How Long Should You Warm Up Your Car?

[MacBella]

Warm-up time should never exceed 3 minutes. Here is more information about warming up your car: 1. Hazards: Excessive warm-up time not only increases fuel consumption and emissions, but also causes certain degrees of carbon buildup and damage to the engine. You can start driving once the engine reaches a stable and normal idle speed. 2. Principle and method of warm-up: Since the engine oil flows back to the oil pan due to gravity, driving immediately after starting the car will increase the dry friction load between various moving parts of the engine, leading to damage. Warming up the car heats the oil, reduces its viscosity, and increases its fluidity, thereby providing better lubrication for the engine.
