Just to pile on to the Mobil one filter bashing....I put one on my old YJ and it increased my oil pressure by 15psi (hot & cold). No other changes, same brand/weight of oil. I already had good oil pressure so I took it off and my pressure went back to "normal". I use Puralator PureOne filters now with Mobil One oil & have no complaints.

Same here guys. Mobile 1 oil filter and Mobile 1 0W-20 is what I was running. Engine made a knocking sound on startup kinda like when you crank the motor right after an oil change. I changed to fram extended guard and added a little more 0w-20 for what I lost and the noise went away. I wouldn't run a mobile 1 oil filter ever again. I'll probably go back to 5w-20 after 3,000 miles. I had that garbage on my truck for about half a day.

Well I changed my oil this weekend and went with a AC Delco PF53 filter and it was cold this morning when I left work and low and behold I still had the knock.... Time to swap it out for one that others have had success with.

I switched out the mobile1 filter for the motorcraft FL-400S and the knock is gone. My knock wasn't too bad, but I was worried about it anyway. Now, no more knock.

Great topic guys. I switched over to Mobile 1 5w30 and a Mobile 1 filter and have had the same clater on startup. I thought it was the 5w30 vs 5w20. I will pick up a Motorcraft FL-400s on the way home tonight.

OK picked up the Motorcraft FL-400s filter and clater is gone! great advice. I also talked to the Autozone guy and he confirmed the same thing Modile 1 filters do not have the valve that retains the oil pressure for start up.
So the 3.99 filter is better than the 10.99 Modile 1

I switched to Mobile 1 and their filter a couple weeks ago and immediately noticed the clatter after the Jeep sits. This weekend I am going to buy a Mopar filter and replace the Mobile 1 filter and see what happens.
