Fuel Saving Tips

DON'T Coast for the Very Best Consumption

Contrary to all the tips on here about coasting on hills or when approaching junctions/red lights to save fuel, it's not actually the most fuel-efficient way to drive. If you coast with the clutch fully depressed, the engine has nothing driving it so has to burn fuel to prevent it from stalling. However, if you come off the accelerator but leave the car in gear (the highest possible, changing down if necessary as you lose speed to prevent stalling), then the wheels continue to drive the engine through the gearbox so no fuel is needed. You lose a bit more speed than coasting due to engine compression, but if you stay in as high a gear as your speed allows then it's negligible.
