Oil change interval Ram CTD .
I can't find the post but someone here questioned my 15,000 mile oil change interval , subject said his said 10,000 . I looked it up in my book and it does say 15,000 miles ! I can see some confusion...

My manual also says 15,000 miles for oil change intervals. I tend to change it out at 7500 miles, the severe duty cycle.
