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...

Do any of you have your oil analyzed?
It would be interesting to see the results, as to the condition of the oil. I change my 2001 5.9 at 10,000 miles, test always come back good.
I have samples analyzed on my 7.3 PSD every other oil change, but haven't yet done so on my Ram. But now that I'm out of the 36K warranty and into the powertrain warranty, I may go ahead and start doing them.
Nobody on that forum should be changing their oil at 15K. That's basic EVIC data, which is comparable to the most vanilla driving scenarios. 7500 or 10K should be the limits of folks who use their vehicle for more than commuting on open highway at 60 MPH everyday.
