Fuel Saving Tips

Coast in gear on some cars

Modern fuel injected cars have a fuel cut off function if the car is coasting in gear and the engine revolutions are kept around 2000rpm or higher (this may vary, of course). If you have a trip computer with instantanious consumption function, this can be easily verified by coasting in gear at highway speeds - if the instantanious consumption goes down to zero consumption (or infinite mileage), your car has this function. This means the car uses zero fuel during in gear coasting as opposed to out of gear coasting where fuel must be supplied to the engine to keep it idling.
