    Is possible...

    Drummer,
    Don't panic about the 'good mileage', these cars are really suseptible to octane ratings of the fuel.
    On 93 mine pulls down 31-33 open road, on 91 it only gets 28-29. I only put 90 in it once because I was afraid I would have to push it if I didn't and the mileage dropped even more! I tried hard not to use the boost with the lower grade fuel, I only travelled about 80 miles and found a 'BP' with 93 and filled the remaining 3/4 tank with that. No idea what the mileage was, but the fuel gage dropped awfully fast for that short amount of driving!

    Gerardo,
    You might want to check this article out regarding T-Bird ABS systems. It is the best article I've seen on the system.

    I was only getting around 15mpg at best on highway. Now I get around 23-24mpg on the highway. About 340rwhp, I have no complaints.

    The previous owner of my SC figured it got about 20 MPG... But they weren't highway miles.

    I have a window sticker to a 1990 SC that says 24 Mpg Highway.

    In my modded '93 I get about 20mpg, which is a city/highway mix.

    So I just did my first full refill of the tank since I bought my (stock) 90' last week and I got 18.3 mpg. That's ALL city, driving to school and back, running errands, etc. Not sure if that's good or not for all city.

    I seem to get between 19 and 23 MPG depending on how much highway driving I do. Im hoping it can get at least 25 if I did nothing but highway driving. But even if it doesn't, its not the reason I bought this car. Seriously, the handling is great on our twisty country roads in Georgia; like it was designed specifically for the roads where I live.

    For all city and stock...it's not bad!!! Now you need to save a few pennies drop in a K&N intake filter and a Cat-Back exhaust system to free it up a little and power and gas mileage should go up!!! plus keep putting the 93 octane in it!!! You will be much happier with the way it runs!!!

    My first 89 XR7 got 28 mpg regularly and was a 5 speed car. My current 90 with tired engine can't be getting anything close to that....
