To get even closer accuracy, follow the same procedure for several tanks of fuel then add the mileage results together and divide that by the number of tanks burned.

That's how my android ap calculates it... use Fuelog at every fillup. I'm averaging about 18.39mpg from the 4.8is (since August) with a best of 20.76mpg coming back from Cali. Doing 65mph though this thing I'm sure could hit 22mpg. Here in TX though it's hard not to utilize the 80mph speed limits.
