How Often Should You Start a Car That's Not Being Driven?

[Roger]

It is recommended to start a car that remains idle for long periods at least once every two weeks, primarily for the following reasons: Lubrication of various car components: When a car is not started for an extended period, most of the lubricating oil that should coat the moving parts will flow back to the oil pan due to gravity, reducing lubrication effectiveness in these areas. Regarding engine startup: Without the protective oil film, metal parts are more prone to react with oxygen, forming an oxide layer that increases friction and makes starting the engine more difficult. Concerning battery lifespan: If the battery does not receive regular charging over a long period, the sulfation process of the battery plates will accelerate, increasing internal resistance and shortening the battery's service life.
