Which efficient driving guideline helps avoid unnecessary fuel consumption?

Question

DentroTest · Accepted Answer

Among the efficient and safe driving techniques promoted by the DGT, starting the engine without pressing the accelerator is essential to avoid wasting fuel. Modern electronic injection systems precisely and automatically meter the mixture needed for starting, so accelerating is completely unnecessary and sends consumption and emissions soaring. By contrast, doing without engine braking is a serious mistake, since when rolling while holding the vehicle back with a gear engaged, fuel consumption is absolute zero. Likewise, warming the engine at idle with the vehicle stationary is a pointless waste of fuel; the right approach is to set off smoothly after starting (respecting only the seconds needed for the pneumatic circuit to build up working pressure, if applicable).
