Just curious, but what is the generalMPG on everybody's blazers? I get 16 MPG with my 1995, while a co-worker with a 96 blazer gets 15mpg. Anybody any better or worse???

 

Thats typical, stats say 16 city and 20 highway. I get about 12-19 mpg depending on how I drive.

 

i use to average 17-20 when i had 235/70 tires on my truck but since i put 31/10.5 on it i get 15 highway at most but average around 12-13

 

We've had quite a few threads like this. I get right around what everyone else gets, 15-17mpg. Best I've gotten was 20.7mpg and that was when I moved - all highway. But my Bravada has 3.73 gears and 70 series rubber. It should get a bit better when I step up to 75 series tires (heck, may just jump to 30x9.5-15 tires).

 

15-17 here 2001 trailblazer 75 series tires, I will never buy another 4.3L chev again....

 

So you get the window sticker mileage and you fault Chevy. Right... Ok. Good luck with whatever it is you get.

Good said.

 

First off about 60% of my driving is highway (55 MPH) and the rest is 35-45 MPH and I usually get 20 MPG out of every tank full, but the last few tanks I have been warming the engine before driving and leaving it run while I walk into the daycare to drop my girls off etc....and it's gone down to about 19.1 MPG....Still very pleased for a 10 year old 4X4 4-door sport-ute with 132,000 miles on the ODO. As for the 4.3......it is hands-down one of the best engines ever built in my opinion. Only beat by other G.M. engines like that one that everyone has had the good ol' 350 or better yet it's newer version the 5.7 litre. No one has a better combination of power, fuel economy and most importantly reliability.

 

some how I doubt the window sticker said 15 mpg highway bro. just me 2 cents.
