How much fuel does a 460 horsepower engine consume at idle for one hour?

This fuel consumption has not been calculated, and it is not recommended for drivers to idle in place. There are no legal regulations regarding this in China, but in many foreign countries, idling for more than 3 minutes to warm up the engine can result in fines, and it also causes significant environmental pollution. Idling in place likely consumes a very small amount of fuel, but it is highly detrimental to both the environment and the vehicle, leading to excessive carbon buildup, which can affect the vehicle's normal operation in the future. Additional information: Modern vehicles display instantaneous fuel consumption on the dashboard to inform the driver of the current fuel usage during movement, but most vehicles do not show instantaneous fuel consumption when idling.
The fuel consumption of a 460-horsepower engine at idle for one hour really depends on the specific vehicle and conditions. From my experience in car repair, a high-power gasoline V8 engine typically uses about 2 to 4 liters of fuel at idle, depending on factors like idle RPM, temperature, and whether the air conditioning is on. A 460-horsepower engine is commonly found in pickup trucks or SUVs. If the idle is set at 700-800 RPM with the air conditioning on, fuel consumption might be slightly higher, around 3 liters per hour. However, older engines or cold environments can increase fuel consumption. For accurate data, it's best to use an OBD scanner to measure real-time consumption, rather than guessing, which wastes both time and fuel money. To save on fuel costs, it's advisable to avoid prolonged idling during daily use.
