Replying to: gmoudy (Oct 07, 2005 11:25 pm) Same vehicle. I get 16-17 mpg around town, and 22-23 mpg on highway. Good numbers in my opinion, especially on the highway.   -gmfan

12 MPG. I smile all the way to the pump when I feed that LS2 expensive premium.   Bruce   P.S. Hemi? What's a Hemi? Replies to this message: kybilt (Jan 06, 2006 7:46 pm) dmb874 (Apr 16, 2006 5:38 pm)
#9 of 44 02 Trailblazer LS by member12 Jan 02, 2006 (1:34 pm)
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.

Replying to: gmoudy (Oct 07, 2005 11:25 pm) 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.

Replying to: bigbassguy1 (Jan 03, 2006 12:49 pm) I think 03 or 04 models have larger tanks. I also wish my 02 TB had a larger tank.

Replying to: blautens (Dec 30, 2005 1:28 pm) 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.
#13 of 44 03 TB LS 41K Miles by new57 Jan 21, 2006 (10:56 am)

#14 of 44 had 03 now have 06 by bluedad Jan 25, 2006 (5:20 pm)
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.
