thanks coolbreeze, it was built in 2014 so I will change.
saw someone say synthetic. I always used in on my 5.3. do I need to on the diesel. didn't know they made it. might as well change fuel filters also. can I do it or should I let the dealer.
You can do it, and much cheaper than the dealer. I get all my filters at Cummins. They sell all the Fleetguard filters for our trucks. You may have to buy a new fuel filter housing with replaceable filter the first time but every time after that, all you need it the paper filter. Buy the oil where ever its on sale at. I keep an extra fuel filter under my seat also.
