What kind of driving and how far have you driven?

Who changed the oil?

Was the filter changed?

You must reset the oil change reminder. It is in your manual. They cannot reset themselves. Or drive into quicky lube and tell them you will be in for the next oil change, if they reset the reminder and they will do it for free. They doem all day long so they know how on most every vehicle.

Either you (if you changed it yourself) or the shop didn't reset the indicator after the oil change.

Do this:

Turn ignition to On/Run (but don't start engine).

Press accelerator pedal fully three times slowly within 10 seconds.

Turn ignition Off.

If oil change indicator light illuminates when you start the engine, shut Jeep off and repeat procedure.

If it were me I would check the oil level and see what it looks like. If it is full and relatively clean I would reset the reminder as outlined above. If it as black and thick as pitch I would take it into the dealer as soon as possible to find out why.

Still would like to know how far you have driven and under what conditions.

It's not mileage based. It's duty cycle based so the mileage will vary. As you know it has to be re-set manually as was indicated.

I'm having the same issue myself now. Dealer did the oil change and I've only put on maybe 300 miles since then and just around town. I work from home so it doesn't even get driven every day.

Then it obvoiusly wasn't reset. Reset it and you will be good to go.

This is just what I do; in addition to resetting like the guys previously have mentioned; I change mine with full-synthetic Mobil 1 every 5,000 miles and its easy to remember the interval by intervals of 5, 10, 15, 20 etc. But I see you mention kilometers, but you may want to adapt a method such as that. FWIW.

I haven't seen this detailed in a post BUT I'm sure it matters (Sahara U Manual Pg 562) :

Based on engine operation conditions, the oil change
indicator message will illuminate
. This means that ser-
vice is required for your vehicle. Operating conditions
such as frequent short-trips, trailer tow, extremely hot or
cold
ambient temperatures, and E85 fuel usage will
influence when the “Change Oil” message is displayed
.
Depending on operating conditions, the message may
appear as early as 3,500 miles
(5630 km) since last reset.
Have your vehicle serviced as soon as possible, within
the next 500 miles (805 km).

It's a Big Improvement when a Sensor KNOWS the Style of Driving being done.

Thanks for the Re-Set info!

It's really not an issue. According to Chrysler the oil and filter must be changed at least twice per year regardless of the mileage. The Maximum change interval for non-severe duty is 8,000 miles. The oil change indicator is duty, not mileage based so it might come on in a few hundred miles or not until possibly thousands of miles. Regardless, twice per year or 8,000 MAX. It should be changed a lot sooner than that. It's only an indicator, a recommendation. It doesn't replace proper service practices or how you want to maintain your vehicle. If it comes on and you think you don't need an oil change just re-set it. Personally, I don't pay attention to it and change it when I think it should be changed based upon mileage and I check the air in my tires also.

i agree with you, but as an average indicator (service manual) isnt it 5000 miles? also up here in canada, we are considered a harsh environment, really hot summers, really cold winters. which can breakdown the oil.

I dont understand the duty based oil change message. My 2008 hemi ram would come on every 6000 miles. One time I changed the oil and reset the oil change reminder. Less than 1000 miles later, it was on again. The truck was driven the same as it always was.

I found out on this forum that the maximum oil change interval (in miles) may be set by the dealer. My dealer sets mine to 6000 miles. It comes on at 5,500 miles precisely every time. It goes in precisely at 6000 miles plus or minus.....every time. It has not deviated once in 60,000miles when it was set right by the dealer. It may trip early according to the "algorithm" based on you driving habits. My driving habits haven't caused that to happen yet.

I was also told that many dealers typically set the max interval to 1/2 the max recommended by Chrysler. For my jeep that would be 3500 miles and for new ones that would be 4000 miles. You have to be firm at the dealer and let them know that you want to maintain the warranty according to Chrysler and not according to dealer recommendations. The dealer will happily overservice your jeep and reap the extra income rather than do what the manufacturer suggests. I have seen this over and over at many dealers. You are in charge of your wallet, tell them what YOU want. My dealer doesn't argue this one with me any more because I went to Chrysler when they gave me false information and Chrysler called the dealer and reamed them for not giving me the correct information. They quickly gave me what I was asking for. And they haven't butted heads with me in some time.

So, do most of us use synthetic or standard oil for this 5,000 mile oil change interval? I'm using standard, but am considering switching to synthetic, and a 7,500 mile oil change interval.

Unless I have forgotten, you still have not provided documentation that this can be done. "What the manufacturer suggests" will in fact be different for everyone depending upon how they use and drive their vehicle.

Is the programming of the vehicle an open book? Or do engineers have to "reverse engineer" it. I'm saying that I have had it set both ways by the dealer. They can set it to the max interval of what Chrysler recommends for oil changes. I thought I was pretty clear. You can change it sooner if you want or if the oil change light trips early but the max interval is a setting. So far I haven't heard that the programmers that can be bought after market can set this.

It's not clear. If it was, it should be in the service manual or available via a programmer. So far it's only available in your Jeep.

The folks who make the programmers are pretty smart. I'm surprised they haven't found the place in the EEPROM that can be written to to change it. That is what I meant by the programming being a closed book. I guess they encrypt it too? Making it even more difficult to crack. I'm guessing that is why the after market programmers don't have it yet.
