I'm curious the gas mileage you all are getting in the trailblazer SS. Please specify AWD or 2WD. In some articles I have been reading people have been saying 14 city/ 17 highway with some saying 18 city/ 22 highway.

 

Right now Im getting about 13 in the city (partially my fault) and about 24 on the higway. 2WD TBSS

 

12.5 regular driving. Well, whatever regular is for an LS2 powered 2WD SUV.

Let's just say that I'm taking the bulk of my mileage in fun.

 

I just drove a 500 mile round trip that averaged 85mph the entire trip. I got 17.4 mpg. Not bad at that speed avg and a little "spirited" driving along the way. I bet it would have been easily 20+ at 55-65 mph.

 

My AWD 13 city 15 hwy. and sometimes 11.5-11.8 when I need to give it the spurs .

 

Well since the wife has it and takes it back and forth to work she gets about 14.5 but we took it on a trip to Colorado and averaged 17-18MPG on the way up and 18-19MPG on the way back to the coast. We were running about 70-75 up and 75-80 back. An LS2 and 4.10 gears ROCK in the mountains I might add, we were cruising the whole time w/ the cruise set and she didn't downshift once. Oh yeah its a 2WD LT...

 

right now driving in hurry i get 14 in the city have yet to take a long trip to check on the highway. 2wd

 

My AWD Averages like 15.5 city and 19-20 highway

 

That's cuz you have one of those nifty little 'Vektor' tunes in it, huh?
