AutoZone now carries the Mobil 1 ESP 0W-40 Dexos2 oil and some stores stock it or you can have it shipped. Click See Available Deals to get 10 quarts and an 2 STP filters for $77.98. I was able to return unwanted filters to make it an even better deal but that is not guaranteed. I prefer to use the ACDelco OEM filter.
