2.4L oil consumption

[PLP]

I also suffer from high oil consumption.
Between changes I drift from full (max line) to about minimum in the mid run (say about 3000 miles). Refill - that is 2 quarts, and same for the remaining 3000-4000 miles until the OIL CHANGE indicator comes on.
None of my cars that I have ever owned would use this much oil, except those that had over 100k miles, but still not so bad.

I use 0W-20 (as specs) Pennzoil Platinum from the very first change. Only once for the whole period "only" 3 quarts were consumed.

I do not agree that this level of consumption is justified.
I would agree that owner should check oil from time to time (each fill up is a bit too often for a relatively new car without any LEAKS or other problems) and refill as needed, but with other cars that do not require oil tops off - 2.4 tigershark is a something like going back in time.

Even mine 1.6T GDI in KIA that I push quite hard so many times does not need this much oil (running 5W-30 same brand).

Any of us that are concerned about the oil consumption of our FIATs should google "consumer reports oil consumption article". The article won't change the behavior of your FIAT, but when you get to the list of the top 30 oil guzzlers you will have a big smile on your face.

Hmm. That is weird.
2.0T is very common in VW/Audi family. Even Porsche uses it.
Yet, Audi was there, but not VW...

Yes, the article shows problems, but it does not really treat all participants equally.

You cannot compare NA-1.6 I4 to TT-4.8 V8. Not only turbo charged engines eat more oil by their nature, but 4.8 is 3 times bigger than 1.6. Hence, it has much more oil. Hence, 1 quart for it is nothing comparing to 1.6.


Going back to the topic.
It is weird - now the oil consumption stopped again. I am not sure. Is it weather related? Petrol? Style? I use same oil... that is same brand, grade. Different batch, though.

Im sure it will start back up. Checked roomie's Cherokee again and she was a quart low. Not sure how many miles but it was basically after a round trip from Florida to Virginia so I'm guessing about 2-3k. Seems these engines should have a low oil level warning light for those that don't think to check it regularly.

There's a theory on the Dart boards that its the PCV valve stuck open. Once the PCV valve becomes unstuck and working again the oil consumption goes back to normal. Might be worth it to just replace it for $16.

I have a 2018 500x Urbana 2.4L and had to add oil 3 times before I even hit 4,000 miles. Turns out there was a manufacturing defect in my engine where the cylinder heads were scored and now my car is in the shop waiting for it's new engine. I should have it back by the end of the week. I had a 2016 500x Easy that never burned a drop of oil, but from day 1 I used the 0-20w blend, not straight synthetic.

Latest Power train software update supposedly fixes the oil consumption issue with the 2.4L. The Jeep boys some claim it completely solved it and some claim it is cut in half. The software change allows the valves to stay open during deceleration thus curing the high vacuum condition (no more oil getting sucked past the rings).

As I understand it, that change mostly illuminates the oil change interval sooner. Keeping the valves open simply covers up a design flaw.

"But a defect in the Tigershark engine means the piston rings don't work correctly with the cylinders. This allows oil to seep past and burn off in the compression cycle. As the engine loses oil, excess heat and friction will prematurely wear down internal components. At first the engine might stall out. But eventually it'll seize up and fail."

Official Mopar said:

Hello, the oil consumption concerns are caused from vacuum being created in the cylinders during deceleration. Software changes the events, internal to engine, that lead to creation of vacuum.
If you need any help setting up an appointment, feel free to let us know.

I’ll share that with my daughter, on her Renegrade. 6 years late, never can hurt.
