Has anyone noticed their gladiator burning oil

[JET_83]

He's talked about the number of months in other posts, saying it was too long.

I can't see the OP giving us a whole history on oil changes, just saying his last two to show a reference point. If I said mine was changed at 20,000 and again at 24,000 - who is going to assume I went 20,000 before the first change?
Further, if he went 32K he'd have been empty, out of oil, and there's no mention of any oil added prior to this time. Safe assumption - it's been changed before.


Well, jet or whoever, here ya go - I'll have to dig out my certifications and get scans or pictures of them, I've got my fuel system cert out in my shop.............

Congrats, bud!

I’ve owned the jeep since new. The manual says oil changes every 10,000 miles. I do mine every 5,000-7500 at the most. Always used pennzoil synthetic. Dealership did the first few with the wave program. Truck seems fine, same gas mileage and no weird noises. Just thought it was strange it was a quart low within 4,000 miles of oil change

I’ll have to look and see where the manual says every 10,000

So, would FCA view the burning of one quart in an oil change period in a properly maintained vehicle (assuming it is) a warrantable repair or that the engine is “broken”??

The answer is no. It is not warrantable and engine is not broken.

When discussing my engine’s internal coolant consumption of 10 ounces per 10k kms oil change since my first oil analysis @ 1000k kms and subsequent oil changes, (6) total in 32k kms all showing glycol contamination, my service manager said, “your engine isn’t broken therefore Chrysler won’t fix it”.

He then gave me an example of a customer that came in with their jeep “burning 5 quarts of oil per oil change period” and Chrysler said “the amount being burned falls within their acceptable window of usage”. The engine, according to them was not broken.

Maybe the cold winter and snow pushed the motor more then normal. When I changed it I put 5 quarts. I see some people put 5.5 quarts so maybe that’s my issue

You didn’t see any oil spills on the ground or anything like that while it was parked, maybe you can do so inspecting to see where the leak is at if that’s the case

That’s insane!

Causes of excessive oil consumption - I could go grab my Dana/Perfect Circle diagnostic book but think I can pull most of this from memory -

Valve guide wear
Valve seals worn, aged, etc.
Head gasket
On engines with the intake also being the valley cover (legacy V8s like the SBC) a bad intake gasket
Rings - stuck (sitting, varnished, etc.)
Rings - loss of tension due to overheating
Rings - worn/broken (oil change intervals exceeding manufacturer's mileage recommendations in our case 10K or less depending on conditions)
Detonation damage - cracked/broken piston, broken ring(s)
PCV system

Side effects of excessive oil consumption -
smoking, messed up converter, detonation (ping from detonation), carbon build-up in the chambers, on valves causing excessive compression ratios, valves not seating, potentially burning.

and of course "and more".

And there ya go - perfect oil change intervals, not any too long at all! Just about right for most drivers especially with a good mix of city and highway miles. That's about where I sit with oil changes.

I run 5 quarts and it shows full. I never see it down to the low mark. 5 quarts would not put it on the low mark, unless there's a stick issue.

No I don’t see any leaks. Definitely would show up in the drive way.

Thank you OP for clearing that up. Good for you in keeping up with the routine maintenance of your JT. Being you have lost 1 quart of oil in less than 5K miles, I would take it to the dealership and have them run some diagnostics and see what they can find. Losing oil is not normal.

I can't think of any manufacturer that would admit it's too much after 4,000 miles, but that doesn't mean it should be down that much.
Some go so far as to say a quart in 2,000 miles is normal - but that's very excessive in my experience unless it's a legacy V8 - my 390s and 360s would indeed drop a quart in 2,000 miles, under extreme use, even a quart in 1,000 miles but then look at how they are designed!

 

[CrazyCooter]

5 quarts brings mine to the full mark - is that what you mean? 6 quarts is above full.
Does yours not read full after 5 quarts? Mine does. It's sure not a quart down.
5 quarts goes into mine each time.

IDK on mine because I don't have a 3.6L, but the 2018 JL I just got done servicing for the 2nd time was just above the add mark with 5qts...........

I remember a thread a while back where there was argument as to whether you should fill to the full mark OR just add the printed spec amount? Then later should the stick read low, should you add an estimated amount of fill to the full mark? (There were also people that recommended measuring what came out and refilling with that exact amount? :Knuckleheads: )

Through my career, I have always filled to the full mark knowing full well that there will be some loss over time assuming the person runs that oil change all the way out till the max recommended interval, PCV valve condition, operating conditions, and overall engine condition.

2 ounces of oil on a surface will be VERY noticeable! There are 32 ounces in a quart - 32 ounces could be spread to almost the entire parking spot if you tried.

 

[Mr._Bill]

I’ll have to look and see where the manual says every 10,000

The Owner's Manual states not to go more than 10k miles or more than one year between oil changes. It does not give a recommended change interval, just the oil life monitor.

why would any use of oil like that even be considered normal with low miles and them not warrant it though, makes no sense.

Go ahead and check it out if you don't believe me. Consumer reports, cars dot com and the owners manuals in my collection of car and Jeep owner manuals over the years - many of them state the same thing. Even BMW today says the same.

I disagree when applied to MODERN vehicles, but it made total sense with old piston and ring designs, and other differences.
Today, IMO, it would be absolutely totally unacceptable to go through a quart of oil in 3,000 miles.

@CrazyCooter - check this out -

For references, mine received exactly 5 quarts of oil about 4 weeks ago so it's got a few hundred miles on it - look where the oil is on the stick with FIVE (5) quarts of oil, not 5.5 quarts, not 5.3 quarts, 5.0 quarts - I even aimed the end down-hill so oil wouldn't run up higher on the stick, you can tell by the drip forming on the end to the right.
