I've been doing it the old fashioned way; fill up the tank, set the built in H3 tripometer to zero. Went about 303 miles. Then after filling the tank I divided the 303 miles by the amount of gallons used. 303 divided by 19.64 yields about 15.4 miles per gallon. This was mixed city/highway driving though. Have about 600 miles on the H3 so far. Thanks for the link; makes things easier.
