Some guy in GB said he got 90MPG highway, I didn't believe him.
I'd been driving it like crazy, always topping out gears and accelerating as fast as possible. When I checked at the pump I got a horribly disappointing 50MPG :-p
So I decided to drive conservatively just to see the MPG I'd get. I was not driving super conservative, I was just driving like a car, accelerating calmly, turning the engine off at long lights, and racing every so often.
I checked again at the pump . . . 200 miles . . . 2 gallons of gas . . . :D
Yay four stroke engines~!
