walmart here actually sells the AC delco for my car and the Mopar filter for my Jeep so makes it easy and cheap to buy them. Bought a case of AC delco's for the truck when I bought it. Have enough filters to go to 100k miles.
Yeah, Walmart sells both the ACDelco filter I need and the Mobil-1 Synthetic I like to use. At about half of what the GM guys sell them for, so that isn't a hard choice to make.
I have found the STP filters from AUTOZONE to work best for me. They are made by DEUTCH, but AZ changed the name on them as everybody kept calling them dusche filters. I ran WIX a few times and got the infamous DMAX typewriter tick REALLY bad, but I don't have it with the STP's. Also I have found that they all seem to have a drainback valve in them as well whereas some others won't have it.
Used a NAPA oil filter on this truck the first couple times, but since all I have used have been Fleetguard filters including on the FASS fuel pump as well.
I'm don't have a preference for brand name. right now it's got a cheap store brand on there. the good ones go on when they're on sale. mind you the oil doesn't ge very dirty when you keep topping it up again.:rolleyes5:
