To me, Valvoline oils are as good as they "need to be". There are levels or tiers. Amsoil and M1 AP are over-engineered for a reason.

What reason is that?

Longer drain claims.

Supertech is selling an engine oil good for 20,000 mile oci. Advanced full synthetic 0W20. I guess it even more over engineered?

Claims are not real things.
