OIL, Where to buy in Phoenix?

[Lathe Guy]

I live in the Ahwatukee area and my shop is just south of the airport. Can anybody tell me a good place to buy motor oil? The Walmart near us has no selection at all . I haven't checked at any auto parts stores yet, but I know someone can point me in the right direction.

Thanks!!

Delo 400 is available at most Costco stores. Price is about $35 for 6 gal.
