MPG 04 TB EXT by michaelcozens

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.

12 MPG. I smile all the way to the pump when I feed that LS2 expensive premium.

02 Trailblazer LS by member12

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.
