Oil Capacity

[Mofo67]

To start yes, I’ve read the owners manual.

I’ve owned a Jeep with a 3.6Ltr engine since we bought a Grand Cherokee in 2015. Currently have a 2022 Sport S Gladiator and a 2021 GC.
We recently moved so I had to find a new dealership to take care of our Jeeps. First service on my Gladiator was free since we are new to the area. Next I took my wife’s GC in, and a couple of weeks later the Gladiator for another service. I get home and look over the work order and it shows 6 quarts of oil. Go back and check the GC, yes 6 quarts of oil. Check the complimentary oil change and 5 quarts. Check the owners manual and past receipts and yep, 5 quarts.
I call the dealership and the service writer said sorry both were a mistake and they would refund for the extra quart of oil from each service. Transferred me to the business manager who tells me the oil capacity is 5.5 quarts and they charge everyone for 6 quarts. I mentioned the owners manual, past service records including the complimentary one from their dealership. He insisted that I was wrong but would refund the 2 quarts. Sent me a check for 1 quart and hasn’t returned my call requesting a refund for the other quart.
Anyone else heard of these vehicles taking 5.5 quarts?

Yes, I’m finding a different dealer to take care of my service.

Should be 5 quarts in the 3.6 JL/JT, the JKS used 6. Can’t say about the GC as I’ve never had one but I’d imagine it would be 6 as well.

Correction…. I checked the owners manual of the GC and it is 6 quarts. I had previously only checked the owners manual of the Gladiator.
FYI - past service on the GC, records note 5 quarts and it’s never seemed low on the dipstick.

A lot of discrepancies (variations) in the information online even if you go searching for it….
2024 Owners manual…. 5.0 quarts

Did you check the dipstick after the service? Does it appear to be too full?

If they use anything over 5 quarts, even just 5.1 quarts, you will get charged for six. Most places use a bulk oil dispenser, they are not pouring from quart or gallon containers.

If you are going to use the dealer for oil changes, look into the Jeep Wave program, or the pre-paid oil change packages that are available. It is usually less expensive that just paying for a single drive-up oil change service.

I was alarmed as well. On my first Wave oil change the service order said filled with 6 quarts. I checked some threads here and found it not such a big deal to run one quart over. The dip stick looked a little high but I agree that when the techs dispense the oil if it goes a hair over 5 quarts the meter will read 6.

In service fill capacity is 5 quarts. There is some mention of 5.7 quarts in official Jeep media specification sheets, but that is the initial engine dry fill requirements.

Just another example of a less than ethical dealer employee operating under orders to squeeze ten or twenty bucks out of every customer than walks through the door. It is quite nearly standard operating procedure. Add this to the fact that the oil change guy is always the newbie that still isn't trusted to tighten Lugnuts. I get it - everybody has to start somewhere, but they ain't going to start by stripping out my drainplug by calculating that really, really tight is better than really tight.

LOL - right, another conspiracy. Yup.
You've never worked in a shop and don't know any of them personally, I take it.

Why is it that we've never once had a problem with any service other than one time, at a dealership that didn't have experience with the then brand new JT with the lower oil capacity than Jeep people were used to. They overfilled ONE time, that was it. I brought it to their attention and they did a FULL new oil change (stupid, that cost them!) instead of simply drawing out the extra (simple process, takes only a couple of minutes)

Never a stripped or broken anything. Yeah, we do take advantage of the free wave changes.

One nice thing about Jeep engines, up to and through the latest Pentastar....Their design standard is that the engine can pass all tests and meet all performance metrics from 1 quart low to 1 quart overfilled. So there is a safety margin built in. In the case of the Pentastar Upgrade in the JL and JT, MANY of them are running around with 6 quarts in them because the dealerships don't know their own product. And while it is not ideal, it is not causing any harm, either.

I remember when the JL came out people were losing their minds over dealers putting 6 quarts in. I asked a friend who was on the original Pentastar design team and he told me that standard and not to worry if it was overfilled.

It's a silly thing that they can't seem to get this right at many dealerships.

You might want to take a mulligan on that one. I would offer a response, but your point, if there is one, is not decipherable.
