Fuel Saving Tips
A tip for Manual Transmissions - Coasting with the engine idling uses very little fuel (just enough to keep the engine going), but modern engines shut off completely the fuel supply when letting the engine slow the car (foot off the accelerator/gas pedal). So use engine braking as much as possible, and watch your fuel efficiency soar. Remember though that engine braking doesn't show your brake/stoplights so cars behind might be unaware of your slowing. Also remember to avoid labouring the engine by letting the RPM drop too low. Idling is necessary when the engine reaches 1000RPM or less.
