oil vanishing
 

i have this common problem that my jk is eating oil at a rapid rate, no leaks and no obvious signs of burning oil. any one else here have this issue and how are they dealing with chrysler about it. iv just started to address this with the dealership and so far their back stepping big time. my oil pressure light came on and this is how i found out about it i wonder if my engine has already sustained damage from running so low. any thoughts?

Re: oil vanishing
 

I have an 09 2 door JK and so far I haven't had any issues. I've got 48,000 on er too.

Re: oil vanishing
 

i had a o7 4dr with 52000k when they change the motor. it was taking between 3 and 4 liters of oil every 5000k

Re: oil vanishing
 

My 07 Sahara Wrangler is taking one quart every 1500 miles, the dealer d'ont know what to do I am trading it in as soon as the 2012 model come out (with the Penstastar and 5 speed auto)

Re: oil vanishing
 

u should keep changing oils on a regular basis like , like after every 10000 miles or something.

Re: oil vanishing
 

YEIKS!!! This is the first motor swap I've heard of.

I've been following this topic very closely on other forums, and it sounds as many (many) early JKs have this issue 07/08...not sure on 09's. Finger is pointing to pistons rings not installed correctly, no news on a batch or lot of motors to narrow it down yet.

Ahhh. Upsetting to say the least.

I've said it before, but I'll say it again....lift the hood check your oil on a regular basis (every fuel fill up) don't get complacent and just wait for the oil change time to come around. It takes just a few minutes out of your day.

I have not noticed any oil consumption yet...08 JKU with 41K on the clock.

boardman<<>>im haveing the same problem as you,,my 2008 jeep wrangler is eating oil,,2 quarts for every 1200 kms,,,this is INSANE,,if you view some other forms,,WERE NOT ALONE,,,there is 100s of us and ppl have started to join together to challange chryslers,,1 quart every 1000k laws,,,,BOARDMAN my dealership is working with me,,we have started the ball rolling with monituring the oil,,,YOUR not alone and as jeep owners we were the UNLUCKY ones ..

Re: oil vanishing
 

I gave up the fight, 3 dealerships and Chrysler engineering dept and I'm eating more oil and their response too bad buy a new one and your issue is resolved. Wtf... I sold the jeep and my caliber too I'm done with the big piece of **** three. Good luck with your fight

Re: oil vanishing
 

boardman??? why did you give up???was your jeep still under factory warrenty?? if it was under warrenty and eating more than the amount of oil than chrysler says is normal,,you should have got a new engine,,,i have seen some horror stories,,but i have seen some stories about chrysler actually giving ppl new engines and fixing there problems,,,

Re: oil vanishing
 

yup still under warrany, but chrysler states its acceptable to consume 1 - 1.5ltr per 1000km. their sticking by this clause and clearly told me they wont replace the motor as im not consuming over this amount. my wife is was so fed up and disgusted with them after what we spent she pulled the plug. she bought a kia and couldn't be happier. it kills me to write this as im a jeep fan for life. i think ill buy a jk still but it will be used and my buddy said he can swap the motor with something better. good luck with your fight i honestly cant say you will win with them but i hope the best for you

Re: oil vanishing
 

I bought a 2008 JK 6 weeks ago, and the change oil light came on after 1500 kms. The oil is low and looks like crud - I'd assumed the dealer changed the oil before the sale, but now I don't know. The engine runs like a charm - it sounds like an electric - so I'm not worried yet. I'll just add oil and change every 5,000 kms as per my normal routine. Thanks for the head's up! I have no complaints with my Beast, but I will keep an eye on it.

Re: oil vanishing
 

it seems to be a random issue involving internal parts. it didnts start till my jeep past the break in period. then it only got worse. most jeeps seem to be ok its the ones made on friday i guess.lol

Re: oil vanishing
 

I heard there was a batch of 3.8's assembled in Mexico with the slots in the piston rings lined up. I have also heard of many people having their engines replaced under warranty. Dealer must do a leakdown test on each cylinder to find an affected pistons.. If the dealer won't do the leakdown have a different shop do it and have the results documented and signed by said shop...
Some say switching to 5W30 oil will also ease the usage, but if under warranty I would want it fixed.. If not under warranty there are a few places where you can get a slightly used 3.8 for less then $1000.
Unfortunately switching to a different manufacturers engine will cost you a lot more then a new 3.8. Not an easy swap with all the computer control..

Re: oil vanishing
 

see this is WHATS MAKING MY BLOOD BOIL...how can they say this is a NORMAL amount,,,thats 5 quarts of oil per 5000 km,,THEN add on another 5 due at the change,,,thats 200 quarts of oil per 100 000 KMS,,,a ARMY TANK dosent use this much oil,,,PLUS I KNOW when you get up to 130/140000 kms your engines gonna CRAP OUT,,it seems like to me chrysler is doing everything in there power NOT TO HONOR there 100000 power train warrenty...i CANNOT SEE boardman why your dealer wouldnt help you,,,its NO SKIN OFF THERE ASS if you get a new engine,,,,your happy you get a new engine,,and there happy becasue they install it on chryslers dime..i think i have it figured out,,,JEEP put out a bunch of jeeps with crappy parts and crappy labour,,and knew if they recalled the jeeps it would cost the company millions,,so they just changed the paper work on the power train warrenty to cover themselves,,,leaving there jeep custumers to foot the bill on 20/30 oil eating jeeps,,,,I THINK IM RIGHT,,maybe i aint,,,but im SMART,,,just not smart enuff to pick the red jeep on the lot,,i picked the yellow 1,,and the red 1 aint got no oil consumption,,,SHOULD HAVE went with red i guess,,,seeing its MY FAULT i picked yellow,,,wish i could have read minds and had xray vision so i could have seen inside the engine,,,i havent measured what mine is burning,,so i cant say for sure,,,but its CLOSE to 1 quart every 1000 kms,,,why dont they just put it up to 3 quarts for every 1000 kms cuz this is NORMAL,,5 quarts per 1000 kms is NOT NORMAL,,even the guys at my dealership said this amount was INSANE

