"Oil Life" indicator?

[rickinAZ]

I'm a little compulsive about oil changes. In fact I've changed my oil eight times in 24,000 miles over five years. My most recent change was less than 800 miles ago yet my "oil life" indicator reads 32%. The recommended change interval is 10,000 miles. What gives?

Where did you see that?

Did you reset it?

The oil life indicator should be an algorithm part of that algorithm is time.

Do you reset it each time you change your oil?

It’s a duty cycle based system. More stop and go, or off-road driving will shorten the interval for the oil change. Unless you drove extreme off-road trails for 800 miles it’s likely, as multiple people have already said, it was not reset after the last oil change, or there’s an outside chance there’s an issue with that diagnostic.

I believe the owners manual mentions 10k miles or 12 months as the absolute maximum interval for doing an oil change.

you people change your oil? jesus ya'll must be rich.

once every 4500 miles or every 6 months. do forget to reset the oil life monitor

Change the oil when the computer says to, typically about every 10,000 miles per the owners manual. For the 392 it’s every 6,000. Others do it more often than this, but they are just throwing their money away but to each their own.

Here we go the good old debate… there really is no one size fits all answer because of driving circumstances and use cases. So I don’t think people are by default just throwing their money away. Some are… some are not. Here’s another killer question:
Does it matter whether I go with Mopar oil or another brand?

I’m not sure why there is even a debate. Everyone thinks they are smarter than design engineers, but again to each their own. If those changing it at more frequent intervals than the manual states are not then testing the oil to see if it even needed changed then I can certainly argue they are throwing money away. I like factual data to make decisions.

News flash: A guy who bought a Jeep says we’re throwing our money away

engineering doesn't decide oil change interval.
bureaucrats/bean counters do.
that came right out of the mouth of a Stelantis engineer.
we were speaking of a 5.7 at the time. he said change it at 5000 miles with 0 w 40 and it will serve you well.
he said engineers don't have any say in oil specs or change intervals.
he went on to say , change your 392 every 3000.
they want your engine to last just long enough for a extended warranty of usually 100,000 miles to expire.

8 in 5 years isn't what I'd call compulsive... It's only slightly above bare minimum.

Everyone thinks they are smarter than design engineers,

1. Engineers are not smart. Most of them are average corporate ladder climber and do whatever their boss tells them to do, and write reports on whatever computer simulation yields. Smart people wouldn't stay in stalantis. lol
2. This is not about smart, is about knowing the cause. Especially behind the scene CAFE plays more roles than technical optimization.
