Does anybody know of a comprehensive oil equivilents chart that covers a wide range of oil types? I believe that Castrol used to produce something similar but I am yet to find it.

Castrol still has an oil equivalent chart but they keep it pretty close to there chest. Only Castrol sales reps have it I'm led to believe. If you push them hard enough they may just give it up.

I have a chart that can help you, but it is in spanish, since I live in Costa Rica. Can you give me a email address to send it?

lubecr. My email is michaelabcross@bigpond.com. If you could send it to me I would very much appreciate it. Thank you in advance.

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.

Another tip: ZF approval lists (or other OEM's). This also will help finding equivalents. But always check the MSDS for compatibility.

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.

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 excepted standard. This company published their first recommendation lists in the 60's.
Some examples of this data (branded):

See if this helps any. It's from Plant Engineering magazine. http://www.plantengineering.com/contents/pdf/ple2004lubechart.PDF

Nice one, that's a keeper ;-)

Michael,

Many thanks for this handy reference.

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.
