It looks like on Amazon right now for subscribe & save the oil is about $37, but there is a $6.00 coupon you can "click," so that brings it down to about $31 for 6 quarts, pretty good for a world class oil to your door with no rebate to hassle (if you only need 6 quarts). Maybe if your household has two amazon accounts, you could get two deals. Just remember to cancel the subscribe & save right away.
I'm so hesitant to leave Mobil 1 0w40 though. Looking at VOAs, it doesn't seem as rich. What does a product like Ultra use instead of Moly? The other numbers, for detergents and whatnot, are equal or slightly below Mobil 1 0w-40.
However, I know the NOACK is better with this latest Ultra.
Seems like a tough decision.
