Ive gone 35 miles or so.
As far as gas mileage ..I get EXTREMELY good gas mileage on mine for some reason
My fuel light usually doesnt even come on until around 180 miles. My best mpg so far is 67mpg...my worst is 48. The day I got 48 ..the only real difference was it was really windy out.
I wont hijack this thread about mpg lol
