Will overheating of gasoline engine cylinders cause a decrease in engine efficiency?

Overheating the engine can affect efficiency, leading to an increase in oil and fuel consumption, for the following reasons:
1. The engine overheats and the cylinder operates rough, leading to an increase in the trend of detonation, resulting in an increase in heat loss
2. Overheating leads to a decrease in lubricating oil performance and an increase in friction loss.
3. The engine overheats, the intake air decreases, and the combustion deteriorates.
