I'm less afraid of the store brands than I once was, but agree with O2zx9r that there are plenty of good sales out there on demonstrably better name brands, if one exerts the effort to find them. Just got my annual supply of Castrol GTX for $2.24 and Syntec for $3.99 at Meijer (I blend them). I see other good brands at good prices too... Castrol just gives me more of the warm fuzzies for my gassers from our long association. That said, I'm at the point where I don't automatically discount a store brand. Too many good UOAs and good user feedback for that.
