MPG question 6" lift 35-36" tires

[94cwbyup]

I have a 94 silverado and I would like to install a 6" lift and 35" or 36" tires which almost requires 4.11 or 4.56 gear ratio i assume. what kind of MPG or is it GPM can i expect with this combination? by the way it's a stock 5.7L with a 4 speed automatic trans. and 4 wheel drive

I have 96 Suburban with Rancho six inch and BFGs 35s and get 12mpg city/15highway. It also has headers , exhaust and intake.

Well, not the same engine or body style, but I have 9" of lift and 35s, 4.56 gears and I get about 10 in town and about 14-15 on the road. I also have a CAI, programmer, TBS, and performance exhaust.

After I did my lift I drove to the coast and back, I got 423 miles out of 21 gallons of gas.

you can get any where from 15-20 mpg. all depends on your driving style if you can keep your foot out of it when it when you can. go with the 4:56's. im in the same perdicament as you and all the info ive been told im going to go for the 4:56's. all the people well except fr drumm14 i dont know what hes got. but the suburban is going to differ alot from you bc the weight. and the air displacment. and and masterfox has a newer body stlye. with the 5.3 so its going to slightly differ as well. but your going to range from 15-20 you can get anywhere in that area with that setup. the size and weight of your rim is also going to be taken into consideration a low weight alloy rim will get better than a steel rim. a 16" rim will get better than a 20" unless the 20" weighs less.
