Great fuel economy though. Haul 20 loads of mud in a 10 hour day and use 30 gallons of fuel. Keep in mind every load the Detroit is at full tilt for probably 10 minutes during loading and making water adjustments to the mud.
yep Thats what I love about the old 12V 6B Cummins. 165 hp, 350 ft lbs, not fast. But unloaded with a 5 speed and 3.55s, can get nearly 30 mpg if you stay around 50-55
