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.
