Fuel Saving Tips
In owning three vehicles (2 cars, 1 motorcycle), I have found that the instantaneous fuel economy is not accurate. While you can use this reading to determine driving styles that help maximize fuel economy, the absolute reading itself is probably not accurate. The computer in my 2009 Honda Fit overestimates fuel economy by 10-15%. The computer on my Subaru Forrester overestimates by about 10%. The computer on my Honda CB500 motorcycle underestimates fuel economy by a whopping 20-25%.
