mileage
 

Just wondering what kind of mileage everyone is getting with their blazer? I'm trying to figure out if mine is average or not. I'm getting about 15 around town. I haven't really taken any trips yet that would let me figure out the highway miles. Is 15 about average?

I'm getting 15.5-16mpg depending on the weather with my 12 mile (one-way) commute that is about 80% 55mph and includes 1 stop sign and 5 stop lights. My personal best was after my tune up with O2 sensors starting to get lazy and that was 18mpg. I hope to see atleast 18mpg this summer if/when I drive it.

Mine avererages 18.1 mpg. I haven't reset the overhead console for at least 3 months now.

15 with a bad O2 sencer and a big hole in the exhaust.

Unless you have tuning to take advantage of the higher octane, high octane will do nothing. You are most likely seeing an increase because with regular, you were having detonation causing the pcm to retard the timing. The higher octane will fight detonation. I bet if you were to give your engine a good seafoam treatment that you would get the same mileage with regular. Most detonation is caused by carbon buildup in the combustion chamber.

I get 16.5 to 17 when driving like a grandmother.

130000 miles and no mods.

I am getting 12mpg since about 2 months ago but I need to change an 02 sensor and the fpr AND I have a heavy foot...15mpg is not THAT bad...our trucks are gas hogs!

I'm getting 16.5 and my driving is mainly around town. Some pretty good stretches of 45 to 50 MPH driving, but more than my fair share of stoplights.

Today I get to go 30 miles of highway driving, hoping to pretty good on mileage.

Wow, I'm getting like 1000 mpg! (haven't gone anywhere in a few days.)
