Truck in sig...17 city, 22 highway

 

Truck is a extended cab 4x4 5.3ho 4.10s with stock 265/70/17 tires and i get 13 mpg city on bad gas(no name gas stations emergencies) and 14.5 when i fill up at shell or exxon and highway at 75mph is at 17 with cheapo gas and 18 with good gas.

 

11.1 6.0, 232/234 595/598 112, 3800 stall, 410s, svo 30s, chrome 20s right now with a mix of city,rual and highway im seeing 18mpg

 

If I drive like ****** grandma at 65 with cruise on 23 MPG.
75 MPH I get 17.5-18. Anything over 80 and I can watch the gas needle move!

 

best of 21.1 hwy at 70 on cc

 

i can get anywhere from 14.5-24.. hahah , thats either pulling our 16' tandem axle trailer with 4 4x4 4wheelers goin way to fast. but usually its 17-18 in town running it. i can baby it and get 24 but thats not fun... im im not in a hurry and just cruising around. i usually get 20-21.


so anywere from 14-24 for me.. mostly 18

 

i jsut got 11mpg. mostly city driving with quite a few WOT blasts for tuning purposes

 

06 Sierra 5.3 4x4 no mods 16 city 18 highway at 65-70 mph. I figured it would get at least 17 18 city 20 highway but i was wrong AGAIN.

I have to convert mine to US gallons, so if done properly its best has been 19.2 MPG highway at like 50 MPH in mountains(only tested once since mods), and maybe 13.3 MPG in town. Towing has seemed to get beter recently at 10.8 doing from 65 MPH to 75 MPH and 16,000 LBS GCWR.
