What is the gas millage of a Toyota Celica?

To Calculate the "Gas Mileage" of your car you can use your trip meter. Zero it at the next fill up then when you fill up again make note of the mileage. Now take the miles and divide it by the gals pumped. Example: 225.4 / 11.125 = 20.260674157303370786516853932584 or 20.26 MPG Don't believe what any Carmaker say about the EPA estimated miles are they are never correct. Hope This Helps.
