Post up

 

I get a regular 13.8mpg around town and when I went to the mountains I got about 17mpg running about 75-80 mph. Right now im running 285/75/16 tires. Ive got a couple mods and I just ordered my headers so im hoping for a little bit more ot of it.. Ive found that if I baby it or drive heavy footed it dont change.

 

2003 gmc z71 ext cab

15.6 no matter who, what, were and when.
Bone Stock.
13.5 in the winter.

 

I get 17 with the 315s.

 

17mpg with 315!! is that around town?

 

Man mine sucks and i flat bone stock. Any suggestions on what i can do to improve on the gas mileage

 

Ummmm. What size tires, tire psi, regular mantiance done? How do the tires wear?? might have a slight drag if there wearing bad from alignment.Really dont know how you could only be getting 11mpg. What is your milage when the low fuel light comes on?

 

All my oil are changed when suppose to be, trans case, transmission, axles and motor. All i run in engine is mobil 1 full syn. Plugs have been changed, everything is stock as far as tires and suspension. The only mods are a K&N filter. I remember brand new the sucker got 18.1 on the highway. Now only about 15. Maybe it time for a new one or maybe it likes to drink gas like i like to drink .

 

12 in the city 17 on the freeway (75-80, ac on)

 

Well since ive done my mods and drivent it a bit, I got an average of 16mpg. Im happy!!
