No more regular oil at WalMart

I went to WalMart yesterday to get oil for the Pinzgauer and found out that they only sell synthetic oil now in 10w-30 and most other viscosities. I ended up going to AutoZone and paying $31 for a 5-quart jug of 10w-30.
I also wanted a Mobil1 oil filter and cannot find the correct part number that will work on the Pinz, even after trying to cross reference the Wix 51768 filter online. I ended up with an STP S5618 filter that worked fine.
I would have gone to NAPA but am tired of wanting to buy basic parts, only to be told that we can have it later today or tomorrow.

That's odd. I'm used to seeing tons of the typical Castrol and QT there. I recently paid that same amount or slightly less for a jug of Mobile1 synth. that her car gets.
