Hughesy's Tech Tip - Viscosity Specification and Application Penrite Blog Post

Posted on 02 Mar 2017


Many people are confused when looking for an engine oil for their vehicle. There is Viscosity, API, ACEA, ILSAC, JASO, OEM Approved etc.

When looking at engine oils it is important to separate Viscosity, Specifications and Applications. Although several oils might have the same viscosity, that does not mean that they are suitable for the same applications. When selecting an engine oil, the right application needs to be met by the right specifications. A good example of this is with multiple types of low viscosity 5W-30 engine oils.

Let’s look at some Penrite examples –

As shown in the table, all of the oils are 5W-30 in viscosity but that is the only common point amongst them. Some are premium mineral, some semi synthetic and others full synthetic. Some have different API specifications, some have different ACEA specifications and some are OEM approved.

It is important when selecting an oil, to find the correct specifications to match the intended application and not just the viscosity. Generally the owners handbook will give –

1)     Preferred Viscosity or a range to work in depending on the climate of the country.

2)     API, ILSAC or ACEA or multiple specifications

3)     OEM (Original Equipment Manufacturer) specification

So picking the correct viscosity is only part of the selection process. Some oils are suitable for both petrol & diesel engines, some are suitable for petrol only. Each of the above oils, have chemical alterations from one another designed to cover different applications requested by manufacturers.

Further details on these products are available on their respective product information sheets found on the Penrite web site: www.penriteoil.com.au/
