My 6.4's oil life gauge is bonkers

[ductape]

What orifice does the oil life gauge pull its numbers from? It reads 85% but I have 7600 miles on the oil, what gives. If I followed it, the oil would be peanut butter by the time it's changed.

Do these trucks have one of those fancy oil conductivity checkers, or is the remaining life just a WAG?

The 'life' gauges are mileage based.

The 'life' gauges are mileage based.

On gassers it also depends on driving conditions

You must run a ton of highway? But still something is up as it is should never allow you to get over 16,000 km (10k miles) though

Not sure the true parameters. But my previous change I just did was putting me at 30% at about 5k. It was far enough for me.

I do a mix of mostly local 50-55 mph driving(rougher back roads) but mine does pull on the regular.

I liked the peanut butter statement lol. But in seriousness unless someone on the forum has real knowledge about how it should work and why yours would be letting this happen, I would be reaching out to dealership

I used the oil life meter for the wifes '04 Chevy. never paid attention to how many miles between oil changes. 145K miles and she still runs good with no motor issues.

On my new '21 Power wagon, I went back to 5K mile oil changes. It's easier for me to remember and I can do my tire rotations at the same time.

I have found that is easy to accidentally reset the oil life while toggling thru the evic screen. I literally just reset mine by accident the other day. hold the ▶︎ for a second and it resets

I would have to agree with jadmt, it seems like it accidentally got reset at some point.

At 7600 miles I would say it's due for a change, that's when mine hit 2% I think.

This must be it! I feel like I would have noticed that, but clearly not, since it's the only explanation. Thanks.

My local dealerships approach villainy, and it doesn't concern me enough to go that route.

Weird. Mine is at about 3k on this oil change and mine reads about 75% life left. It always gets changed early though. You must be really easy on it! As long as its working properly it takes into account many different parameters other than mileage to determine how much "life" is left.

Also I may just steal your peanut butter joke

I just change mine every 5,000 miles regardless of how I've driven it. Seems like cheap insurance to put off rebuilding the engine as long as possible. That's got to be a huge cost! Plus I have trust issues with computers telling me when go to things! lol

My company bought 3 new 2500's, my rig was reading 0% oil life remaining at like 2800 miles. the other 2 reached zero % around 3k miles. That's alot of extreme cold temp idling all night/day etc.

What I found more concerning is the amount of oil every one of those trucks burned, each one burned nearly 3 qts a piece before the oil got changed at the 3k mile mark...

 

[OLEJOE]

I have 4800 miles on mine and it hasn’t burned 1 drop of oil. Still always on the full mark.

From the owner's manual regarding the 6.4:

NOTE:
Under no circumstances should oil change
intervals exceed 8,000 miles (13,000 km),
12 months or 350 hours of engine run time,
whichever comes first. The 350 hours of engine
run or idle time is generally only a concern for fleet
customers

They are?

All manufacturers use some sort of calculation based on miles, load, idle time, temperatures, total fuel burned etc. etc.
