    When I bought the car is 1987 with the 2.2 zeniths, I would get 22 MPG on the HWY.
    When I replaced the motor with current 2.4 but with 46 Webers I got 16 MPG on the HWY.
    Now with MFI, I get the same...about 16 MPG.

    When checking your mileage make sure your odometer is working properly. I never realized that mine, while working, was under registering by about 15% or over 2 mpg.

    A good drive in the country can see it down to low teens.


    The fewest I ever saw was sometihng like 22 litres per 100km (not sure of the mpg there) crusing at 225km/h on deserted French motorways for two and a half hours at a strectch.......

    Big fun and no tickets...
    A US gallon is about 16.7% less than the imperial gallon.

    My ST does around 18 MPG with normal driving. I was overtaking a friend in convoy thrill seeking through the French twisties en-route to Classic Le mans last summer...... My friend behind said..... there goes another 10 Euro's.
