How often should a car be started if not driven?
1 Answers
It is recommended to start the car every two weeks if it remains unused for an extended period, mainly for the following reasons: 1. Lubrication of various parts: When a car is not started for a long time, most of the lubricating oil adhering to the parts that need lubrication will flow back to the oil pan due to gravity, reducing the lubrication effect on moving parts. 2. Restarting the engine: Without the protection of an oil film, metal parts are prone to react with oxygen to form an oxide film, increasing friction and making it difficult to start the engine. 3. Battery lifespan: If the battery does not receive a charge for a long time, the sulfation process of the battery plates will accelerate, increasing the internal resistance of the battery and shortening its lifespan. 4. Battery recoverability: Due to the self-discharge effect of the battery, the terminal voltage may drop below 85%, making the battery irreparable.
