My Jeep dealer had an issue with overfill, and I advised the service writer in advance. FCA specs are 8.4 quarts, but based on what I’ve read on this forum, 7.4 quarts may be the magic number. I think it has to do with the fact that a Jeep Wave oil change does not include dropping the supercharger which holds at least a pint, and the dealer doesn’t wait for 100% of the old oil to drain.
Even admonition was unsuccessful in preventing an overfill, and I was the first 7:30 customer, I don’t know how many THs were made, but you would imagine at least one tech at every dealer would be well versed with this forum - especially oil changes. I wasn’t out till 9:30. I would not be comfortable driving with the level above the high mark on the dipstick since it wasn’t high when I biught the vehicle, and the Wave partial oil change does not include the supercharger oil. Ask them to drain it. You can always top it off. Thank you. Eric
