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...

It's the first of 15,000 miles, 6 months or 500 hours. For most folks six months will be the trigger.
