Fuel Guzzler

[imhoppster2]

I drive a 2006 Mack Granite CV713 Quint axel dump. It has an AI375A engine with Allison Auto. I knew when I bought it that the auto would not get the mileage that a manual would get

but I didn't realize 4.5 to 4.75 was going to be my fuel economy. If I am standing on it all day I would expect those numbers; but I have made an effort to try and lower my speeds to

increase the economy with no sign of improvement. A friends mechanic recommends a new set of injectors that will increase the fuel economy as well as performance.I guess my question

is will this work? Has anyone else experienced this?

We have lots of CV dump trucks around here. With the AI engine the usual average MPG is 5.2 so your not off by much.
