Thanks Tom. My understanding is that it is both duty cycle based and milage based. If duty cycle doesn't trip it, milage will. I do not, at present, have access to a dealers programming module. The service interval was changed upward for the 12s. I am interested in what other MY 12 owners are seeing for milage intervals when their warning trips.The system is duty cycle based not mileage based so your question is irrelevant. Your dealer should have reset you oil change reminder when he changed the oil.
Daggo is correct. It is not time or mileage based. And, it is only a recommendation. You still are supposed to change the oil twice a year and no longer than 8,000 miles for a 12. It seems that there are alot of individuals who totally rely on this system to do maintenance (oil changes) when Chrysler clearly indicates that you shouldn't. The E-85 issue does not apply to a JK. Notice they indicate "may". Mileage by itself will not trip it nor will time. We all still need to be conscious of when we need to do general maintenance.Thanks Tom.

.Oil Change Required
Your vehicle is equipped with an engine oil change indicator system. The “Oil Change Required” message will flash in the EVIC display for approximately 10 sec- onds after a single chime has sounded to indicate the next scheduled oil change interval. The engine oil change
indicator system is duty cycle based, which means the engine oil change interval may fluctuate dependent upon your personal driving style.
Unless reset, this message will continue to display each time you turn the ignition switch to the ON position. To turn off the message temporarily, press and release the MENU button. To reset the oil change indicator system (after performing the scheduled maintenance), perform the following procedure:
1. Turn the ignition switch to the ON position. Do not start the engine.
2. Fully depress the accelerator pedal slowly three times within 10 seconds.
3. Turn the ignition switch to the LOCK position.
NOTE: If the indicator message illuminates when you start the vehicle, the oil change indicator system did not reset. If necessary, repeat this procedure
Parameters for duty cycle programmed into the controlling computer code I have no knowledge of.Change Engine Oil
The oil change indicator system will remind you that it is time to take your vehicle in for scheduled maintenance. Refer to “Maintenance Schedule” for further information.
NOTE: Under no circumstances should oil change intervals exceed 8,000 miles (13 000 km) or six months, whichever occurs first.
Stock oil? Get it changed.On my 2012, it just came on at 3500. I drive very short distances and it's damn cold here in PA.
Should I wait until 8000 or get it changed? Nervous.
Thanks!
8000 is the MAX you should wait under perfect conditions. No one drives under perfect conditiions. Short trips in cold weather are hard on the engine, that's why it came on early. Change it now.On my 2012, it just came on at 3500. I drive very short distances and it's damn cold here in PA.

I don't think we agree. I change mine every 3k. I was merely pointing out that 8k is not what Jeep recommends. It's what Jeep says that you should not exceed.Like Alexia I use Mobil 1 Synthetic also but I agree with Tom on the 8,000 mile max. There's a reason Jeep recommends that limit so I'll try to adhere to that standard. And tough driving conditions may warrant earlier oil changes. This is an area in which there will be many different opinions.
I just got 1002 miles and changed it today . I will change it again at 4000 miles I do every 3 thousand miles and will also rotate tires . my driving is short stop and go miles . and to add I never did a easier oil change then this jeep I didnt get dirty at all ! :dance:i heard you should change your oil and oil filter right after first 1k miles. im at 920miles, is this true?? :hide:
I always do it. My belief is oil gets dirty quicker from engine break-in.i heard you should change your oil and oil filter right after first 1k miles. im at 920miles, is this true?? :hide:
