Default Group I-V

So I just read the sticky called oil basics part 1. It talks about oils being a group I, II, III, IV, or V. But how do I find out which brand oil is what group?

Motul, clicked on your link re the Twin Line oil but it's not listed. Have you more info on it?

I am currently using the 7100 20/50 synthetic.

Oils that use general terms like "Synthetic" or some variation like "Syn" are almost certainly using a Group 3 or lower base.

Let me know if you have any other questions as there is a ton more we could dive into with regards to quality of base oils, additives, etc.

What this means is Harley Davidson SYN 3 is not a full synthetic oil. It's base stock is hydrocracked oil from the ground; they get away with calling it a fully synthetic oil because of a lawsuit involving Castrol.

I have been using conventional, but was considering switching to synthetic. I have been looking at Lucas, Mobil 1, and Amsoil. What fluids do you use in your motor, primary, and transmission?
