If you anticipate hazards Regular servicing can establish a basis for good fuel economy and speed changes well in advance, you will need to brake less and before you start driving. A well-serviced engine gives you the thus accelerate less.

Emissions and fuel consumption will drop to zero due to the overrun fuel cut-Avoid short trips off. The engine and emission control system need to reach their proper working temperature in order to minimise fuel consumption and Change gear early to save fuel emissions. An effective way of saving fuel is to change up quickly through the A cold engine uses disproportionately more fuel. The engine only gears.
