Problem seems to be fixed with using thicker grade oil such as 0W30.
Noooooooooooooo don't do that! You don't know what you are saying. That is still zero weight oil either way, 0w20 and 0w30 are the same viscosity other than at cold winter startup. You know where your engine really doesn't need any decreased lubrication and increased friction?? COLD WINTER STARTUP.0W-30 sounds like a good plan.
Changing oil viscosity is the most foolish thing you could do, bar none. Believe me, if Jeep engineers who have studied this issue carefully came to the conclusion that changing the recommended oil viscosity was the simple, easy solution, THEY WOULD HAVE DONE THAT FOREVER AGO (and it would have been probably a 5w20 oil, not another zero-weight) That would be worlds easier and cheaper for them than trying to reduce the issue with PCM reprogramming. Please use your heads and don't go putting the wrong oil into your motor because "you read it somewhere on the internet". Someday you'll probably sell that car and stick some other poor fool with a damaged or prematurely worn motor if you don't take care of it properly and follow the manufacturer recommendations.
I thought the same, and I do believe ultimately it IS still burning it, but my new theory based on new evidence is that is not the oil coming UP past the rings into the combustion chamber, it is combustion gasses getting past the rings DOWN into the crankcase (blow-by) that is happening at a faster rate than is normal on most engines and the excessive blow-by gasses are mixing with the oil and getting carried out and burned by the PCV system.I thought there were only two ways for a vehicle to use oil.
1. Burning it, which means it is getting past the piston rings. A software update is not going to fix that.
Based on what Jeep has said about it so far, I am tentatively willing to believe that they may have isolated the particular idling/running ranges and scenarios where this issue is most prone to happen and that maybe, just maybe, they actually can tweak the engine running parameters to avoid the sweet spot where this issue occurs the most at the highest rate. Won't cure it completely I'm sure, but if they could reduce it by a high enough percentage that cars which previously needed oil added between oil changes no longer do, that would be a win for them.
They may also hedge their bet with setting a reduced service interval or something along those lines as well. What I mean is, if the car previously was programmed to pop up a message for an oil change at around 7500-8000 miles (depending on conditions and use), maybe now they reduce that interval to 6500-7000 miles or something along those lines to try to catch people sooner, before enough oil has been burned to create a potential stall issue.
Reminder: The engine is designed and supposed to consume SOME oil That is 100% on purpose, its just not supposed to consume oil at a high enough rate to need some added between oil changes. A 2.4 engine that is using between a pint and a half a quart of oil between oil changes is running EXACTLY as designed and intended. The engineers made this trade to reduce internal friction to make the motor more efficient and more powerful, and it works when its implemented correctly. The issue is these poor folks who received engines with tolerances pushing the engineer's design spec too far, using way too much oil. Thats not the intention, but they DO intend your motor to use some amount of oil during normal operation. Thats probably why such a small 4-cylinder has such a huge oil capacity of 5.5 quarts. Its part of the design, but something went wrong when it was translated into mass-production for some percentage of these motors.Well, looks like I was wrong and seems like my 2019 burning oil as well.
This time I stretched interval between oil changes was doing at 8000 each time and this time getting closer to 10,000 kilometres and just check the oil and it’s at the bottom mark of the dipstick on level ground.
That’s not a good sign since it was just above half when did the last oil change.
