Should You Warm Up the Car in P Gear or N Gear?

[Alexandra]

Whether to warm up the car in P gear or N gear depends on the situation: 1. If the intended direction is reverse, use P gear for warming up, as no gear shifting is required from warming up to driving; 2. If the intended direction is forward, you can use either N gear or P gear, as both gears disconnect the powertrain and transmission, having no impact on the car. The reasons for warming up the car are: 1. After prolonged parking, the engine oil flows back to the oil pan at the bottom of the engine, leaving the upper part of the engine without oil and lubrication when starting after a long period of inactivity; 2. Before the engine reaches its operating temperature, the fuel system cannot effectively vaporize gasoline completely due to the low temperature.
