Wife’s 2.4L Lat+ stalled while she was making a sharp turn. We took it to the dealer and the Rep informed us she was due for a oil change and it’s low a quart or 2 and claimed thats the reason it stalled. I call bull crap. So now, only 400 miles pass that oil change, it’s down about 2-3 quarts of oil. Will be taking it in Monday, but what should I expect? She has about 20,000 miles.

Anyone else having issues with the 2.4L burning oil?

Its common with a lot of 4 cylinders these days especially non turbo as they go with ever thinner oils and try to cut more and more friction to increase the MPG they can get out of them.

I can see if it was so low that when she went around the sharp curve, the system sensed it was out-of-oil, so it killed the engine...it's just a fail-safe. What I don't like is the fact that after 400 miles, it's already down 2-3 quarts. If that much were getting burned, I think you would be seeing a lot of smoke coming from the exhaust.

At that low of a mileage on the vehicle, it should be covered under the powertrain warranty. Don't take any $hit from the dealer as they may say it's "normal"' Keep up posted as to what they discover and good luck...

Run to another dealer! I have a 2.4L and I was using 1 quart per 1000 miles and it was confirmed by my dealer after a couple of oil consumption tests. After that confirmation and an OK from FCA, they replaced my entire motor under warranty. My dealer also kept my KL topped off with oil as necessary (no appointment needed) until the motor was swapped out. I got to use a new Charger for 3 days while they did that, hehe.

Also, the reason your engine died is due to VERY low oil...maybe a quart remaining. I was down 4 quarts when it happened to me in a turn as well. From the side of the road, I called my service rep and she said to put in a quart of oil and come into the dealer ASAP. I happened to always carry a quart of oil with me (part of my overlanding/recovery gear) and put in the quart and drove it there.

So I'd get to a dealer and INSIST on an oil consumption test asap.

Here's the info on the Service Bulletin (09-007-15) I was pointed to back in 2017...I'm not sure if it's changed though https://chrysler.oemdtc.com/682/engine-oil-consumption-guideline-2012-2016-fca-us

Oil Consumption
**The accepted rate of oil consumption for engines used in the vehicles listed above is 1
quart (0.946 liter) in 2,000 miles (3,200 km) for the 1st 50,000 miles (80,467 km). For
vehicles with more then 50,000 miles (80,467 km) the acceptable oil consumption for
engines is 1 quart (0.946 liter) in 750 miles (1,207 km).**

I had this issue and my dealer found scored cylinders. There were none of your typical oil loss symptoms, such as oil around the dip stick, or around the filter, or around the drain plug, or even around the motor. There was no smoke either...just disappearing oil.

I think it has more to do with trying to reduce internal engine friction with low tension rings than the actual thinner oil..


some 5w20 oils are only about 15-20% thinner than 5w30.

CR surveyed almost 500,000 vehicles built from 2010 to 2014, and found that the highest oil consumption was with Audi, BMW and Subaru vehicles. Jeep didn’t even make the top 30 list.

Honda extended the warranty on Accords and CR-Vs due to sticking piston rings. They stated that revving the engine when cold and the use of lower quality fuel contributed to the excessive consumption. Toyota lost a lawsuit and extended the warranty on thousands of vehicles due to excessive oil use. Not all new vehicles have oil consumption issues. It isn’t an industry-wide trend but rather a brand- and model-specific issue.

Update:



Took the Jeep to the dealer and as mentioned above, they started the consumption test. It was 2 quarts low, which he said was alarming. Well no duh, they should have actually started the test when I got the oil changed a month ago because it was practically empty.

I’ll keep you guys posted. Not really wanting a new motor, so I’ll probably just trade it in. I work for Chrylser...build Jeeps for a living and this makes me really upset that this issue exists.

Thanks. I took it today, they are doing the test. I’ll message you if I need help on the return visit.

how is synthetic 5w30 thinner than regular 5w30?
When it hits running temp, it get thinner than conventional oil.
Wow, I thought I had heard all of the myths about oil, but that is a new one!

Your statement is incorrect, as the viscosity of synthetic oil does not get any thinner at running temp than conventional oil. What makes synthetic oils superior to conventional oil is the fact that they maintain their viscosity better. In other words, a 5w-20 conventional oil as it ages will begin breaking down to it's base stock of 5w. Meanwhile, a synthetic 5w-20 oil after the same amount of miles will remain roughly the same 5w-20 viscosity rating.

With some reported exceptions, the 4 cylinder version of the Cherokee is known as an oil burner. If I owned one I would only use full synthetic oil, as conventional 5w-20 as it breaks down to 5W is more likely to burn away and lead to increased oil consumption. For that matter, I would run synthetic 5w-30 in it to further help the oil from breaking down. The only reason 5w-20 oil became a thing in the first place was to squeeze a tiny bit more mileage out of the engine. But in reality, any car that uses 5w-20 would run perfectly fine with 5w-30 and it would help reduce oil consumption in cars that experience it with 5w-20.

What I said is accurate. And the Cherokee does us full synthetic so that debunks your claim just on that basis alone.

I physically saw the viscosity test being done in person. And you can watch videos everywhere showing the difference, it will be proved that full synthetic is thinner when hotter.

#1 - only a relatively few 2.4 engines have experienced excessive oil consumption, so the problem is not oil viscosity. It’s those particular engines. Honda, Toyota and others have similar QC issues with some of their engines.

#2 - obviously if you can see it “everywhere” on YouTube then it must be true. No matter if the videos weren’t run by lubrication engineers to API specs, if you can see it it must be accurate. Heck, I hear that some brain surgeons learn their trade on YouTube....

#3 - Just to be clear, I don’t care what oil anybody uses. I don’t care if they use olive oil. I don’t care if their don’t check their oil level and end up with a seized engine. It’s your engine, do what you want with it.


:rolleyes:
