Diesel guys...
Been unavailable for about a month or so...
I like me some T4 10W-30 for my old pickup.
I was in Wallymart last week and the oil selection was low. I was looking for Penzoil Platinum for the first oil change in my new truck and the selction was pretty thin but for their house brand of oil. I wanted to try the Rotella for gas engines but OOS. I think it was mostly all out of stock for Rotella. I ended up getting the Motorcraft 5w-30 semi-synthetic which is the spec oil. I also wanted a Motorcraft filter too but they were out of stock. If I can't get a Motorcraft I'll check into a Wix but I like to get it all in one place.
WixXP is a fine substitute for Motorcraft. The straight up Wix is their filter for the lube shops and OK, but not as good. WixXP is also the oil filter that NAPA sells as NAPA Gold line.
