Oil Sensor questions

Ok, so I asked a couple questions last time I changed the oil (IN DECEMBER!!!).

I am approaching 9,500 miles since my last oil change. I have called the dealer. They are insistent that I not change it until the sensor indicates.

This made me nervous so I contacted Chrysler. They indicate to not go over 8,000 miles. They were insistent that I not "reset" the oil indicator (the whole key to start 3-pushes on the gas thing). And that I change the oil again when the light indicates (even if it is really really low mileage).

I am confused by this stupid thing and am seriously debating just going with 5k interval like I have always done.

There is no harm in changing your oil "too soon". However, damage and wear could result from changing it too late. It's your choice.

8000 is less than 9500 or "until the sensor goes off," so I'd change it now. For warranty purposes I'd change it next time around +6,500 - but after that I'd go back to every 8000 as it says in the book. I'd consider documenting that your dealer said not to change the oil at 9,500 for your records.

However, there is absolutely no need to go to 5000, this isn't the 1960's.

Call me old-fashioned, but I've always changed mine in new vehicles at 1,000, 3,000 & 5,000. Break-in periods are important to me for the long term life of ANY moving parts...overkill is a good thing!

Todays motors build sludge. I would never go that far. They run alot hotter than in the 60's. todays motors run in the 200+ range. Out here In Hell pluss off road alot, can be very dusty. I change it 3500 no matter. Yea it cost more. I do not care. pluss my DiC goes off at 3500 anyway.

I change every 100 hrs of operation. Since most drivers avg about 50 mph on a long term basis that would be 5k miles. For me 100 hrs accounts for long off road periods that can be as low as 2k miles between changes. It also comes from my experience with heavy equipment maintenance

There are very few scenarios where early changing is detrimental (older flat tappet engines need zinc and overchanging washes zinc off the cam so you NEED to wait until 3K and use high zinc oil). Personally I would not go over 7500 on a change on these newer engines...

Engine hours is a much more sensible indicator of use than mileage.
For those interested, the JK has an hours meter built into the trip computer. Its worth monitoring.


I'm surprised the OP's OCI never went off. Makes me wonder if its even working.

I have always wondered if old-time habits like pumping the gas before starting the engine cause some folks to accidentally reset their OCI.

I follow my OCI like I follow my GPS. That is right up until it stops making sense.

I have no idea why the OCI never went off. Back in December, I changed the oil "early". Hit 5,000 mile mark and my wife was taking a long trip so I figured I would change it. About half way into the trip, she called and said the Jeep was telling her to Change Oil. She got home and I "reset" the thing.

I guess my big question now is if I change at 5,000 do I reset the sensor, or do I have to wait for it to indicate a change is needed before I reset it? Chrysler says to not reset it. And insists that I change the oil again when the sensor goes off. This seems really odd...

And, the dealer is still insisting I not change it yet.

Always reset it after an actual change. That way it CAN remind you if it needs a shorter cycle next time. Chrysler is giving you a standard response that covers your butt even IF it assumes you are air heading it. (Be surprised how many people swear they changed it and didn't or swear they did not reset the minder and did - even accidentally). Just like taking medicine - read the "if you forget a dose" instructions!
