Fuel Saving Tips
engine braking
the ecm most on newer cars (fuel injected 95+) stops putting fuel into the engine when you let go of the throttle and the car needs no help to go forward, so down shifting before stops and letting the car coast down in a lower gear can keep the engine from idling and using fuel, plus you will be ready to go at a better gear if the light turns green before you have to stop.
