Oil change indicator......

[Feel for life]

Question to all in here............

We have a few options when comes the time to change our oil....we either get advise by some sort of chime and indicator that it is time to change our oil or we go with the milleage required in between oil changes.......

So my question is .........Is there a way to reset the OBC to recognize the new time frame and/or milleage that needs to be recognize by the On Board Computer?

I for one go with synthetic......so technically I'm good for around 8000K........not 5000K like regular oil.......so how to do this so the chime and indicator reflect the new reality?

Awaiting some answers........

Well how you Feeling today?

I am sure you're away that the oil change alert either on the dash with or without EVIC is programmed and duty cycle based. By that the computer monitors between oil changes various parameters in the engine and outside.
Temperatures, length of drive(s), speed driven taking into account for city/highway etc. Winer condition with a lot of short trips and/or city driving with cause this to alert for a change quicker.

Whenever this alert does come on its too long in my opinioin. Having said that and if you're already doing it the old way, millage based then switching to the computer alert would give you a more extended and safe extended change cycle. Whether you'd want to use an large oil filter (posted details before on them) may be advisable. There is no way WE would be able to change this threshold since there is know way for the computer to sense the difference in dino and synthetic oil and I doublt there is a sensor that monitors oil condition either. A lot of Synthetic oil is modified dino oil, a molecule is modified synthetically allowing the manufacturer to claim its synthetic and I believe Mobile start doing that years ago from details on another forum when I had another vehicle but thats another topic entirely.

I've pulled this up but its on as details as it could be and there is text out they on the parameter used but I have not been able to locate it at this time.

remember, it's not just the oil that determines the interval, but the oil filter also. your oil filter might not be effective in that range.

now, with that said, the 2011+ is rated for 8,000 miles (~12,800 kms), so take that for what it's worth.

That posibility would be under optimal driving conditions and almost certainly hwy miles. Odds the ChangeOil will pop up long before that especially in the cold/cooler weather. Contaminents built up and acid within the oil and as good as the oil and protection might be they're not removed from the fluid.

If you drove coast to coast in a week or two putting on that millage you'd be ok with few starts and hot cold cycles. But thats not the case for 99.9%

Run synthetic but still change the oil and filter. Few of us would entertain having their engine rebuilt. But all would change there oil if that was clear would eliminate a rebuild. Its the cheapest solution.

3,000 mile oil changes are antiquated rules. the new pentastar V6, both I4s, and the hemi now got 8,000 miles for oil changes. my compass first came on at 3k for the first, and has been coming on every 7k-8k after that. but i also run synthetic in it, as i do in all my cars.

Mine came on at 4000 miles (not sure what the oem oil was) then again at 7000. That sucks for the money of Synthetic. Will have to try a different type of oil than Castrol Edge and filter I suppose and see if it improves. My wife drives this very easy, no lead foot.

The brand/type of oil used will have nothing to do or have an effect on when it comes on. If for example there are a lot of short trips and in cold weather it was shorten the oil change millage. Longer drives and fewer stop and go instances will extend it. There are a lot of factors computed by the computer and oil type is not one of them.

7000 miles is a lot for one oil change interval. If you're getting that I would not go further unless you not keeping it in 4 years. Someone else will inherit the engine problems

based on what data? the new oil change intervals are based on countless hours of testing, and they wouldn't give those figures out without being able to back them up. the 3,000 oil change interval is a 50 year old practice. engines and oils have come a long way in half a century.

I changed it at 4000, then again at 7000 - so I only got 3000 out of the second oil change. Conventional oil is rated ay 3k while Synthetic is 5k minimum I would say. Trust me, I will change it everytime it tells me, but do I believe it actually knows... I doubt its really that precise at all.

Ok I think I understand what happen. You likely did not reset the oil change alert. The pedal proceedure is in the owners manual. I have it written on a blank page near the back where I write the mileage and date of change. I believe around P117, 3 down ups in 10 sec as I recall slowly.

Dude, not sure why you are reading other things into my post. If I never reset the mileage, it would continually ping at me until I did. 4k for the initial oil change and 3k till the second. End of story.
Just putting it out there to see what others have been getting.
