mpg

i have an 02 Trailblazer I6 4x4. I put a K&N filter in it and took off the roof rack crossbars. I drive careful but by no means like a little old lady and I consistently get 19 all summer long. In the winter it drops to about 16 to 16.5 but I have a remote start that my wife uses quite a bit. I've heard about bad mileage in these vehicles from a lot of people but I've gotten this ever since I did these two simple mods two years ago.

Oh it definitely has to do with the person behind the wheel as well... I usually average ~17mpg, however, when my Mother borrows the TB, it usually averages about 19...

I tend to have a bit of a heavy foot :D

Yeah I get about 17.5 and my sister just started driving and she wanted to drive my truck. It was really hard for me to let her drive, but I did and she got like 14. She gassed it everywhere. I was so scared riding with her. She will never drive my Envoy again.:no:
