Fuel consumption is at its highest during situations that put extra strain on the engine. Key moments include:
- Cold starts when the engine is cold and less efficient.
- Rapid or abrupt acceleration, which demands a large burst of fuel.
- High-speed driving, as increased aerodynamic drag forces the engine to work harder.
- Stop-start urban driving with frequent acceleration and idling.
- Towing heavy loads or carrying excessive weight.
- Climbing steep hills that require more power.
- Using air conditioning, especially at lower speeds.
These factors cause the engine to burn more fuel than usual due to increased workload, resistance, or inefficiency. Driving behavior, vehicle condition, and environmental conditions also influence fuel consumption peaks. Smooth driving, maintaining vehicles properly, and avoiding high speeds can help reduce fuel consumption.
