Bad Dino?

After reading the posts here, I am having a hard time finding any bad reviews on any SM GF4 rated dino oil. Does one exist?

Not when one utilizes reasonable OCI's. No.

No such thing as a 'bad' dino oil if its GF-4 SM rated.

what about an SM but not GF-4? e.g. a 15w-40 or 10w-40 weight oil.

Ilsac GF-4 put a strict limit on Phosphorous based additives, that is why some 10w40 and 15w40 oils don't pass the test.
