I have always run the Mopar M0-090 and M1 10w-40 High Milage.
97 Wrangler 4.0 150k miles, burns zero oil, excellent oil pressure for a 4.0 of this vintage and milage (15psi idle, 40 at highway speed when hot and thin), but has some timing chain noise during warmup, which goes away at operating temp. I am ignoring this noise lol. I hope it is just timing chain noise.
Couldn’t find the Mopar filter yesterday, I have no idea who makes it now (Wix?).
All that was available was the Mobil M1-204A. So I (stupidly?) bought it.
I’ve seen a number of disturbing reports here in years past about incomplete filter media and shoddy construction in the Mobil filters. Is this still happening?
Should I take it back and wait until I can find a better filter?
I don’t care about the cost, I just want to change the oil today.
