I usually don't post on here but I'm wondering what most of you guys with the 24 valve Cummins motors change your oil and filter at?
I currently have a 2006 Ram 3500 single wheel 4x4 4 door as my daily driver, I've tried to change the oil and filter between 3500 to 4000 miles, it has a little over 150,000 miles on it now.
I was told by the local dodge truck fleet salesman to change oil at 7500 miles, not at 3500 miles
The truck sits a lot now but I do use it to tow a 24 Ft. enclosed race car trailer with my bracket car in it, normal trace rip length is between 45 up to 850 miles depending on where I'm racing at.
I do a lot of local short trip driving also, probably around 90 % of its normal use.
All comments appreciated
