Gas Mileage Calculator?

[63Futura]

Does anyone know if there are any mileage calculators out there where you can plug in variables such as engine displacement, RPM, speed and gearing information and get a rough estimation of your MPG? All of the ones that I have seen deal more with your $$ per year in gas costs, and all use mileage and gas put in as variables.
Thank you.

You need to know the brake specific fuel consumption. From memory 0.48 is good, 0.60 is crook. Enjoy!
