370Z highway mileage?

Also, the computer, as many have pointed out, is only an estimate. The only true way to determine mileage is the old-fashioned way. Fill the tank to full, drive a known amount of miles, fill the tank to full again and then divide the number of miles driven by the gallons just filled.

Don't forget, c410006, there are no points for second palce.
