    I have a quick question. Roughly how many mpg does a Gmc K3500 dually, with the 454 in it get?

    I don't think I ever heard anybody with a big block claim more than 10 mpg. Dually or no.

    You won't see over 12 max on the highway. 8-9 aorund town and even 7 with a lot of hauling/towing.

    I talked to a guy at the gas station that has a GMC 2500 DMAX........told me he got 16mpg pull'n two horses back from PA to VA.

    The older 454's got bad mileage. The vortecs. Buddy of mine has one, single rear wheel and it gets 4-5 around town and 7-9 on the freeway. yuck. I remember last year I plowed with it and that thing would use a 1/2 a tank of gas on a parking lot (small). Go diesel, I get 18mpg pulling my trailer with the new nasty fuel.
