so what kind of mileage are you guys getting with similar trucks. i have an extended cab short wheel base 2000 z71 and i get 12-13 on mostly open road. truck has always been serviced properly and well taken care of but it does have higher miles on it.

i was wondering what everyone else gets cause this seems awfully low to me.

 

What size tires do you have on it?

My ECSB when it was stock with the 5.3 would get 19 consistently with my mom driving it back and forth to school. but it is 2wd.

 

I probably get similar MPG haha

 

i only get about 14 mixed.

 

man, i havent got that bad of mileage since i towed the mustang from the track. mine usually hangs around 16ish sometimes its alot higher if i just cruise.. but it doesnt do that much. ha

 

I've never actually calculated mine, and I really don't want to.

 

i get 12 city and 20-21 on the highway.... Gotta love a loose verter... Mine is a 4.8 thou..

 

mine has been anywhere from 10.5 towing to 23ish cruising.. mind you i did get 26 one time, but i dunno if i can be easy enough on it to try that again.
First weekend of the 4L80E swap i put 1100 miles on her and averaged 21mpg.

 

I get 16.5 when i hammer down on it all the time. If i stay out of it i get 20 city/highway mix

 

I get right around 20 mixed driving, alot of 45 mph cruising to work and whatnot. straight city driving usually around 16 not hammering on it
