Fuel mileage is as much a component of the driver's ability to squeeze more MPG's out of the truck, the climate in which the truck is driven (flat, headwinds, etc.) as the type of engine. What you're failing to realize is that Joe blows truck might be driven in conditions that greatly affect fuel mileage compared to your conditions. Just one underinflated tire or 2 more stoplights would have a significant impact on MPG's
If you took all the types of truck diesels made, inserted them in the same body style truck, with same tires, wind resistance, weather conditions, same stretch of road driven by a computer, my bet is the IDI and early Cummins get the best fuel mileage.
Think about it.
Needless to say, the newer trucks with their higher outputs & more emmissions controls will suffer in the MPG dept.
