Jetronic said:Ironically, at our Walmarts here, their 20w-50 offering is actually cheaper per quart than other regularly priced conventionals from Valvoline, Shell, Castrol, Mobil, and so forth. Of course, Synpower or any other synthetic (or conventional) 5w30 would do the trick, but VR1 does have a certain attractive quality, being ZDDP levels. One could choose an A3/B4, but that brings out the synthetic price tiers here. One also could get Delvac Elite 222 0w30 here, but that would generally require one to buy some rather large quantities of oil. It works for me, but may not work for everyone.
Hmm, I haven't looked for it at WM-I'm going to have to do that.
I have a half case sitting in the garage waiting for my next oil change in the MG...which is going to be in a few weeks when I pull the engine to change the transmission.
That particular half case came from Rural King, which generally has pretty good oil prices. As an example, the consistently have Pennzoil Conventional 20w50 for $2.75 a quart. The half case of VR-1 was $30, which isn't that much better than Walmart full synthetic prices. I think the last 5qt jugs of Mobil 1(5W-20) I've bought at Wal-Mart have been $26 and some change.
