New 2025 Ram 2500 6.7 cummins

[Dragon44]

Good evening!

Recently bought my new diesel truck and absolutely love it. Getting to know my owners manual and see recommended oil changes are 15k miles. My question is does that seem really long? Or am i getting old and the times have changed and it will be fine? Or should i cut it to 10k, 8k or 5k? I plan to do oil analysis in the future but wanted to know yalls thoughts. Thanks for the responses and God bless.

No, you're not getting old,....well, maybe you are, but that is a long OCI in my opinion.

These long OCI's are all about the cost of ownership over a certain period of time. They stretch these maintenance intervals out to lower the cost of ownership. It's all about business and profits. It has nothing to do with you or the engine's best interest.

How is the truck used? Heavy towing? Casual driving?

i like to keep diesels inbetween 7k and 8k miles. they have large sumps.

What is the rough service interval? That’s what I would use…

I'd go with a 40 grade & run it 15k then. If you're towing severe duty & Ram specifies a shorter interval then go that route. Sounds like you do plenty of highway driving so it'll be fine. Sump size is sufficient for those types of intervals. Go with a "full synthetic" though if you can.

Mine gets changes in the 7K-10k range typically.

HPL 5W40 CK4 with a Donaldson DBL7349 up to 10k or 1year most times I never hit 7K it’s a 10min oil change on these things and oil is cheap in the big big picture of things.

10k - if that’s 2X/year - space it out for nice weather and get a good look around under the truck …
