mpg on a chevy with a duramax
According to: http://www.fueleconomy.gov/feg/bymake/Chevrolet/Silverado/2006.shtml ...17 Hwy/ 13 City.
This can vary if you like to just slowly cruise around, it could be better than what the manufacturer says, but if you keep your foot in it, then it will be a lot lower. You can buy performance programmers that have a "mpg max" option on them and it will raise your mpgs quite a bit. Not to mention they have a towing mode and performance modes. I, personally, prefer them because you can (with most) change on the fly.
