Without the use of an accurate fuel consumption gauge of some description, this is only an educated guess, but my current driving style does yield a lot more mileage than other techniques I have tried.
I'd like to build a mpguino or something similar in the near future.
Do you use anything other than odometer to monitor fuel consumption?
