Not bad for a BIG motor,,, my 5.9 dodge gets like 11mpg average of course that one is a 93' with 214K on the clock.. part of why I bought an 02' sonoma.mitchntx said:My 2500HD has an 8.1 ...
Actually, I like it. fuel economy is reasonable (13-14mpg) and it goes like the wind (but not getting 13-14mpg).
I would like to put an aftermarket cat-back on it ...
