Interesting link w/semi/full syn oil data by maker

Some good data - especially the explanations of certain specs and time lines for them.

Interesting, though it doesn't differentiate between oils that claim to meet certain specs and ones that actually carry the approvals. That's a big shortcoming IMO.

Seems to be missing a lot of oils, no Delvac, no Valvoline diesel oils at all, lots of things not in there
