I have 09 unlimited and 2 weeks ago smelt it burning oil while driving it went to gas station and it was just about empty put 4.5 quarts in it i been checking it everyday and it is not leaking from anywhere and everytime i drive it once the engine warms up i smell it burning it only last a few minutes. it hasnt gone down a qrt yet but i check it everyday after work and can see the difference on the dipstick. i was reading on another forum that some burn a qt every 1000 miles something chrysler says is "normal" but the smell is not so pleasing if i have passengers. any ideas what to do? my boyfriend hopes the engine doesnt blow up from there being no oil in it 2 weeks ago and says im going to waste my money to get it looked at bc they will tell me what i already know. he says to just trade it in.

It is a known issue that some 3.8L engines use oil. Yours is the first I have heard of smelling the burning oil. Do you see blue smoke coming out the tailpipe? You could be leaking oil. It would then drip down onto the exhaust and cause the smell. Not much can be done like this. You will either need to check it out, have your boy friend, or a good mechanic do it.

If it isn't leaking.....TRADE IT !! Running it that low may cause damage to the rod bearings. This damage will surface at a later date...(Engine knocking,Spun Bearings)...
Look under the Jeep at the exhaust pipe, look for a BLACK spot where the oil may be dripping onto the pipe and burning, causing the smell...Maybe a valve cover gasket.
Your not alone ! I own one too.... I changed to a 10W-30 motor oil and this reduced the oil consumption where I can drive it with out too much worry about running out, and I carry a couple quarts with me at all times....JEEPS take 6 quarts to fill...
Good luck with it...."BH"

my 2011 3.8 started out slow then soon started using 6 quarts in about 1500 miles no leaks and under 36000 miles I would think about trading it in

Before you decide to trade it, etc., there are a couple of things you can do. If I owned it I would switch to 5W30 and also replace the PCV. That could possibly solve the problem regarding consumption. The oil odor would not be coming from the tail pipe. You most likely have a small leak that is dripping on the exhaust, parts of the engine or trans., and then it burns off. You definately have to check the oil level often. Unfortunately, Chrysler indicates that burning 1 qt. per 1,000 miles is "normal" for a 3.8. Many of us definately don't agree with that but they make the rules. You're not going to see blue smoke coming out of the tailpipe anymore like the pre-cat vehicles because the newer cats burn it off. You'll still burn oil, you just won't see it. If the heavier weight oil and PCV swap doesn't solve the problem then selling it might be an option.

Yeah I joined the oil consumption party as well 2010 jk and it uses up oil bigtime.I switched to 5w20 synthetic hoping it reduces this problem.Since I've owned this jeep all my fears of only a Chrysler product have come true.I can't say I didn't know Chrysler was sub par in quality compared to almost all other brands but I really wanted a jeep.Ill most likely start researching about swapping in a crate engine 350 see if that's doable.It would take less gas,have more power and not burn oil!!!

Burning some oil, as long as it doesn't foul out your spar plugs, really isn't that big of a deal!
Just add some oil when needed, and extend out your oil change interval, because of the replenishment.

The real issue is, that some don't check their engine oil level, or know how too, but what's even worse is, they don't understand that it should be checked...........:crazy::crazy::crazy:

Hah I've met my fair share of those....they always seem to be the people who pay too much to buy their cars and who seem to repair them more often than others

Yes, it's sad that somebody has never educated them regarding maintenance procedures!
I guess that they just turn on the key and go, until it won't go anymore.

I just helped my 15 year old Grand-son find a nice clean 2004 Tj with low mileage on it.
The first thing that we did when he got it home was, I handed him my grease gun, and yes made sure that he hit every zerk. Next he checked all of the fluid levels.
This weekend I am going to help him change his engine oil. He now has a chart made up as to when to check his engine oil, and coolant, plus tire pressure in the am when cold.
I will make sure that he is educated on both maintenance and safety..........:thumb:

I also introduced him to our Forum, so he can start to learn about his first Vehicle/Wrangler!
He is all smiles from ear to ear!:D

Maintenance is always important and a must do at all times.However it doesn't justify a poor quality engine burning through 1 liter if oil every 1000 miles either.

This one might be something different. No one else with the consumption issue has mentioned smelling anything. The OP may in fact have an oil leak. My guess is a leak at the rear of the engine that is hitting the exhaust and burning off which is causing the smell. I would advise to have this checked. The normal oil consumption issue usually occurs with 08's and some 07's. He has a 09. Usually when an engine burns oil, you don't smell it in the cabin.

Rear main seal leak usually comes out by the transmission but it could be something similar or if it can somehow get to the exhaust that could be what's wrong

What is the recommended oil? I just picked up an 09 and didn't know this problem. Here in Utah it does get cold. Would 10W 30 be the best approach against burning oil? Sorry to jump in.

Mobile V-Twin synthetic 20-50 w motor oil

Hi, Maybe this will help keep the oil in the crank case ?
I've been riding big Harley's most my 65 years an by 2,000 miles you need a qt. of oil .
I've been running synthetic oil since I found out that syn don't boil till +400d.
I saw the advertisement about the V-twin oil years ago an now I change my oil 4-5,000 miles my oil level is about full .
The V-Twin syn oil has an additive ?? or something that is benifical to oil retension .
Maybe you should try this oil ?? Good luck . Biff

Recommended oil is always printed right on the fill cap. In your case it will say 5W 20. Unless you are having issues, that's what you should be using.

Sorry I might worded that wrong I was referring to what oil would be best to use if this prime was happening.

Well, I went from that awful 5W-20 to a 10W-30, It works fine, the engine hasn't exploded yet....US cars and trucks have used 10W-30 for many years.
The same people who tell you to use 5W-20 oil are the same ones telling you that 1 quart of oil consumption in 1000 miles is "NORMAL"....( they get out of buying NEW engines that way !!)

You might try as I did, try different brands of oil and see which brand your engine likes...
I settled on "Castrol 10W-30 Extended Milage Vehicle Oil" this is a Synthetic Blend....Comes in the Green Jug.
Other Forums ( the Mini Van Forum ) have swapped PCV valves and have not had any luck as far as Slowing the Oil Consumption. Your welcome to try, anything is worth a try.
There are lots of posts here as well as on other Forums about this issue.
Causes thought to be Incorrectly installed piston rings at the Mexican Engine plant. ( Replace the piston rings )
Spinning rod bearings causing the Oil Shear to go away and the oil to be consumed inside the engine due to heat generated .( replace the Rods with MOPAR replacements )
Lots of Thoughts....
If your bucks up, have a new set of piston rings installed . Rings are pretty reasonable, around $75.00/set last I checked....Labor is going to be around $75.00 or more per hour $$$$$$$$$$.

To the OP: Sorry to get side tracked here.... You may not have an oil Consumption problem. If you can SMELL the oil, you may have a leak, so look for that leak and get it fixed and then keep your eyes on that dip stick !!
Good luck..... "BH"
