You can't complain about gas mileage with that engine. Do Corvette owners complain about gas mileage? No, why, because they bought the big power plant for a reason... if you wanted better gas mileage, you should have gone with the smaller engine.

I had one and my insurance is now actually lower with a Vette. The former had 4 wheel drive is likely why. I have a SUV company car now, otherwise would have kept it. The Vette is now the fun weekend car. I also get over 30 MPG on the dash readout on the interstate on the Vette, not that gas is an issue. Have fun and enjoy it.

OK, the Trailblazer SS is a fast and large vehicle; through the years any vehicle that carried the SS badge was fast and did poorly in gas.

When the vehicle was purchased as new, the window sticker will tell you, the average gas mileage expected was 14 city and 19 hwy, (on a good day, down hill in neutral), so this is not a vehicle for those looking to get good gas mileage or save the planet. If gas consumption is key for you, try a smaller vehicle or engine.

That being said, this truck is fantastic, it looks great and it cannot be confused with anything else on the road. It has a powerful Bose stereo system, but you will keep it off most of the time because the symphony coming out of the engine compartment and exhaust system is intoxicating, it makes you want to keep the engine revving all the time, which could lead to a few speeding tickets.

You could order a early Nova SS optioned with a 6 cylinder. I have owned Impala SS and a Camaro SS small block V8. You buy with performance not thrift in mind. Actually the standard Trailblazer 6 gets poor mileage as well.

"Actually the standard Trailblazer 6 gets poor mileage as well."

I've had two in a row, and they both average 24 mpg on the highway with the straight 6. I think that is pretty good for a full frame SUV.

2007 black/grey Trailblazer SS 6.0 LS2.

I love my truck, but the quality isn't what I expected. I'm glad that I have the 12 month/12k mile warranty, because the cheap plastic interior parts. I knew what I was getting into regarding the gas mileage and full synthetic oil changes LOL. Since I bought it in 4/2010, I had to replace the oil pan gasket, rear air compressor, muffler, power steering pump, all of the driver side speakers, radio, interior trim for broken tabs that hold the parts in place, heater core, and the weather stripping on all four doors. I will probably have to replace the from struts soon under warranty. Other than all the small headache stuff, it's a cool truck.

I have a 2007 TBSS 6.0 AWD, and it's so funny, love the way the truck looks, but like many other owners, the craftsmanship is poor, excluding the engine.

I have replaced:

1. Rear-end months into ownership, Dealer changed the ratio, not as quick.

2. Heater coil.

3. Rear glass hatch separated from the glass, how did that happen, who knows. (I'm a female, weight 140, rarely open the glass hatch, go figure)

4. The front hubs roaring unbearable, need to replace again.

5. On the list to be replaced are the moldings around the doors, windows and damn sunroof.

6. Rear doors never close tight, need to slam the door.

7. Fog lights had to be replaced. One would work, never both at the same time.

8. The gas sensor went out right after filling up the tank.

I think that's about it, but I love my TBSS, going to drive it till the wheels fall off.

Gas isn't a issue yet at $3.70 for premium in MI, I don't like being the last person off the line... catch me if you can :)