Re: oil vanishing
 

See that's the problem. your dealer is saying it's not right but they blame Chrysler for not covering it instead of taking this to the next level and doing a leakdown test. Find a new dealer or deal with Chrysler directly. If the leakdown test proves (and it will) the faulty assembly Chrysler will replace the engine.

Lifetime Powertrain Warranty Scam? Your Warranty May Mean Nothing - Internal Chrysler Documents Revealed

In additional to blaming consumers whenever possible for engine failures covered under warranty, Chrysler also tells dealers in an internal memo that it is normal for their vehicles to consume up to 1 quart of oil every 1,000 and 1 quart every 750 miles for engines over 50,000 miles! Many engines only hold 4-5 quarts on average where you may be dangerously low on motor oil sooner than you would expect. Chrysler is avoiding honoring warranties for problems such as excessive Oil consumption, which is often an indication of future engine failure. To avoid defective Engine warranty claims, Chrysler sends internal memo to dealers stating that acceptable Oil consumption for Engines below 50,000 miles is one quart per 1,000 miles driven! Acceptable Oil consumption for Chrysler Engines with over 50,000 miles is one quart per 750 miles! For more proof, ask to see the memo at your local dealer

Re: oil vanishing
 

my dealership is monituring my oil consumption as of yesterday,,i have to check my oil and return to the shop when i add on another 1000 kms,,they need documentation to give to chrysler to get the ball rolling according to them,,my worie is that its gonna show im burning 999999.9999% of a quart and i wont fall under warrenty,,IM SO STUPID,,,if i would have REMOTLY knew the word OIL CONSUMPTION even existed i would have NEVER NEVER bought a chrysler...here is WHATS gonna happen<<>>im gonna be burning 1 quart per 1000 kms,,,chrysler isnt going to fix it,,,im gonna dump oil into it until it gets off factory power train warrent,,then its gonna explode,,and im gonna have a jeep i gotta make monthly payments on for 4 more years with NO ENGINE,,,thats whats gonna happen to me....

Re: oil vanishing
 

Chrysler is certainly not the only manufacturer with oil consumption issues. You could have bought a GM and have sloppy pistons or a Ford with rattle valve train.. All manufacturers have their lemons..
None the Less I would be upset too if I were you. Speed this along get a drill powered pump from CTC with a long slim hose and suck an extra 1/2 quart out of the dipstick tube if you have to before you take it in for the check.. I really don't see how monitoring and documenting your oil usage as you outlined is going to prove anything. There is no way it should be using 1qrt in 1000klms In the states they state 1000 mi (1600klm).
Can you not get them to do a leakdown test...? In the end this would be faster for both of you.. Is there not another dealer you can talk to.

Re: oil vanishing
 

I remember a few years back my old boss had an oil eating Chevy....they wouldn't do anything so he drained the oil, floorboarded the gas pedal. Amazing how long it run. Anyhow, filled back the oil and flatbedded back to the dealer for a new engine...remember kids...don't do this at home.

Re: oil vanishing
 

Hi again,
There's a technical service bulletin (TSB) from November 7, 2007 about
" 3.8L Engine Oil Seepage Due To Front Timing Cover Surface Porosity" . It's TSB NUMBER: 09-008-07. If you google TSB for your year and model, you can find various sites with the TSBs on such things as paint etching, leaky freedom tops, and others. There might be quite a few things to take to your dealer. It's recommended that you print relevant TSB/recalls and bring them in when you go.

Re: oil vanishing
 

I'm amazed when I hear these stories....Yes I work in the auto service industry.

I don't understand when dealers don't tackle these problems. They are paid by the manufacturer to perform the repairs. Warranty labour times do not pay as well customer pay times, but none the less it is work that pays!

1L of oil every 1000kms.....Maybe if you drive the living hell out of the vehicle!

Normal accepted level is about 1L every 3200kms (2000 miles). I can understand any dealer wanting to verify the oil consumption (Warranty loves documentation).

Do an oil change (At the dealer) and drive in there every 1000kms and have them check it (Make sure it is documented on a work order). After 2 visits where they've added a litre each time, on the third visit repairs/replacement should be done.

Yes, it may seem like a lengthy process. On my end this has also proven to customers that their vehicle is not consuming oil and has saved in my case GM big $$$. It has also proven to GM when a repair/replacement is required.

Re: oil vanishing
 

Try switching to 5W30 on your next oil change. This worked for my 08 JKU when I started to consume about 1.5L every 5k km's when I hit 60k km on the odometer. Since the switch I have next to nothing for consumption. If that does not work then try replacing your PCV valve.
