Which Oil filter do you use.

[OR VietVet]

They have a case of 6 of the 51042XP for $72 at Amazon. None of either of my numbers at RA.

I think you meant 51042xp, correct? No such number as 52042xp at the Wix site.

That’s correct. I got to typing too quickly

51042xp I found one on ebay for 16 bucks free shipping ordered.I have been doing a quiet test on oil pressure with different filters.Wix will be my last test-i have only tested 2 so far.Mobil 1 and royal purple.Mobil one gave a higher pressure reading and i thought that was interesting.This is 3-5k miles in between oil changes.

If all else fails, you can use the NAPA Gold oil filter for a good quality WIX made filter.

Used NAPA Gold on my 4.0L Jeep for several years. Seemed to do pretty well. I was satisfied. Some other brands of filters had flimsy back-flow valve "flappers", which can make a ticky sound almost like valve lifter tick. NAPA Golds filtered good and did not have any noise from the back-flow valves.

Quality WIX filter made for NAPA.

I'm surprised @swathdiver hasn't chimed in here yet. I believe he's done some "oil filter effects on oil pressure" tests a couple years back.

Well, the fellas here like Wix, a fine filter, but it is not the top dog.

Alright, this was done about 2018 or 2019:



I have personally used the PF63E, the M1-212A and the HP2011 on my truck. The Mobil One filter dropped my oil pressure about 2-3 psi compared with the other two. From the 1980s through the 2000s our family used FRAM filters without issue, even when we were broke and had to reset the OLM a few times. I used ACDelco filters in my muscle cars back in the day. Probably going to buy a case of PF63s for the Sierra since it goes through oil changes every two months. The K&Ns are probably the most expensive, they are about $15 each right now. The PF63s are $8-9 each.

Did the oil filter threads change with the GMT-900 models? My '04 filter has SAE threads.
