Preventative maintenance
 

Hello All, 2007.5 6.7 Slt, 4dr short box.

I am running an h&s mini maxx with all deletes. I rarely tow and keep it on the stock setting. The main reason I did my deletes was for longevity, not power.

I run a quart of tcw3 2stroke oil with every fill up, run wix oil and fuel filters and change both every 3500 miles with shell rotella oil. I just hit 100k miles and am about to change my trans filter and replace with a wix as well.

I bought this truck for longevity, hopefully to get several hundred thousand miles out of it. I don't care about putting down 1000ft.lb's or blacking out intersections. Are there any other things I can do to ensure longevity of this truck and motor?

I have also replaced the fuel rail plug at the recommendation of other mini maxx users

Don't everybody dogpile on all at once!

I would say your doing a great job. Might be time to check your serpentine belt. I would probably go a little longer on the fuel filter maybe every third oil change.
I am curious about your H&S mini max. How do you like it and was it easy to delete unwanted monitoring parameters?
Just wondered cause of a thread I wanted to build on the newer dodges.
