Walmart is by far the best place to buy my oil and filters, especially for the prices ! If you don't need the supplies right away, shop for that great deal that will take a few days to get and the price is a heck of a lot better. I will definitely buy again.

Great oil at a great price

I feed this to my 1993 E-350 bus with the 7.3 IDI. The old girl loves it, and even helps on the cold starts. Cant beat the Sams price either....
