Out of every excavator that I have ran, the volvo beats them all. It's by far one of the best machines to run. It does good on fuel, ever since we've had the thing the fuel gage has always show a 1/4 tank less than what you really have. So that makes it seem like it burns it quick but in reality it's only used 3/4 of a tank. I can say that the daewoo does get more hours on a tank than the volvo. you can almost go 16 hours of steady digging with a tankfull on the daewoo, that pretty good I think.
