Point of re-clarification: Not all Havoline dino is produced by Chevron. Although the bottles look identical, on the back it will identify the ChevronTexaco Global Lubricants out of CA., or list Equilon out of Tx. If I recall correctly, the Equilon version is produced by Shell for now, and is not likely to be the same additive package as the Chevron. The majority consensus to date here has been to go with the Chevron version -- the Shell formulation seems to be unknown at this point.
