    I have a 2007 International 9200i with a caterpillar engine. I did the odometer calculation of the mpg and its currently averaging around 3.9. Is this normal? I am pulling an oil tanker pulling 7700 gallons per load on average. I did the oil, fuel, and air filter changes often. It's currently at 650k miles.

    No that is not normal at all. Hand calculate the mpg first, as the odometer computer is not always accurate. Also, do you have a boost gauge?

    What's usually normal mpg for these trucks? I'm pulling two loads (7700gallon loads) a day and refueling 200 gallons every other day.

    is it governed? do you stand on the pedal to go as fast as it will go all the time over any terrain until you get to the destination? if yes, then probably.

    The international 9200i's usually get about 6.5ish and the pre-emissions engines can get 7 or more. My freightliner gets 7.5mpg loaded with 45k. Does the truck smoke a lot?

    does mileage of the truck 650k decreases its mpg? Freightshaker, your truck sound brand new at 45k.

    Mileage has nothing to do with it unless if you don't follow up on maintenance. I had an overhaul done 180k miles ago and its at 1.2 million miles now. When I bought it, there was about 600k miles on it and even though it was low on power back then, i made no less than 6.5mpg loaded. Its a 2005 freightliner century

    If your making a cat tach over 1500 your burning uneccisaru fuel. I've drove them when they were mechanicals to the new ones, cat is low RPMS even for a diesel. Also the worst thing you can do for a cat is cowboy it, they like slow smooth shifts. Standing on it to get somewhere is a waste with a cat. I don't know what your platform weight is but that could have something to do with it. Also what kinda terrain.

    I've got a 425 mechanical cat with 2 million on it so 650k isn't a lot either.

    Exactly, that goes for other heavy duty diesel engines as well. Keep the RPM's below 1500 when shifting and you'll make some money.
