I've been running Mobil1 10w-30 synthetic in my car because previously it was running 5w-30 and noticed that warm idle pressure after about 2500 miles would drop to about 30-35 psi whereas when fresh it'd hit about 40 psi. I recommend either the Wix, K&N filter with the wrench off nut at the bottom or the recommended Mobil1 filter.
Sorry Demon, but I got to side with John there, Fram is about the worst filter imo that you can ever use on a car. Can't remember where it was that I seen it, but on a comparison chart, fram was actually the worst filter tested.
