Hi. Recently finished repairing a '90 Firebird for daily driving. Restoring a 1969 Chevy CST/10 (I guess this would be your nightmare... 350ci V8, 3 speed auto, 5000lbs, shaped like a brick).

I got the car for free from my aunt in CA. Shipped it here, and started working on it. A water pump, 6 new fuel injectors, and some odds and ends for inspection later, and it's on the road. But, went through the 1st tank of gas, and it got a paltry estimated 11-12 mpg average. Thats factoring on a 13 gallon tank... Barely got to 150 miles before filling up with a gallon or two to spare.

Now, I admit to having some fun with it, just getting it on the road. And right now at the moment the A/C is down, so driving with the windows down is all I have in the hot TX days (T-tops and a lot of glass on this car don't keep it cool). But, even as I try to drive MPG minded, I can still watch it suck gas like mad.

EPA rates it as 16 city, 25 hwy, and most my driving is highway driving.

So, wondering if there are any other 3rd gen owners here.

Stats about the car:
3.1L V6, 140 hp and 180 ft lb of torque. Fuel injected
4 speed auto, the 700R4
270,000 miles, and the car runs very strong for it's age.
Factory Trans-Am body kit, was an option in '90. Does also reduce the drag Co. over the stock Firebird
Roughly 3200 lbs, I believe.
.32Cd via Thirdgen.org
Originally a California car, so emissions and such have been well kept.
