I think you're right, unless you do a lot of towing or a lot of idling, high rpm driving, etc. I'll have to verify, but I think mine is showing 4900-ish miles on the current oil and 39-ish% life left. About 3200 of that was towing, so around 3/4 total driving. At that same rate, 0% would hit at around 8k-ish miles.
That makes sense to me as well , but if this is true .

Then my OLM Is broken LOL , I'm clearly in the 2nd cenario ( although I'm a very non agressive driver and don't tow super heavy ). I just changed my oil at 6,700 ish miles on it and my OLM said I had 41% remaining , rough math puts me at about 12.5k for the OLM to read 0% [emoji1303]
I feel I'm in both #1 & #2 more so #2 , either way the OLM projection woul be over 12k ?

I agree , I'd say folks would be fine going 10-12 k on on a high quality synthetic oil with a non towing , no offroading ,daily driver grocery getter , but not with whatever some dealerships and jiffy lube stores are using .
I did my math in my head that's was my approximate.
I agree... not trying to one-up ya. I just still had the pen & paper out when I saw yours and did the calc. I think it does work on a sliding scale.

This was at the end of my 3rd oci. I had towed about 6500~ of those miles.

On the reset I've read several times to do it the way you said there and I've done it like that before , but I typically just do it with the EVIC controls on the wheel while running just after I change the oil , it zeros out right then and restarts the miles since last change ....I have the 3" non premium cluster .
Hummm, I tried that on mine the first time I changed oil and it wouldn't let me do it that way, it actually had a message that said do it the other way. Must be different years or difference between 1500 and 2500. Mine is just standard express so I wouldn't assume too much premium stuff.
Well, I can kind of answer that question. I didn't change my oil, but kept running it 4k miles past when it said 0%. It did not reset, just kept saying change oil every time I started it. That was the 12k heavy towing oci I posted the UOA on. It was basically 4 trips from the east coast to the midwest and back while transporting vehicles in my enclosed hauler last summer.
What year is your Ram , 1500/2500 , 5.7 or 6.4 , do you tow ?
Mine is a 17 1500 5.7 and the only time I've had it in tow/haul mode was just playing with it to see how it changed the shifting. Haven't towed at all. Haven't worked mine at all. Maybe the olm does take into consideration how much you're in tow/ hawl mode. That would make sense since it tracks run time and conditions and all that. Now if it would only monitor the actual condition of the oil.
