team in Australia.
    Penrite oils are used exclusively in the Team Penrite Honda factory bikes and put through a torturing competition campaign in testing and race conditions to ensure the product on sale passes all expectations and provides our customers with the highest quality products for all conditions.
    The Penrite Honda team along with other sponsored and competition users provide us with constant feedback ensuring we stay on top of testing and improvements on our product ranges.

    Yes - Penrite has a large range of engine oils designed specifically for marine use.

    Both 2 Stroke and 4 Stroke oils are available in the Penrite range as well as diesel and petrol engine oils. We also have marine grease and gear oil. To visit the Marine Page please click on the following link -
    Penrite Marine Range

    No - Most of Penrite's marine oils carry NMMA registrations (approvals) which are shown on the web page for each product. Penrite have approvals for both 2 stroke (TCW-3) and four stroke engines (FC-W).

    These approvals are the equivalent of an OEM approval and are granted by the National Marine Manufacturers Association which is a board composed of the manufacturers of the original marine equipment (OEMs).

    When buying marine oils, you should be aware of the manufacturers requirements as using a non-approved four stroke or two stroke oils could jeopardise your engine warranty.

    To ensure the correct mix of oil to petrol in your Two Stroke engine refer to your owner's handbook. The correct ratio is paramount to ensuring longevity of your Two Stroke engine. Two Stroke engines are more prone to wear compared to four-stroke engines due to the lack of a dedicated lubrication system which means that the parts of a two-stroke engine wear a lot faster. So using the right oil and more importantly the correct ratio of oil to petrol is very important. To view a comprehensive mix ratio chart Click here

    Yes Penrite have a complete range of products available for vehicles dating back to the start of the last century.

    Products available are - Engine Oils, Gear Lubricants, Greases, Coolant and other miscellaneous products to keep these vehicles on the go. In fact, Penrite are the only company in Australia manufacturing a range of products for yester-years Veteran, Vintage, Classic and Edwardian vehicles.

    Penrite Oil Company is the oldest Australian family owned independent oil company in Australia. We boast two blending facilities in Australia. Our first blending facility, along with our Head Office is located in Wantirna, Victoria and our second blending facility is located in Crestmead, Queensland. These two state of the art modern production facilities blend the majority of our product range.
    In 2007 Penrite acquired its third blending facility in Bream, England bringing a truly international presence to the Penrite brand.
    Penrite's ongoing philosophy of producing the highest quality product for every application, since 1926, remains a core value of the company to this day.

    The "W" literally stands for Winter grade. In order for an oil to be classified a W grade, it must not exceed specific cold crank viscosity and pumpability tests at specific temperatures (e.g. to be classified as a 0W oil, must not exceed 6200cP at -35°C. Viscosity basically means the thickness of a liquid and how easily it flows. For example, water has a low viscosity compared with, say olive oil. A good quality lubricant maintains its viscosity under different temperature and usage conditions for a longer period of time. Choosing the right viscosity motor oil depends on the conditions your vehicle operates in, but a general rule is that the viscosity should be low enough to ensure that oil can flow to where it's needed, but heavy enough to lubricate and protect parts from heat and wear.

    The short answer is No, Penrite does not use any recycled oil in the manufacturing process. Rest assured that Penrite only uses newly refined base oils for all of its engine oils.

    Light Duty vehicles are those that are typically less than 3.5 gvw (Gross Vehicle Weight), whilst vehicles above 3.5gvw are considered Heavy Duty vehicles.

    Used oil, or 'sump oil' can be cleaned and re-used again and again. It can come back to life as industrial burner fuel or hydraulic oil or it can be re-refined back into new lubricating oil.

    These days most councils and shires have a local used oil collection facility where you can take smaller quantities of used oil for recycling. Some may also accept oily rags, oil filters and oil containers.

    If you run a small company, like a workshop or service station, then you may need to contact a used oil collector to come and remove your used oil. Many collectors will do this free of charge.

    For more information on recycling your used motor oil safely and responsibly, contact your local council or visit their website.

    The Australian Government website also has useful information about recycling used oil: http://www.oilrecycling.gov.au/
