I know there is a tone of Gas Mileage Posts but i want to see an updated one on your Lifted blazer. I plan on getting one lifted about 2-3 Inches on 31's

Thanks guy's

 

With everything i have done i think its.....12-15 give or take...mehhhh

 

Mine gets 20-22 stock except a cai. I might hold off on the lift after seeing those numbers.

 

Don't forget that Warthogdriver is running on 33"s which will definitely affect the mileage. I'm getting around 18mpg (70/30 hwy/city) with a t-bar crank, body lift, and add-a-leaf (4" total) on 31" tires with 3.73 gears.

Warthogdriver, did you ever regear your truck? What gears to you have?

 

no...i have stock gears in it.
i have to get my summer car (project) back up so i can have blazer down to do work like a re-gear...plus the cash. i have no idea how to swap out gears.

 

im getting 17 city 18 almost 19 highway last time i checked

i dont have a cai yet but i do have a 2 inch lift with 31s 3.43 gears

 

Mine came stock with 31's, does that count?

 

When you're looking at mileage, there's a ton of things that come into play. One of the biggest is your right foot. If you're going with slightly bigger than stock tires, that's going to reduce your city mileage, and *may* increase your highway mileage slightly. Going up to 31" tires with 3.42 gears will decrease your mileage, and if you go with even bigger tires without changing your gears you'll decrease your mileage even more.

When I first put on 31" tires with stock (3.42) gears I lost 1-2mpg in both city and highway, but I also live in a fairly hilly/mountain area, so there isn't a lot of flat highway cruising. When I swapped out my axle and diff for ones with 3.73 gears and 31" tires I get around the same mileage as I did with factory height tires because the final drive ratio is almost the exact same as it was from factory. I swapped out the axle and diff because I got a great deal, and it was easier for me than trying to change the gears alone.

 

My '94 came with '31s when I bought it, and would get 13-15MPG but it wasn't running 100%..maybe 85%. That was with 3.42 gears, and I did not correct the calculation for the different tire size. Just about everything that could leak in CPI unit was leaking, too. When I had it running 95% (still had a poppet with slight leak-down) and back on stock size tires I was back at 19-20MPG keeping at 65 on the highway
