RAM Cummins fuel filter change interval

Hmmm, I had mine changed at about 100k miles. The service tech at the dealership said I was probably OK cuz I mostly stayed in warm climates.

Here is what I was told by my friends dad who worked on diesel engines for 30 years. Change the fuel filter at the beginning of Spring and Fall. I have done this will all my trucks. If I put more than 9,000 miles on it between that time frame, I will change it at the 9K marker.

What is the proper fuel filter change interval for a 2012 RAM Cummins? The owners manual seems to side step the question. Dealer wants to do it at 15k miles. Since they are a little pricey, I don't want to do it any more often than necessary.

My 2011 HO the same truck as yours is 15K. I just do the air filter at the same time. www.genosgarage.com is a great place to buyMopar/Fleetguard filters. Be sure to get the nano net fuel filter, 4 micron.
