Fuel Saving Tips
Despite common belief speed is not really connected to MPG. The Revolutions Per Minute (RPM) of your car's engine is what really matters. If your car has a Tachometer watch your RPM's, keeping them low will use less fuel. Depending on the gearing of your transmission is what determines how fast you travel at a certain RPM.
