How should you drive to achieve fuel-efficient driving and reduce fuel consumption?

Question

DentroTest · Accepted Answer

To practice fuel-efficient driving, the fundamental rule is to drive in the highest gear possible that still allows for vehicle control, while keeping the engine at low RPMs. In modern engines, this usually means keeping the engine speed between 1,500 and 2,500 revolutions per minute (RPM) for petrol vehicles, and between 1,300 and 2,000 RPM for diesel. By using high gears, the engine rotates fewer times to cover the same distance, injecting fuel less frequently and reducing internal friction. Options suggesting high RPMs are incorrect, as high engine speeds skyrocket fuel consumption and unnecessary mechanical wear.
