So, this Home Depot in No. Va. (I'm not saying where, or Dick in Falls Church will beat me to it!) is moving to a new store down the street. They have some oil on clearance. MaxLife 5W30 and 10W30 in SL for 1.19/qt. They have a LOT of it. They have PP in 10W30 full syn, SL, 1.58/Qt (already grabbed the 14 qt they had of that.. They have Quaker State in 10W30SL, .99/qt. Pennzoil 5W30, and 10W30 in SL rating, .79/qt. All this stuff is old dusty stock (probably the best kind?). So, if I grab all the MaxLife SL-rated oil, most of it 5W30 and 10W30, what do you do with it in a car spec'd for 5W20? Mix it with 0W20 M1? SL MaxLife is LOADED with additives, right? Dunno about SL QS and Pennzoil. But, at these prices, shouldn't I be building a stash and worry about the blending later? Oooor, just go ahead and use the stuff, spec-be-damned?
