The first oil change was actually around 6700 miles. I can give you the exact mileage if you like. It's a 6.7 diesel, and the oil life left was zero. I had just completed a 2500 mile round trip drive to Key West and back give or take, and towed my 10000 lbs boat probably 2000 of those miles. When i got back, the oil change light was not on, but came on a couple of months later and I had it changed. Probably around Sept of 2022.
I'll probably just go ahead and change it. I want to switch to full synthetic anyway.
Thanks for the replies..

Had mine changed and the OLM reset today at 10,500 miles which is about 700 or so short of next oil change due.
All the Oil Life Monitor is, is a clock. The time can be weighted if you are just driving, or towing, or idling. When the time runs out the clock goes "bing" and sets the alarm. Someone failed to reset the alarm to the proper time, which like a real alarm clock can be done at any time with no special tools. It can also wake you in the middle of the night if not done right.

I have had a 2011, 2015, 2018 and now a 22 6.7. The 22 is the first 6.7 that the OLM is telling me to change the oil every 3k miles or so. The prior trucks never came on at the 5k mile interval I would change at. Did they change the algorithm for 22? My driving style has not changed from 2011 so I am a little confused.

If the dealer changes it, just make sure before you leave the lot that the oil change percentage is reset. Sounds like they didn't reset it when you last had it changed. It's likely a new or low-level employee performed the job, and skipped what should've been a standard step, perhaps.
