How Many Kilometers Can 1 Liter of 92 Gasoline Run?

[Richard]

Under normal circumstances, 1 liter of gasoline can support a 1.6L sedan to travel 10-15 kilometers. The specific distance depends on the vehicle condition, road conditions, and the driver's habits. Theoretically, the heat contained in 1 liter of gasoline, divided by overcoming the friction and air resistance of a 1.4-ton car, can allow the car to travel more than 50 kilometers. In reality, the efficiency of internal combustion engines is generally around 35%, with 20% consumed by the friction of the car's transmission mechanism, and 10% wasted on engine active cooling, exhaust heat dissipation, noise and vibration, and emissions. A comprehensive gasoline utilization rate of about 22% is already considered very energy-efficient. At a constant cruising speed, 1 liter of gasoline can only run about 10-15 kilometers, which is related to factors such as speed and driving habits. Generally, it is recommended to use 92-octane gasoline for engines with a compression ratio below 8.5, either 92 or 95-octane for engines with a compression ratio between 8.5-9.5, and 95-octane or higher (such as 98-octane) for engines with a compression ratio above 9.5, to ensure the optimal combustion environment in the cylinder that the engine is designed for.
