[FC] easy one, gas tank capacity for '64 brier

[corvanatics@corvair.org]

Hi there...I filled mine up to a point where it won't take any more (18.1) 
gals...wrote my mileage down, drove on the thruway to Albany at about 65 most of 
the way...recorded mileage when I filled the tank up again...subtracted the 
two mileages...divided the result by the gals used....presto...gas mileage is 
obtained....but you have to be aware of your driving habits....going 
fast....hard accelerations from lights, etc...will diminish the gas mileage. I hope this 
helps...
