Here's why:
* Improved Air Density: Colder air is denser. While this might seem beneficial, denser air means less oxygen per unit volume. High-performance engines rely on a precise air-fuel mixture for optimal combustion. Warmer air is less dense, containing more oxygen per unit volume, leading to better combustion and more power.
* Oil Viscosity: Cold oil is thicker, increasing friction within the engine. This reduces efficiency and can lead to increased wear. Warmer oil flows more easily, reducing friction and improving lubrication.
* Fuel Volatility: Cold temperatures can affect fuel vaporization, leading to poor combustion and potentially a rougher idle.
* Engine Efficiency: Many engine management systems are calibrated for optimal performance at specific temperatures. Deviations from this optimal temperature range can lead to less efficient operation.
While a warm engine is generally better, excessively high temperatures can also cause problems. The ideal operating temperature is usually within a specific range, allowing for optimal power output and preventing damage.
