JK oil use


Here is a good question. I have a 2009 JK with the standard v-6. I change my oil regularly every 3000 miles, (or whenever the Jeep tells me it wants changed). Between changes I regularly have to add up to two quarts to keep a safe level. Anyone else have this "anomoly"? Engine does not smoke so I can't believe that it is burning oil, but where is it going??? Hmmmmm

JK oil consumption specs are 1qt per 1000 miles - so if you don't ever check it and you get to the next oil change, it's perfectly "normal" to have no oil in there.

Welcome to the wonderful world of Jeep ownership.

Whenever I change my oil (no that often, I go 6K or more) the waste oil fits comfortable in the empty 5 qt container some of the new oil came in. Always has.

my 08' is at par with your motors consumption....been like this since day one, i change every 5000km ( 3000 miles ) and am lucky if i get 4 litres with filter in waste at change time. Motor runs mint though so i will just keep checking/adding. i have 67,000 km on it

Thanks for the repies. I have 67,000 on my Jeep and it runs like a top. I have just never owned a vehicle that "disposed" of oil without smoking. Bought this one with 1 mile on odometer. Didn't notice till about 30.000 or so. I am relieved.........

Never had any oil consumption on our 2009 with the standard 5w20.

My 2007 used to consume oil with 5w20 but I switched to 5w30 and it hasn't consumed any since...

the oil consumption "issue" is pretty well known. same engine in the earlier minivan and they had the same problem in there, too.
its completely random. some dont use any oil at all (mine for example). others do. some... alot.

What is odd about mine is I didn't notice in the first 35 to 40 thousand miles. Then one day I was changing the oil and only got about 3qts out of the pan. Been that way since..

Mine was using between 1 and 1.5 qts every 1,000 miles it was also rattling to beat all hell. With 2K on an oil change it was missing nearly 2 qts. I took it directly to the dealer and they started the oil consumption test. Five thousand miles later I got a short block replacement.

Hey Steel Blue, Welcome to JKO. I have been thinking about bumping up to 5w30 have heard positive results from that also.

I change my oil @ 5k intervals. I check it regularly & have never needed to add in between changes. I use the recommend 5w20 of my choice (Royal Purple) & Mopar oil filter.

I switched to 10w30 Mobil 1. All seems well but only about 500 miles since the switch. Always used Synthetic from the first change at approx 3k miles.

BUT....

part of the reason that I switched is that ever since a road trip that I made last year, she's been losing a little bit very slowly over time. In fact... after that 500+ mile trip she was down a good qt or so.

Prior to that my ('08) JK had never lost any oil. That long trip seemed to have played hell on some seals somewhere.

Your posts remind me of a mood-ring or something.

Hey Stub (and OP), have you checked the PCV tube and intake for excessive oil? Pretty sure that's where a lot of mine was going, started using some after about 60k mark.

Read a thread recently which suggested Chysler has acknoledged possible valve stem seal failure can be the cause of this issue. Pretty easy fix.

I can't recall which forum I read that on, but you can do a search and maybe find it. So far the issues identified have been bad bores in Mexican-built engines (2008), PCV valve failure and weak or incorrectly installed oil control rings. Oil burners usually will have excessive hydrocarbon emissions and should either trigger a MIL, or fail an emissions test. The catalysts will burn off most visible smoke until they start to fail. However, I have yet to read of a JK with bad cats, or failing emissions due to this issue. If it did Chrysler could be on the hook for a repair under the emissions performance warranty.

It's really important to check your oil frequently. I do it with every fill up religiously. If ou have an issue you'll discover it early on and avoid the "lack of lubrication" excuse the manufacturer can use on you.
