Im in the 1qt for every 1000 miles club. I have switched to 5W-30 and now burn a qt for every 1200 miles. Im planning on going 10-30 for this next change and seeing what happens. Im using Pennzoil Platinum Full synthetic. I may try dino after the next run.
I did find oil in my pcv valve hose. So I will be replacing that also.

I had the same problem with '07. Unfortunately I didn't find out until it was to late. Didn't have a hint if trouble, changed the oil religiously every 3,000 miles. The oil light flashed once or twice. Never heard a knock. When the light flashed checked the oil and there was only one qt left! Toon it right to the dealership (after putting oil in of course! LOL) and the first thing the service rep said after I told him what was wrong was "Call Chrysler and start a case". They check the engine that day and it was shot, metal shavings in the oil. The warranty was up, I didn't have an extended one. Chrysler was pretty good about and replaced the engine and split the cost 50/50. Needless to say I just traded in the '07 and got a new Sahara, with an extended warranty I might add!!

Play it safe and avoid the 2007's, 2008's, and early 2009's.

I hate to dodge an answer, but I would say it's a personal preference thing. It certainly won't hurt to change every 3K, that's obvious... but I'm not sure everyone has the conviction they could go 4K, 5K or longer.
I personally think 4K is pretty reasonable for conventional. 5K may be ok if you are in a warm climate or during the summer months. Winters are harsh on motor oils, so I change around the 4k mark.

Unfortunately for the used consumers, Jeep has been buying back the 2008's with the lifetime warranty, then sticking them back on the dealer lots and selling them As-Is. Several guys here reporting getting offers of trade value equal to their original buying price. Jeep knows the serial numbers of the vehicles that have the bad engines and wants to get out of the warranty obligations.
Play it safe and avoid the 2007's, 2008's, and early 2009's.

I am the original owner if an 07 rubi with 62k miles and a lifetime warranty. It has not had any oil problems and Chrysler has never offered to buy it back. The only problems so far were a rear seatbelt, gastank and steering stabilizer. Very happy with the jeep.
