How many kilometers can one liter of 92 gasoline run?

Under normal circumstances, one liter of 92 gasoline can support a 1.6L sedan to run 10-15 kilometers. If driving on general urban roads, the fuel consumption is about 8L/100km, and one liter of gasoline can run approximately 12.5 kilometers. Additionally, it is also related to the vehicle condition, road conditions, and the driver's driving habits. Theoretically, the heat contained in one liter of gasoline, divided by the friction and air resistance of a 1.4-ton car, can run 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, emission noise, etc. A comprehensive gasoline utilization rate of about 22% is already quite energy-efficient. Therefore, at a constant cruising speed, one liter of gasoline can only run about 10-15 kilometers, which is related to comprehensive factors such as speed and driving habits. It is generally recommended to use 92 gasoline for engines with a compression ratio below 8.5, either 92 or 95 gasoline for engines with a compression ratio between 8.5-9.5, and 95 gasoline or higher-grade 98 gasoline for engines with a compression ratio above 9.5, to ensure the in-cylinder gasoline combustion environment suitable for the engine.
I did a specific comparison on this before - there's really no standard answer for how far one liter of 92-octane gasoline can take you. My 1.5L sedan does about 8-9 km in city driving, but immediately jumps to 12-13 km on highways. My neighbor's SUV gets literally halved, only managing 5-6 km in traffic jams. Actually, engine displacement makes the biggest difference - a 2.0T car with aggressive throttle input can consume 40% more fuel than a 1.6L. Last time I saw the repair shop owner test, the same car driven by a novice versus an experienced driver showed a 3-liter fuel consumption difference! Low tire pressure is even worse - driving 100 km with underinflated tires burns an extra half liter. Don't even calculate the AC usage - when the compressor kicks in, the fuel consumption gauge jumps at least 0.5 liters per 100 km.
