I have a 2006 F350 with a 6L power stroke. It has reached 350,000 miles and I am only getting around 400 miles per tank vs 500 to 600 that I used to get. What can I do to raise the mileage? Is there any maintenance that I need to perform (such as spark plugs) that would help?
Spark plugs???? OH BOY, first off read up on your diesel.
Here's some good reading materials.
If your injectors are high mileage there's not a whole lot you can do. Could try an economy tune to see if that helps.
