your 2003 duramax gets 27.9 mpg?? bs
i can stand by my brothers 04 dmax and we are getting 25-26mpg. and that is hand calculated it is not impossible just some have better luck than others. just like them trying to doubt the guy on here that is getting 35mpg out of his cummins. the guy is just trying to sell some trucks.
