I agree the speedo is off ay freeway speeds by about 2 MPH faster than you are actually going. I passed 2 radar signs and it's always the same. Driving 70 MPH the sign reads 68 MPH. I think the MPG is close too. I have calculated the mileage several times after filling up and it's very close. But I don't get anywhere near 36 MPG even going down hill. The advertised MPG must be for a car averaging 45 MPH and wind aided with a 20 MPH wind at it's back.
