Explanation

Choosing the right gear is one of the key aspects of eco-driving. When driving in high gears with the engine at low revs, fuel consumption is lower. We should use the highest possible gear (4th or 5th) even in town, and keep the engine at low revs. In low gears, the engine runs at higher revs and uses more fuel. First gear has a lot of power but little speed, so using it for a long time makes fuel consumption shoot up. It should only be used to move off, and we should change up as soon as possible, after about 2 seconds or 6 metres.
