I don't think they have the weight carrying ability I need, lmao j/k

 

haha it looks likei am average....and i though mine was bad 19 mpg woot!!!

 

i drive 900 miles a week for work in my blazer and i get 23.8mpg on almost every tank.....it's 2wd 4.3 1996 and thats with 87 octane....anyone know if these blazers will run on e85?

 

Haven't "Officially" added my input. In about a month I am going to be taking a 831 mile trip from here at Fort Riley to TheUpper Penninsulaof Michigan. I figured that would be a perfect time to computer my MPG.

 

I've also been toying with swapping in a 5 speed and some 3.08's in the rear

 

You'll get decent highway mileage, at least...

Blazer is too heavy for 3.08s around town... Even with a 5 speed... A 2wd S10 would be good, with those gears, though.

 

They can but it will cause the check engine the to come on. The O2 sensor detects to much oxygen in the exhaust. If you really want to you can get away with 50% E85, 50% regular gasoline. You'll probably need to change your fuel filters more often because of the alcohol dissolving the crud in your fuel tank and lines.

 

E85 refers to the percentage of ethenol... You'd want E50, lol.

I don't think the Blazer would like E85...

 

90% of my driving is in town and it's just a 2wd thats why i figured 3.08's but maybe 3.42's with a 5 speed would be better? would i really notice any difference?

 

Yes.

3.08 gives you less acceleration ability. You might be okay with a 2wd... but a Blazer is still kinda heavy for that...

My 4x4 Blazer with 3.42s on factory rubber could do 18 if a babied it.
