Full Size Spare tire

Uh oh I sense an oil discussion brewing! Lol.

FWIW, I use a group 3 or group 4 synthetic (Amsoil) and change my oil & rotate tires every 5k. Its easy to keep track of (anyone can divide by 5) and I know its safe.

Pretty much my situation (Mobil1) I just choose 6k since the suggestions ranged all the way to 8k which I felt was to long.

You can get oil analysis done to prove the oil is good. I have never heard of an engine failure where the owner was on a legitimate oil change cycle... whether it be 3k, 5k or even 7.5k. Use a quality synthetic oil, stick to a good schedule and don't stress about it IMO. If you do happen to have a major failure (unlikely) then grab a sample and have the oil tested. That will either prove to your warranty company that the oil wasn't at fault OR if it was, most oil companies have their own warranty and should cover you there.

Thanks guys, being a punk 23 year old and every other 4x4 I have owned I have bought cash then trashed the sh*t out of it and sold it for nothing. Since I owe on this one still I am trying to be a responsible owner and keep this one around. Ill switch to synthetic next time, and see how it goes.

Just treat the jeep right and it will treat you right. Upgrade to synthetic fluids in your diffs as well when you do the service. Put quality parts and fluids in your jeep and you and your jeep will be happy. All my vehicles have had ridiculous miles on them and they were running great when I sold them.
