Just completed my first oil change (both ever and on the 1999 since I bought it). You may have already started but don't forget to check for the old O-ring! I yanked off the old ACDelco (gag) filter and didn't even realize that the O-ring didn't come with it until I fired up the Jeep, built and lost oil pressure, and my wife informed me of the sudden leak
Newbie mistake for sure. I used a lot of paper towel today lol

K&N filter is the same as a Mobil 1 but with a wrench head welded on. Both are great filters. I just save the 3$ difference. Also I run Champion Copper tops on all my Jeep motors.

Definitely agree with the filters and the wix/napa gold are cheaper than most filters, Purolator gold is another decent one. Synthetic will cause more leaks. I use rotella 10w-30 and I LOVE it. I do however disagree with the NGKs all my jeeps love Champion. As a general rule of thumb I try to keep domestic plugs in domestic cars and import plugs in import cars, things just seem to run better this way. There have been exceptions but thats what works for me.
I have had 3-4 Champion plugs go bad when they were very "young" in more than one vehicle. They were adjusted under a defect warranty. Switched to NGK because I was getting tired of changing bad Champions. Have never regretted it.

I switched from dino oil to Mobil 1 in my '87 Cherokee many miles ago with no ill effects. No leaks. Jeep has 210K miles on the original engine. Might use 3/4 quart in 8,000 miles.
