Most of the newer trucks average around 6 mpg. My 1984 International Cabover with a 300hp BC3 got 5.5 mpg and my 1985 Freightliner Cabover with a 3406 310hp caterpillar got closer to 6 mpg. My 1996 Peterbilt 377 got a lifetime average of 7.3 mpg with a S60 Detroit 500 hp.
Four to eight miles per gallon, all factors dependent.
The best mileage for a three quater ton diesel pickup truck is 15 mph. It will only change if you going on a stopping trip and you don't use a highway on a long trip.
Many of the new large displacement (15L) are running 5 -6.5 mpg at 80K some of the smaller displacement (9L,11L)get up to 8.5mpg at 40-60K
The 2010 diesel will not get good mileage. 14-16 on the highway and 10-12 around town. The gas (I assume your talking v10) will get you about 9-10 around town and 13-15 on the highway. If you want better mileage I would go for a 2011. The new 6.7 diesel gets much better mileage (up to 20+ on the highway in some cases)
NO. For a diesel this is very low mileage.
It depends on what type of driving you do. Hybrid vehicles tend to get the best mileage while driving in city traffic. The increase in mileage in the city is due to the increased used of the electric motor. Most hybrids (the notable exception is the Chevy Volt) will not use their electric motors while cruising down the highway. If you tend to do more highway driving, you will likely get better gas mileage by driving a vehicle with a diesel engine. Modern diesel engines run very smoothly, reliably, and cleanly. They also have the advantage of being less complicated than a hybrid vehicle while getting comparable highway mileage. City mileage in a diesel vehicle will be better than a regular car but not quite as good as a hybrid.
10 mile/gal We have a new 2011 F-250 diesel and it gets around 16 mpg avg, and around 19 mpg on highway.
The 6.9L IDI Ford diesel - 21mpg highway / 16mpg city The 7.3L IDI Ford diesel - 21mpg highway / 16mpg city The 7.3L Powerstroke Diesel - 20mpg highway / 16mpg city The 6.0L Powerstroke Diesel - 17mpg highway / 15mpg city The 6.4L Powerstroke Diesel - 16.5mpg highway/ 14.5mpg city The 6.7L Powerstroke Diesel - 21mpg highway / 17.5mpg city
It was only about 10mpg city and 14mpg highway. That was because of the diesel particulate filter (DPF). The truck emitted lower emissions, but got terrible gas mileage. If you get a DPF delete pipe, you can achieve 20mpg highway and 15mpg city.
My 2001 7.3 diesel gets 17mpg city or highway 50mph or 70mph. Towing a 10,000 lbs trailer mileage drops to around 13 or 14mpg.
Off road diesel is dyed but otherwise the same as highway diesel. The difference is in the tax. Highway diesel has a road tax on it
