2.4 Multiair oil consumption
Bought my 35K mile 2016 Cherokee Latitude from a Jeep dealer a little of 3 weeks ago. That 2.4 Multiair with the 9-speed does a pretty nice job, although I was originally leaning toward the 3.2 Pentastar, thinking that the 4 wouldn't cut it after reading various test reports.
My concern now is oil consumption issues with the 2.4. One of the first things I did after buying it is open the hood and check things out. Not cluttered up - can actually see the ground in a few places. Pulled the oil dipstick - oil at the full mark - and pretty clean. Filler cap says to use 0W-20 oil, guessing only synthetic only comes in that grade. Since purchase, I've been reading various reports about the 2.4 being terrible on oil consumption, but not all of them. My thought is that it might be a quality control issue at the engine manufacturing plant. Since I don't drive it much, I asked my "better half" if she's checked the oil lately. She hadn't, so I opened the hood and checked. Oil down to the "add" mark - 1200 miles since the "full" mark! Not good - thinking I might have one of the bad ones - never had a vehicle that would go through oil like that - not even the 912 inch ISX Cummins diesel in the big truck I make my living with - it only uses a quart in about 4000 miles. Added a quart of 0W-20 Mobil Super Synthetic oil to bring it to the "Full" mark. Odometer showed 36801 miles. Oil meets Chrysler MS-6395 specification, as required in the owners manual. Took 4 time-stamped pictures of the odometer reading, dipstick before and after adding oil and the oil bottle of the oil added. Figured if I'm going to have oil consumption issues, I better verify everything. I will keep you posted on how things go from here. Welcoming any comments also... |
Not normal and not good.
My boss had the same problem on his limited 2.4l engine. The dealer told him it was normal and when he asked for documentation on it the dealer replaced engine.
Sorry to give you the bad news but you've got a bad engine. Search for a recall |
No recalls on the 2.4 Multiair with oil consumption issues. From what I've read regarding FCA and other auto manufacturers, the policy is 1000 miles/quart usage is normal, which I believe to be a B.S. policy...
Almost all the miles since I bought the Cherokee have been local miles. Took the Cherokee on a 200 mile trip earlier in the week. The next morning I checked the dipstick - the oil level hadn't dropped any. Could be that running the car local without the engine oil reaching full operating temp might be an issue, especially with the 0W rating. Another thing I've been thinking about - when the oil was changed before I bought it, the dealer shop may have put the wrong grade in the engine. I've seen all kinds of shop techs in my life, and it wouldn't surprise me. The dealer is primarily a Ford dealer, with Jeep being their secondary make. Oversights do happen... |
Technical Service Bulletin 09-007-15 states that acceptable oil level use is 1 qt. for every 2,000 miles for the first 50,000 miles. After that point, the acceptable use is 1 quart per 750 miles.
Here's some more from that TSB: Some engines require more time than others for the oil to drain back into the crankcase. The vehicle should be allowed to sit for a minimum 15 minutes, after the engine has been shut off, before taking an oil level reading. To ensure an accurate reading, the temperature of the oil should be close to the same temperature as the previous time the oil level was checked. Under or Over Oil Fill after an Oil Change After an oil change, verify that the proper amount of oil was put in the engine and that the oil level on the dipstick is not above the full mark or below the add marks.Refer to the Owner Manual or Service Information for information on recommended oil quantity. Correct Oil Type Verify the vehicle has the correct oil. Refer to the Owner Manual or Service Information for information on recommended oil viscosity and quality. Crankcase Ventilation System Verify that the Positive Crankcase Ventilation (PCV) system is operating properly. Blockages, restrictions or damage to the PCV system can result in increased oil use. Oil Dilution (Fuel and Water) On vehicles that are normally driven short distances, less than 5 miles (8 km), especially in colder weather, unburned fuel and condensation generated from cold engine operation may not get hot enough to evaporate out of the oil. When this occurs, the dipstick may indicate that the oil level is over-full. Subsequent driving on a trip of sufficient length to enable normal engine operating temperature for 30 minutes or more, in order to vaporize excess moisture and fuel, may give the customer the impression of excessive oil consumption. Causes for Oil Consumption: Aggressive Driving Aggressive driving and/or continuous driving at high speeds with high RPM's will increase oil consumption. Because this may not always be an everyday occurrence, it is hard to determine exactly how much the oil economy will be affected. A higher rate of oil consumption is normal for vehicles equipped with manual transmissions that are driven aggressively. Aggressive means; operation at high RPM (3,000 RPM to redline), with frequent use of engine braking (using the engine to slow the vehicle). Vehicles that are driven aggressively may consume engine oil at a rate of up to 0.946 L (1 quart) every 805 km (500 mi). This is normal for a vehicle that is driven aggressively. No repair is necessary. This driving habit will require the owner to check the engine oil level at frequent intervals, to verify the oil level remains within the recommended operating range. Oil level should be checked every time you get fuel. Towing or Heavy Usage Towing a trailer will increase oil consumption and may cause oil consumption to fall below the normal accepted rate referenced in this bulletin for an unloaded vehicle in a personal use application. Large frontal area trailers will further increase the work required from the engine, especially at highway speeds increasing the rate of oil consumption. Engine Wear Piston scuffing, excessive piston-to-wall clearance, tapered or out of round cylinders, worn, damaged or improperly installed valve guides, seals and piston rings will cause an increase in oil consumption. Engine Temperature If an engine is ran at overheated temperatures for more than brief periods, oil will oxidize at a faster than normal rate. In addition, gaskets may distort, piston rings may stick and excessive wear may result. Verify that all cooling system components are in proper working order. |

