If I am stopping and going quit a bit, it will drop down in the LOW 12's but on the highways (60mph) its always shows between 15---20mpg

*** OF COURSE I DONT RELY 100% ON THE FUEL ECONOMY METER, I always write my mileage on my fuel reciept when I fill it up at the pump, and then when I refuel, I will subtract my mileage and divide it into the gallons I purchased ****
