Where can I learn about Group I/II/III oils

[va3ux]

I see frequent reference to oils with "G II" or "G III" base oils. Can someone point me to where I can learn about these.

Thanks...Phil

I suggest the Chevron Base Oils Site .

Browse thru the FAQ's and the technical articles section - lots of info regarding base oil groups.
