warren distribution, is NOT the smae as Warren oils. i read this on a post here. they are in act, not related. so havoline is not really manugfactured from Warren oil, another distributor, not realted, is the maker.
ziggy, you are correct.
Warren Performance Products, WPP, is the supplier of WalMart oils.
The other Warren is the one I don't pay too much attention to.
Confusing, eh? Good thing there isn't a second Pennzoil, Shell, Castrol, etc...
