help: gas mileage
I have 2004 Cayenne S and the computer always says 10mpg wherever I am, highway or city.
I also have to fill in the gas after 160miles (city driving) or 180-200 miles (city+highway). When I say refill means when the thing beeps and its around 20 gallons. Is it meant to take this much gas?
