UOA? VOA? Group I? II? III?

[Hubjeep]

I see these terms often on this site. What do they mean.

From reading the UOA and VOA seem to be some sort of tests. And the groups define the base of the oil?

A "FAQ" sticky thread on the top of the forum including basic information could help new members.

Thanks,
John
