The manual says once a year if you don’t exceed the mileage limit.
Frequency of Oil Change
My wife drives my ram to her work up the road, probably about 15 miles on average a day. Is there a timeframe I should be looking at on where I need to change the oil? I'm nowhere near the 7500-10k mile checkpoint for an oil change and it's been a couple months, how often should I be changing it?
Thanks for the help, first time post and I'm a little new at this.

Thank youThe manual says once a year if you don’t exceed the mileage limit.
If you really want scientific evidence of when to change the oil, you need to send in a sample to a lab for testing. I've been sending my samples to Blackstone Labs (I'm not affiliated with them, just been using them for 20 years!) since I got my 2014. I started off changing the oil at 10,000 miles, per the manual, but their test results now have me going 30,000 miles on an oil change. I change the oil, air, and fuel filters when I change the oil.My wife drives my ram to her work up the road, probably about 15 miles on average a day.

Do you use a 10k rated filter and change it every 10k?
If you are asking me, Vern, I use an OEM filter and change it every 30k miles.Do you use a 10k rated filter and change it every 10k?

IMO you should change your 10k rated filter every 10k regardless of whether you change the oil. If it’s Blackstone labs is checking your oil they will confirm this. There have been at least three pictures of collapsed oil filters from running them too long on this forum. Two of which were mine.
oil and filters are pretty cheap compared to a new but can't get it engines.
Definitely great advice here and little reason not to at least change the filter. Anyone who has changed the oil/filter on these engines knows it's very easy. Access is simple to the cartridge filter on top. You don't have to drain all the oil like on many engines.IMO you should change your 10k rated filter every 10k regardless of whether you change the oil.

I hear you guys. I've got over 220,000 miles on my truck but maybe I need to reconsider the filter.

As you can see, I've had some longer oil change intervals based off time, but not mileage. I do a lot of severe service driving (short trips, towing, idling, etc.). So far, the UOA has come back good, but the oil is definitely losing its additive package according to the UOA. Lots of short trips and frequent regens has shown to be hard on the oil over a 6+ month period of time. I added the AFE deep oil pan in February earlier this year. It increased the oil capacity to 12 quarts. Although not completely scientific, the viscosity and TBN were slightly better in my last interval even though I drove an extra 1,000 miles on the interval. Since a lot of my driving falls under severe service conditions, I'm now documenting idle hours and driving hours as well. There are my last 4 oil changes.My wife drives my ram to her work up the road, probably about 15 miles on average a day. Is there a timeframe I should be looking at on where I need to change the oil?

Oil and filters are cheap, adding additional filtration is cheap, engines are expensive, soot in oil is an abrasive, the oil additive package is designed to deal with this to a point. Certain things can happen to the oil that can precipitate the soot out of the oil = BAD. People that talk about personnel use vehicles running the oil to its maximum soot carry limit are stupid and cheap.
You want your engine to live a long trouble-free life? Keep your oil clean and change it often.

still under warranty?. if so, change before 10K miles or 1 year. Heavy hauling, I'd cut it in half,
