oil filter /w anti-drainback valve
Hey, quick question. What brand of oil filter comes with an anti-drainback valve? I’ve been using Mobil 1 oil filters but I heard (can’t remember where) that they lack an anti-drainback valve.
Is AC Delco the only one with an anti-drainback valve? (or do they even have one?)

Hmm I suppose I have'nt, this last oil change I just looked in the Autozone filter books for the equivalent Mobil 1 filter to the pf-44. (a smaller one evidently)

The 03's use a different filter than the 02's. I think the 02's use the same filter as the previous models though.
The part that screws into the filter is smaller diamiter, so it isn't something that is longer or shorter.

the filter for the 02s are longer than the 03s, they both will fit on either trucks.
the K&N oil filters have the anti drainback valve as well

Re: oil filter /w anti-drainback valve
PF44 is no longer available. PF46 i belive is the new filter number. Delco filters have an anti drainback valve, the only filters i've seen without are ones jiffy lube or quick lube places use. Wix filters or Napa Gold (both are the same) Patman has said to show good flow numbers, K&N obviously the best. So what is the difference between the 02 and 03 oil filters are both compatible with each other?

Just to confirm what fullfloatingHD said, PF44 is discontinued, PF46 is the new number, this according to my dealer who I saw today.
No, I did not let him change my oil for me.