The OP hasn’t been back For over a year. He has probably dumped the Jeep by now..... . |
It's what cafe emmisions dictates.
Over my life of 22 years in the automotive industry I've seen many oil issues. The problem isn't the engines, it's not the engineering, it's fuel economy ... And no one feels like checking there oil... Ever.. and adding oil... If they don't want to come in for 3000 mile lube service .. nothing wrong with cars.. high end cars put 9 quart oil pan on 2.0 turbo and no dip stick.... Think about it... So stop fussing.. check your oil regularly and add some when needed... You don't complain when you fill gas tank every week for 50+$.. so adding a quart of 0-20 or 5-20 at 3-4000 miles cost 8$... Time to get with the reality of modrn day engines... I have alot more info and specifics but I gave a great over view for all you with issues.. any questions ask and I'll respond.

Tim Are you saying it is normally for a engine to use that amount of oil? I have a 2018 Jeep Cherokee Laritude with 27,300 miles on it. At 25,000 miles I had to add a quart of oil in between oil changes. Up to that point I have not had any oil usage. In that 2300 miles 3 quarts of oil have been added. I am currently doing a dealer consumption test. |

Update
Could you update? I just purchased 2019 with 3000 miles on it. Now reading about oil issues. Thank you

Thank you. Hopefully I dont have issues.

Folks, that why I got rid of my first 2019 Cherokee and went with the 3.6L (which has its own issues but they are well documented and the dealers have no options but to fix, replace or refund). Now, the 2.4L has a very specific way to "check the oil level", which is documented in the manual and is not "how we did it back in the old days". So, please make sure you are following the "check oil level" instructions or you will get a "false low reading".
That being said, if you still think your Jeep is "consuming oil" as the dealer would say. Have the dealer do an "Oil Consumption Test". Mine took a month and showed nothing wrong but I kept at them with "feeling unsafe in the Jeep, because low oil will cause the engine to stall out (which mine did twice, without warning)" and they started "offering to extend the original warranty, including Powertrain, to 100k" and finally offered to exchange the Jeep for the 3.6L version (paid half of what the original difference in the sticker was). So, if you can get the dealership of offer something, it better than dealing with this on your own later. |
My 2019 manual has no oil check instructions specifically for the 2.4 engine, it’s the same for all three engines. BTW, how did you get the dealer to install a custom 3.6 engine in your KL? They only offer the 3.2 from the factory.....
