Traded my 2500 for 3500

Yes... for the diesel oil changes are every 15k miles. I still think their chart for fuel filters is a bit of an overshoot. It certainly won't harm the engine changing them even more often, but it sure will hurt the wallet for no reason.

I agree they are over change fuel filters, I know of one 2022 who fuel filters went 21 months an EVIC showed 30% life left when changed, in my old 5.9 I could go 30K between filter change without any problems, but then I also used quality 5 micron filters from Baldwin...

I only use Fleetguard/Mopar filters, but I routinely go ~30k before replacing and my EVIC still shows 20-25% life left. This looks like a little bit of a sales tactic thrown into the manual. The Cummins rep in our area used to tell us at our shop that 30k was severe duty, but they just made it the standard for everyone to be safe.

They didn't do that with the transmission though... as far as I know on the 68RFE it's still 60k severe duty and 120k standard duty.

The hemi is basically just as much for an oil change...at least for some that use redline, or HPL oils for the finicky hemi to try and make the lifters last. Also, the 5.7 recommends 89 octane, and in my area it is as much or more than diesel, so I guess it is how you look at it whether the gas is cheaper to maintain...could be more!!

under 100$ for oil change on my '19 laramie 5.7 and I only run regular fuel except a couple times towing on really hot day used midgrade.
