my 06 lbz gets 16-17 city highway driving. from my house to work is 22 miles one way. the best tank was 21 mpg road trip to vegas. :drink
this is my first diesel. but coming from a 03 chevy ext cab 4wd 4.8 motor with a 6 in fabtech susp lift. this is way better mpg for me.. and a hell of lot more power to play with :rof
