Fuel Saving Tips
Some say you should shift into neutral when coming to a stop while using an automatic transmission, but this is actually counterproductive. In fact, because of the fact that the vehicle can run off of its own rotational momentum in gear while coasting (thereby completely shutting off fuel temporarily), shifting into neutral will actually reduce your gas mileage because more fuel must be used to keep the engine running. Also, it puts unnecessary wear and tear on the mechanical components in addition to being illegal in at least a dozen states.
