    How to get best economy out of a diesel

    A comment was made in Carsguide recently regarding trailing throttle when driving a diesel. Could you explain this in little more detail, as I am sure all diesel owners would love to get the best economy from their vehicle?

    A diesel is most efficient when operating at a steady throttle. It's no more efficient than a petrol engine when it's accelerating and decelerating. The best way to get the most out of your diesel is to maximize the time spent at a steady throttle, as it would be if you were driving on the highway. You also need to work within the optimum torque range for your engine. Accelerate quickly to the top end of the torque band and change up when you reach it, don't over-rev the engine, and change down when the engine's speed drops to the bottom end of the band.
