Chevrolet TrailBlazer Real World MPG

Comments

  • I have been suprised, on the highway if I drive with a light foot I can get over 20mpg. I have the I6. Any headwind takes it down to an average of 18 or so. In town it is just so-so 14. I put in a KN air filter and it seems to boost MPG just a little on the hiway. If nothing else the KN filter is good for the engine. :)

    Around town I get on the average of 18 mpg. On a trip to California I usually get 22 mpg. Love the mileage I get with this SUV and the comfort it provides on a trip.

    I have a 04 TB EXT as well, but have the V8. On a trip to Disney, I averaged 18 - 19 MPG. Around the city I average 15 MPG. It is close to being on par with the I6. I went with the extra horsepower and have not regretted it.

    Same vehicle. I get 16-17 mpg around town, and 22-23 mpg on highway. Good numbers in my opinion, especially on the highway.

    I have an '03 TB. Around town 16.5-17. Just drove from Nashville to South Bend, IN. and averaged 24.7 round trip.
  • 12 MPG. I smile all the way to the pump when I feed that LS2 expensive premium.

    P.S.
    Hemi? What's a Hemi?
  • I have the 4.2L 4x4 with the 3.23 back end. It has over 62,000 miles on it. I get on average about 18mpg, but I drive a good mix of highway and city traffic. Between Baton Rouge and Houston, I got 23mpg averaging about 65mph.

    A few months ago, my gas mileage dropped to 14, but I noticed it needed a new air filter. I replaced it and mileage went back up again. I use shell 87 octane gas.

    Not bad gas mileage. I had to pull a 5,000 lb dual axle featherlite, and the 4.2 pulls it pretty good. I could use a little more power off the line, but it still works very well. No problems to report yet. I am already sold on the 2008 redesiged Trailblazer unless they go unitbody.
  • my 02 TB LS is lucky to get 300 miles per tank (apx 16.5 MPG) I have 82K on it and replaced air filter last summer.

    Friends of mine have 8 cylinder silverados that get same if not better mpg.

    overall I think its not too good and I think gas tank should be at least 22 gal vs 18.

    I think 03 or 04 models have larger tanks. I also wish my 02 TB had a larger tank.

    2006 TrailBlazer SS ! I smile all the way to the pump, and cry on the way out! Seriously, I checked the mileage on an 8 hour round trip from home. Mostly interstate, driving very conservatively, averaged 17.2 mpg. BTW, I don't always fill up with premium, never noticed any difference either way.

    i get average of 16 mpg.

    pure hwy somtimes gets 20-21mpg
  • With the 03 TB LS I tracked every tank I put in it ( 56k at trade) I was always 17.4 - 18.5 mixed driving and 20.2 hwy. Just got 06 LT w/ v8, still breaking it in ( 650 miles so far) but the V8 w DOD is a blast to drive. Showing 17.4 first tank, mixed driving. ;)
  • I have a 03 TB EXT LT V8// I think it is ok most of the time but the dash and everything there gets very hot! I don't know what is wrong but right now the light for the air bag stays on? I also get the seat belt light on as well.
    I just out of warranty and don't know what I should do? :confuse:

    Does anyone have any experience with these and do any of them work and actually increase the MPG?
    Thanks

    Gets about 13.5 MPG in town and 21 MPG hiway at 70-75 mph. These are calculated, not from the DIC which runs about 1.0-1.5 MPG higher. Stay away from "gas savers" that involve magnets and things that create turbulence. Have never seen any documented, independent lab or dyno tests for these.
  • hey
    i have a 2004 trailblazer LT when ever im driving and i turn the wheel and i sometimes hear this grinding or louder rubbing noise in front end so i went to the dealership under warranty and they sayed it was the mud flaps and the dealer installed them before i bought it and still the tire isnt even close to the mud flaps...they come up with some good ones somtimes! :mad:

    can anyone relate to this?

    thanks :)
