could be the technical date is minute/miniscule enough between the oils to distinguish them apart and say one flows better than the other? I’m sure these guys have a valid reason for making that statement. it would make sense that not all 0w-20 oils are equal.

The owner's manual calls for 0W-20 oil that meets MS-6395 specification, and nothing but. Doesn't matter if you are operating it in the desert or the arctic. Thats the oil they say to use, thats the oil you should be using, period.

Like @Tripod said, the engine was built very specifically for the particular viscosity of oil it calls for. The engine oil is used as hydraulic fluid in narrow passageways managed by extremely high-precision timing of solenoids that influence intake valve lift and duration to make up the "Multiair" system.

You want your engine to run like crap? Go right ahead and mess with the oil viscosity, see how that works out for ya.

Want it to wear out sooner too because of improper lubrication? Try some randomly selected oil viscosity based on your natural expertise combined with something you read on the internet.

You want to give the dealership a fantastic reason to tear up your warranty and flush it down the toilet? Go ahead and mess with the viscosity some more. Tell them all about how you, in your infinite wisdom, decided that 0W-20 was far too "watery".... :pat: they will love that. They will love never having to work on your vehicle for free again, anyways.

The difference between 0W-20 and good ole 10W-30 is not really that extreme in terms of viscosity but with the minute tolerances they can build for bearings, the tiny passages they pump the oil through, and the extreme amount of precision computer control that is ultimately using the oil to vary intake valve timing and duration... nobody has any business messing with that. The most important thing to do for this engine is to keep the oil clean (change it and the filter often) and only use the oil its spec'd for. No funny additives or friction modifiers, just straight high quality synthetic oil.

but you should be able to use a thicker 0w oil.
i should have been more specific, 0w-20 oil. only stating not all 0w-20 oils are the same and should consider researching and understanding flow rates/tech. data behind each oil brand ...

I have to agree with Tripod and arudlang here not only for the reasons they posted but also things like hydraulically controlled timing chain tensioners and even correct lubrication for the timing chain itself. These things are not like old 350 Chevys or Dodge slant 6 that were not crazy picky about oil. In these engines the oil is not only used for lubrication but also as a hydraulic fluid that actualites different components. This means oil has to act in a given way at given temps so the ECM can control the engine accordingly.

Picked up a new Compass yesterday, made it 8 miles before it quit at an intersection.
Barely made it home. Wife’s not happy ?
Having to get your new car hauled back to the dealer stinks.
I hope they’ll buy it back or I’m stuck with a car my wife won’t drive

Please report back with what they find that caused this. Depending on what it is this might not be a major issue. We have around 10K on our Compass and it has never stalled/shut down like this. I feel like the majority of new Compass owners are very happy with their Compass from what I have seen on the internet. Sadly there are going to be problem vehicles in all brands. But if your problem was do to some small issue then it is likely once fixed it will be fine. If it were a major component failure then I would be much more concerned.

I can tell you my wife very rarely gets an attachment to a vehicle but it will be a sad day around here when the day comes to put our Compass out to pasture!

I purchased my Jeep Compass in June and am having the same stalling issue. I have had it at the dealership several times and the are useless and keep telling it is not throwing any codes so there is nothing they can do. Very frustrated and beginning the lemon law process!!!!!

It warms my heart to see that I wasn't the only person after all having problems with oil or other assorted issues. While not to brag, my RAM has had zero problems. That said, when I was at the dealer finalizing my compensation for the Compass, the whole service bay was full of new Compasses that were having the same assorted issues that mine was. God speed everyone.

Hello, everyone. My Jeep makes this odd whirring noise when it shifts into third, fourth, and fifth gears. It doesn't do it all the time, but I hear it at least twice a day. I feel like I can hear this noise best in the front of the vehicle and part of me even thought it could be something to do with the wheel. It only makes this sound when it shifts and it sounds comparable to a vacuum cleaner winding down after being powered off. Anyone else have this issue?

Thanks!
My 2018 Trailhawk is making this noise too

I have a 2018 Jeep Compass 6600 miles and 6 months old to me. Having electrical issues big time. Last one week has stalled twice with brake light coming on and parking brake coming on by itself (also shows blinking d on dash and blinking d on my shifter. Makes me put it back into park and shut off parking brake before it will move again. Huge safety issue as well as my nightmare. Not to mention other electrical issues, window going down when I have pushed up and radio turning off by itself. Now tonight the low oil pressure message came up for a split second. Am taking it into shop in a week but I am not hopeful. Anyone have any thoughts or suggestions on what might be happening. I would like to hear. I love the car but can’t deal with these types of issues.

The electrical issues are weird; I can't help with that. Your best bet is a good dealer. They may have TSBs on your problem that a local shop may not have.

As for the oil pressure light, I suggest checking your oil level. New engines can use oil, and it seems my Compass is using a lot. At 12,000 miles I'm getting 1500/qt. By now it should be broken in so I guess this is just an issue with the new Kittenfish, I mean Tigershark engine. Others on here have complained of worse oil consumption than mine. What I'm saying is your low pressure light might not be a fluke -- it might be telling the truth.

Thank you jasmine! I have checked my oil, probably a week ago now and although it was hard to see oil line appeared to be full and fine. It’s all confusing. At this point I will only take it to a Jeep dealer but I’m starting with a local one in my area not where I purchased. If I have to I will take it to them eventually.

2018 Compass

Bought my compass with 14 miles on it, at a little over 1900 it has stalled 3 times, given me a warning about low oil pressure that flashes and goes away and a light for service auto start stop system.

Can anyone confirm if a lot of these issues are tied to a production date range? We just got ours last month after the first one we were supposed to get was dead on the lot and then the instrument cluster didn't work. I bought some weathertech mats from a guy whose daughter had the oil loss issue and got Chrysler to buy it back. He warned me about the oil problems and now i see all these threads about it! I just checked my oil and it's down a little so I've gotta keep my eye on it.

Several people I've talked with tell me they have had theres built between 7/17-2/18 that have had there fair share of issues. That said, I don't think it's a specific production date range per say, just bad parts or workmanship. Majority of the 2017 models seem to be unaffected from what i've observed. Just the 2018's..

Help please

Hi folks,

I am new to the forum but would value your wisdom on this issue:

My wife and I leased a 2018 compass in September 2018. This is my fifth Jeep and I've always been happy with them. Since September, it has been at the dealer for 34 days (three visits) for the following problem, which remains unresolved.

At sporadic times, when attempting to start the car, the electrical features will turn on, but the engine will not even attempt to turn over. Then, if we attempt to turn off the car, it will not respond and the electrical items will remain on. When we open the door, the chime will sound and a message appears saying to turn the car off, but of course we can't. In researching this issue, I found the video below which demonstrates the same problem we are having. Unfortunately, no one an seem to figure it out. Any ideas or suggestions would be appreciated.

youtube.com/watch?v=UNeOhULryus

I see a recall (U87) for the voltage regulator causing no-start conditions, but our VIN isn't listed among the affected vehicles. Maybe an omission and perhaps that's my solution. I opened a case with Jeep but they've been unhelpful. The car has less than 2500 miles.

Thank you.
