Fuel Saving Tips
If you have a diesel car, keep the revs down where possible. Shifting up at 1,500-2,000 rpm while pushing the gas pedal hard will use less fuel than treating the gas pedal gently but allowing the revs to climb for any given rate of acceleration. If you can find your engine's torque curve, see where the torque peak is and under normal circumstances keep the engine below that speed.
