They are both quality products when it comes time to buy more oil the one with the cheaper price gets the wink. Right now its Mobil at $22.88.
At a second glance its Castrol GTX MAGNATEC 5W-30 Full Synthetic Motor Oil, 5 QT $19.88.
Well they just keep popping up this morning.
Havoline ProDS Synthetic Motor Oil 10W30 $16.73 I'd run that in a heart beat in my Toyota for summer oil.
Wonder if Havoline has a rebate on that?
