Hi Guys,

I was with Castrol India technical Sales team for over 18 years and have the Equivalent handbook. I exited 3 years ago and have now moved to Cumputer Education Industry. If you want to know specific info/equivalents, including GOST or Aviation specs I can email it to you. Pls send queries at hussam_adeni@yahoo.com.

Pls note I have moved to the IT industry and in my sparetime I can surely help out co-tribologists.

In Europe almost every oil company keeps record of an equivalent list. Besides that, there are always cases where different companies buy the same base oils and additive packages resulting in pure equivalents (especially in smaller countries with one ore two 'blenders'). There are a lot of equivalent lists available, in OEM specification as well as in oilcompany related products.
Oil equivalents, a risky route, particularly with engine oils, ATFs constantly changing to meet the most recents specs and approvals. How recent is the data Sheet?
I too have used the ZF lists and found the content very useful.(approved lubricants by application)
Major oil companies have data bases with all this type of info. available to consumers Auto ,industrial and off highway through help desks.
A lot of this info, recommended oils by OEM (Original Equipment Manufacturer), is provided for the oil companies by a UK based Co.OATS Ltd, see their web site.
There are literally hundreds of brands in the world, and variations on what is made by each depending on the country.
Some oils are group II in one country and group I in another. Specs are all over the place.
The chart is only a starting place. From there I would suggest getting the actual spec sheets from the products you are considering or other brands and comparing them.
A good lube supplier will do this for you.
A lot depends on the application. Despite the protestations of a certain advertizement a few years back, motor oil is pretty much motor oil.

Lubes are a bit of an odd duck in the business world, where things tend to fall into two categories - commodities & specialty products. Some lubes are commodities, like passenger car engine oil and AW hydraulic oil. These are high-volume products that are extensively defined by various industry standards. Some lubes are specialty products, like paper machine oils and polyurea greases.

Generally, automotive lubes are more likely to be commodities and industrials are more likely to be specialty products. (Hydraulic oils are the glaring exception here.)

Yes, OATS is one of few OEM data suppliers. For reliable and more detailed global OEM information also see Olyslager, which is globally the most accepted standard. This company published their first recommendation lists in the 60's.
