|lexington01||Mine came on today at just over 3500 miles. However mine is a 2012 that i purchased in September. It sat on the dealer lot for almost a year.|

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 seconds
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.
If the indicator message illuminates when you
start the vehicle, the oil change indicator system did not
reset. If necessary, repeat this procedure.

|Rob309||Now the light is on, how do I reset it. My comes on at 3,000 miles.|

The engine cycles also explains why some of you get the light earlier than others. If you go down to four low, there's 2.6 (or 4 if you have a rubi) times as many cycles per mile, as there is in 2 hi / 4 hi. Likewise city vs highway also factors in..
Again I must point out that duty cycle based is 100% certain; it's only me guessing that that correlates with the number of cycles the engine sees (the RPM integral).

|JKCliffDiver||Not much help I know... However, I change at 5K just to keep the same schedule as tire rotation. I've never seen my "change oil" light, or display thingy...|
|12-31-2012 03:37 PM|
I'm way over 30,000 miles and my light hasn't come on yet!
This is so cool that I can go this long without needing to change the oil. What a great rig!
Just kidding... My light just came on at 7500, but I've already done two changes. I switched to Mobile 1 at 5,000 and won't do another till 10,000 unless something pops up that indicates that I need another oil change. This is my 6th vehicle that I have done 5,000 changes with synthetic. it has worked well for me, so that is what I will continue to do.

|HRR1||What break in oil???|

Mine in the '12 came on at 9,400 miles. I already had an oil change planned for this week anyhow so I'll reset it at that time.
When my free oil changes from the dealership are gone in the spring, I'm going to start servicing the Jeep myself on 5K - 7K intervals.

|DJL2||I did not reset mine after an oil change because I was also curious...mine went off right around 7900 miles or so.|
|12-31-2012 11:08 AM|
I believe the oil light comes on based on the viscosity of the oil measured at the pump. My had break in oil that I changed at 3,500. I use Pensoil Silver and have had good luck using it in my 90YJ.

From the sound of most comments in this thread it looks like many are changing their oil too soon. The algorithms are based on very good data collected over decades of automotive technology. I doubt that any manufacturer would actually tell their customers to wait too long for an oil change. Warranty repairs are tough on the bottom line. Reliability issues are tough on reputations and future earnings potential.
Then again, when the Feds will bail you out maybe Chrysler doesn't give a shit after all.

Now I got it. No heart attack for me
|11-27-2012 01:05 PM|
As noted earlier, the light is just based on an algorithm. There are no sensors to speak off.
The computer uses a formula based on the number of times you start the engine along with some information about your driving habits. When it concludes the engine oil is probably toast, it dings. So if you don't reset the oil change indicator when you do a change (regardless of whether the light came on), the computer has no idea you changed the oil and will assume you have not.
No need for a heart attack.
The converse situation also true--if you never change your oil but simply continue to reset the computer every time the light dings, your computer will assume that you're running clean oil every time even as you rack up tens of thousands of miles on a single change.

Thanks guys !!
I'll have to read the manual.
I'll have to figure out is this also the procedure if I change the oil and the light did NOT come on. Do I go through this pedal pumping thing (resetting) even if the light didn't come on ?
The way I change my oils - I would have a heart attack if my oil light comes on.
|11-27-2012 12:17 PM|
Its the same with 3.6 too. I just changed oil on mine on Wednesday.
Oddly enough, my light came on that day after I changed it. Did the ol mash the pedal thing and it turned right off
|11-27-2012 12:04 PM|
But with the pre-2012 3.8 engines, you just turned the key forward two clicks (just one shy of starting the engine), depressed the gas pedal completely to the floor and completely up three times within 10 seconds, and then turned the key into the off position.
Not sure if the 2012s and onward are the same. I believe it is.

|Cold||Mine comes on around 2000 miles after i reset it. But it idles a lot and most of the time its in use its off road in 4lo.|
|11-27-2012 11:53 AM|
do you know how to re-set that computer ?
I am about to change mine at 5 K.
I did first at 600 ml, after that I went with Mobil 1 at 1,700, and now I am planning to change every 5 K.
It's easy to remember

How do those relate? School me

|DuneYeti||Mine came on at 3500, seemed a little soon for the kind of driving I did.|
|11-27-2012 10:47 AM|
|lolpetewtf||Mine came on yesterday at 8500 miles. I changed it around 3 but never reset the light. Oil still looks fresh. Mobile 1 15,000.|

|GREEN-MACHINE||i go by the oil ghange lite,,, did a change this past weekend,,, B-trip odometer ( witch i use to see how far between changes ) said 5200,, what is about normal for me,,, wifes pontiac goes about 4K ,,, she has very short trips and tons of traffic..|
|11-27-2012 10:27 AM|
I changed mines twice and both times I don't remember when I've change it! SO BEAT THAT!
(note: just broke 4000 miles a couple days ago)
|11-27-2012 10:26 AM|
It's an algorithm. The computer is constantly doing a little math formula based on the number of times you start the engine along with some information about your driving habits. When it concludes the engine oil is probably toast, it dings.
So if you don't reset the oil change indicator when you do a change, it has no idea you changed the oil and could go off at any time.
There are no sensors to speak off. If you drained all the oil, reset the light, and forgot to put new oil back in, the computer would think all was well as far as the oil is concerned.

|LuisCazarez08||I just did my 3rd oil change at 10500 miles on full synthetic and the oil change message came on today at 11200. Is there a sensor or does it go by miles.|
|10-25-2012 11:20 AM|
|jadmt||will they reset if they have not actually come on yet? I changed my oild at 1500 miles and went thru the motions of resetting but have no way of telling if it actually reset.|
