The Equilon Havoline is probably almost like Shell. As stated above, the Chevron Havoline is probably better. Wal-Mart's house oil will probably soon be the same as the old Havoline.
There's been very little discussion or testing of Shell. I thought the mid-90's Consumer Reports stated that it varied widely in different parts of the country.
Advance Auto Parts house brand may be identical to the new (Chevron) Havoline.
