Please help me increase my MPG
I just bought a 2006 Ford F-350 Powerstroke extended cab short bed truck used from the Ford dealership. It's completely stock (63,000 miles on it) with the exception of a front end leveling kit and 35" tires.
When I bought it, I replaced the air filter, oil, and oil filer. I filled it with diesel and added the appropriate amount of Diesel Kleen as suggested to me by my brother who religiously uses it in his Powerstroke.
I made sure to run the first tank of diesel out without hauling or towing anything and to be very light footed with the accelerator. When I refilled it, I calculated the gas mileage by hand and was getting an average of 10.8 MPG.
This seems like very low MPG to me. My friends and family who own diesel trucks average about 50% better fuel economy. Some Fords, some Dodge...
I took it back to the dealership and they said nothing is wrong with it in any way but I don't trust them because they seem to have their own agenda.
Surely something must be wrong? Please help me get better Mileage. I've tried the normal things such as tire pressure.
Any suggestions would be greatly appreciated. I am very new to diesel ownership and a little worried as MPG is the reason I sold my gas truck.
