    only getting 9 mpg help

    Really easy on the pedal like rangel said and got 14.06 last check. Haven't changed anything just easy on the pedal and that's around town driving to work. Just easy on the pedal. I can live with 13-14 mpg city. 9 was a little extreme for a stock/small tire Tahoe thanks
