i have a 2001 silverado single cab short bed z71 with the 4.8 v8. i am debating get a lift here within the next few weeks. i would like to get a 6 inch lift with 35s. but i also do a lot of driving. i currently get an average of about 15 mpg. i am just curious how much mpg you guys have gotten before and after the lifts.

lifts give you better MPG due to weight distribution and leverage

On my old NBS I was on 35s and 4:56s with the 5.3 and averaged 13mpg combined

If youre worried about MPG, buy a Prius.

I got 15 on my last 400 mile road trip. 35s, 12", and 4.88s.. goin' ~80 on the interstate.

 

[2LoNoma]

I get about 17,18mpg goin 70mph with 35's

 

[Chris.]

I got 8 in my 93 tbi 350 with 3" and 33s. no cats, 10 series race flow, etc etc.

If you want mpg, buy a chrysler 300.



I know where you can get one cheap.

I average 13-14 MPG with my '07 (3.73's til I go back home)

I've never checked my '99

 

[el semental]

it would be 1 or 2 less miles than what u get, atleast is what happen to mine which is what u got.

9.5" FTS , 36" tires, 4.88s, ECSB, 5.3L:

11.5 city, 16.5 highway, 12.5 mixed.

 

[Megalos]

'05 ecsb, 5.3, 9" lift, 34" tires, 4.56 gears with some heavy accessories and I can get 15 mpg on the highway on a good day. I don't bother with calculating city mileage because I know it'll be bad.

 

[lousieg55]

Get a bb tune that gained me like 2 mpg easy

 

[badassgmc]

25mpg

3 inch BL with 285/75/16s with 4.10 gears, drove from nashville,tn to atlanta,ga. and back. filled up 3 times. $210 in gas! im definitely getting a diesel. (i did do 90mph the whole way but still)

atl to nashville round trip is app. 500 miles

Gas would be at most I say $2.50/gal there

so 210/2.5= 84 gals

500miles/84 gals = 6 MPG


Something is wrong there :imo

I figured gas would be cheaper than that over there. Its only 2.80 over here in overpricedifornia. But ya, even doing 90 something is wrong.

Cant be wrong cause i did 70-75 mph (which is right about at 2k rpms) from Miami, Fl to Tampa, FL and spent $120. And im on 285/75/16 with a 3in Bl and 3.73 gears. Bottom line is bigger tires and rims, even with lower gears, is going to give you worse mpg. Every truck is different from what it seems.

 

[Country Boy]

Anything over ~75 and I can watch my gas gauge drop. Something about having the aerodynamics of a brick going 90 down the interstate...

 

[lousieg55]

I have never gotten worse then ten, even on 42s so something def wrong.

 

[Shorty01GMC]

i might get about 10 on a good day, downhill with the wind at my back
