How Long Can a Car Be Parked Before It Needs to Be Started?

[McFrank]

It is recommended to start the car if it has been parked for half a month. Below is some relevant information about starting the car: Function of the Starting System: The starting system converts the electrical energy from the battery into mechanical energy through the starter motor to initiate the engine's operation. The purpose of the starting system is to transition the stationary engine into an operational state. This requires an external force to rotate the engine's crankshaft, enabling the pistons to begin moving up and down, allowing the intake of a combustible air-fuel mixture into the cylinders, and subsequently entering the subsequent working cycles. Effects of Long-Term Non-Use on the Car: When a car remains unused for an extended period, most of the lubricating oil that should coat the moving parts will flow back into the oil pan due to gravity. This reduces lubrication at various moving components. Without the protective oil film, metal parts are prone to react with oxygen, forming an oxide layer, which increases friction and makes starting the engine difficult.
