    i was wondering what was the best mileage you can possibly get out of a diesel

    with a chip possibly.

    i would think it would be with the duromax????

    My LB7 Duramax gets about 21-22 mpg unloaded at 65-70 mph. Loaded with a 7x18 and about 4k or so on the trailer, at the same speed get about 15-16 mpg. Not too bad.

    04 D-max (dads)with a utility body full of tools and a crane about 10k all the time runs about 18. A friend who owns a mobile repair business has a 7.3 ford p-stroke gets about 14 and his 6.0p-stroke gets about 12-13 both run loaded all the time.

    04.5 Cummins just logged 18.5mpg in CITY driving...best it has ever gotten in the city. Was on #1 diesel with powerservices' diesel kleen. Usually city driving gets it around 16.5-17.5. On the highway it'll get from 20-22 running 75. These numbers are unloaded. Throw 12k behind it and your talking 11-12. Auto trans; 40k miles.
