With what type of gears and engine speed is fuel consumption reduced?

Question

DentroTest · Accepted Answer

Efficient driving is based on driving for as long as possible in high gears with the engine at low revolutions (RPM). This is because high gears allow the vehicle to cover more distance for every engine revolution, optimizing fuel burn. As a general rule, it is recommended to shift to a higher gear between 2,000 and 2,500 rpm for gasoline engines and between 1,500 and 2,000 rpm for diesel engines. Driving in low gears or with the engine highly revved unnecessarily increases consumption and engine wear.
