I would run a couple of used oil analysis on it to see how much dilution and viscosity loss is occurring. At the same time, the gas smell is not a good way to measure dilution--even my MPI 3.6L can have a gas smell to the oil, but the average for my dilution for the past 55,000 miles is 0.9%. Most OEMs use 2.5% as the limit and there have been 2.0T engines on this forum with 3.7% in only 4K miles.---For Anyone Searching for Facts---
- Started with brand new 2021 JL 2.0 Turbo with 14 miles and crystal clear oil.
- Planned first oil change at 1000 miles, however still being crystal clear, I waited.
- Oil stayed clean up to 2000 miles taking on a hint of darkness, decided it was time to change.
- Life happened and didn't change until 3000 miles. At this point the oil was black with a strong odor of gasoline
- Thought; "this can't be good" and did some research.
- FOUND OUT >These engines (DI/Turbo) are known to dilute the oil with gas.
- THEREFORE > Will be changing the oil and filter every 3000 miles.
- BONUS > The only oil I found to publish the approved oil specs for the Jeep 2.0 Turbo AND was easily available was Pennzoil Platinum 5w-30.
I would never go 10K on a turbocharged, direct injected engine given the fuel dilution and viscosity loss that is inevitable. You are wise in your plans.I'm not overly worried if I go a little longer, but it is a turbo engine, so I do play it safe...
I have it changed once in the spring and once in fall... I average about 1K miles a month.
Over the course of ownership, it's about an extra $200 to change between 6/7.5k mile instead of waiting til 10K. I'm comfortable with that.
^^^ This is how most modern iOLMs work.I doubt the onboard vehicle oil monitors are more than either an LED measuring how much light passes through the oil or more likely they work like the MPG meter and use time and rpm and just do statistical math without measuring anything.
The automatic oil change indication system, at least on my 4xe has a TON of parameters you can monitor (which i'm doing) and trying to track down the parameters which cause FORM (fuel oil refresh mode) if anyone has J-Scan they can look at a lot of the variables. It way more than an LED, but it's not like the PCM would lie about stuff like that. But i'm curious look at the video below and tell me?I doubt the onboard vehicle oil monitors are more than either an LED measuring how much light passes through the oil or more likely they work like the MPG meter and use time and rpm and just do statistical math without measuring anything.
Lol, if I was you, I’d insist to be there for your next oil change, otherwise I know who won and it ain’t you my friend.My 2019 JLU was bought with an extended warranty, which at my dealer, gave me 8 oil changes, 12 with Jeeps free oil changes.(I know nothings free).
I also insisted full synthetic oil for my Jeep, which at the first change(2,000) my dealer said; no it requires semi-synthetic, I told them, NO, it was part of my extended warranty and if not, I don't want the warranty, guess who won?
Full synthetic, 5w-20w changes, at 3-4 thousand mile. The dealer told me that they use Pennzoil, per manufacturer!
