Is a slushbox, or an automated manual trans (with or without a T/C, vs clutch).

If a slush box, it probably isn't to far off. Still not good. I think in should do better.

On site in a quarry that's about normal. We have Kenworths ranging from '94-'06 models with 15 speeds, 18 speeds, 18 speed Autoshifts, and various CAT and Cummins engines from 400-575 horsepower..... and we're getting about 4mpg in the quarries and during city/country road deliveries. Even on the highway loaded we're only seeing about 5mpg tops.



I put on 174 miles today, 150 of it was highway and the rest was on site, around 10-15mph running around, and I topped off with 47 gallons of fuel for the day... . '97 Kenworth T800 455hp 3406E and a 15 speed Roadranger running 105,500gcvw... that averages about 3. 7mpg, which is completely normal for our fleet.



Hope this helps,

Dan
