The following website will show you the base oil group of many different specific oils, atfs etc.
I've seen Havoline, Valvoline, Citgo and more in there. Full synthetic is distinguished from Group III. I even saw a MB229.5 approved oil that is semi syn.
Post anything interesting that you find.

I think the cool thing is being able to filter by OEM Approval or OEM Spec to see what fluids meet your needs and what the base oil options are.
