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...

I change at about 7500 on average as that is the 6 month mark for me. Mine doesn't get a lot of use - my motorcycle is way more fun to commute with.
