Coasting in neutral or with the clutch pressed can save fuel by reducing engine drag while rolling downhill. However, if you are going uphill, it’s better to keep the car in gear as this enables the engine to help you climb up and make use of the available power. This also applies when changing gears – shifting too soon can cause unnecessary strain on your engine, resulting in a higher fuel consumption. For best results, changing gears at the right rpm is recommended. This ensures that your engine is running as efficiently as possible and can help you save fuel.
