    Whats the worst fuel mileage you've ever heard of?

    Have a driver try to tell me the truck started using excessive fuel. Truck has an MBE4000 @ 450hp with the speed set at 70MPH. With the trip he did I calculated the mileage to be less then 2.5MPG. I already checked the obvious places for fuel, antifreeze (not even sure if possible with MBE), oil, and leaks.

    I'm not stupid I know it the driver either moonlighting with our truck or selling fuel.

    I'd still like to hear some stories from you guys of the worst fuel mileage you've ever heard of.

    Most of our trucks get from 4 MPG to 5 we haul a gross weight of 120,000lbs on average and most of our trucks are single turbo cats.

    My darn truck was showing 3 mpg the other day when I WAS OVERLOADED!!! I usually get 6.5-7 mpg and I didn't have near the 120,00 you had.

    Sounds like an income suppliment. Sad that some folks do that stuff.

    A buddy of mine had an old Silver 92 Detroit turned way up and he said he was getting 2.5-3mpg back in the 80's but fuel was cheap!! Rolling lotsa smoke!!

    Did this just happen on one trip, or the last couple? Its pretty hard to fire someone for steeling unless you catch them on video or with witnesses. Might have to just have a "work slow down".....

    Good luck Kevin, it's a real slap in the face when people do that.
