To the OP, have you asked if Chrysler has an oil monitoring program? A few years ago my wife's 2 month old new VW started eating oil too ...out of the blue. Dealer wouldn't do nothing so I kept adding oil for a month or two until I got fed up with it and found via the Internet they wouldn't do anything unless I specifically requested the car be put on their oil monitoring program. You'd think the dealer would have suggested this up front but no, i had to request it. Then for about a month I took the car in to get topped off with fluid every time the dip stick got to the 'Add' mark. The dealer would record the amount of oil added, mileage, etc. and it wasn't long until they called me and said VW wanted me to bring the car in. About 2 weeks later it had a new engine.
What caused the problem? About a week before it started eating oil the dealer replaced 2 glow plugs (the car is diesel - TDI). Well they over torqued the glow plugs and they broke and the engine ate them ...
07 two door rubi with 40k and change...no oil burnage here. And in my opinion burning any more than a quart per 3000 miles is terrible. For those folks burning a quart every 1000....I would expect you are having fouled plug and gas mileage issues too. I'm curious what your plugs and valves look like.
Chrysler states the 1 quart/1000 miles is not overly excessive! And no fouled plugs here, the PVC valve is fine, & no excessive fuel mileage problems! It's not a problem for me anymore now that i've switched to 5w-30. I haven't added a quart since making the switch!
I have the same problem as many others in this thread.
So it looks like those that have taken their Jeep to the dealer for service just get the run around
Hard to believe as burning a quart of oil per 1K miles is NOT Normal.
This is my 4th Jeep and have never had a problem burning oil with previous vehicles.
My mechanic (not a jeep dealer) told me he has seen 6 2008 Wranglers with this problem over the past year. He said I should purse it with Jeep Headquarters and maybe I'll get a favorable response.
I'm beyond my 3 yr warranty, but the power train warranty should still be available to work a claim.
Has anyone tried to file a claim with Jeep in headquarters in Detroit?
You receive a claim # and get in contact with the regional service rep.
I bought my '07 used with 18K at the end of 2010. It needs a qt every 1000 miles and has since I got it. Even my '85 GW doesn't eat that much oil. I feel like the 3.8L in my wife's 2001 Chrysler T&C must be the same engine as my 2007 JK, and it is spec'ed for 5w30. Can anybody comment whether they know those two engines to be the same design?
Royal Purple is good but there are better oils out there, Lucas Syn for one. My son besides three Jeeps has a MR-2. Their engines are a Yamaha 4-banger turbo. He found a 1.5 oil psi. pressure gain when he switched to Lucas from Royal Purple. He had gained 2 psi when he had switched to Royal Purple from Mobil One. At idle. Viscostity(sp) break down.
When we were looking for 2013, another family were looking for one as well, he complained about oil consumption on his 3.8. I think the 3.8 in a Un were being flogged pretty hard. They didn't have that rep in minivans. Sorta reminds me of driving behind a kid in a Civic.
