Is it okay to start the car for only 15 minutes if it's not driven frequently?

[DiEvelyn]

It is not advisable to start the car for only 15 minutes if it's not driven frequently. Generally, the engine should run for at least half an hour to ensure proper lubrication of the vehicle's components and allow the car battery to charge sufficiently. This practice is beneficial for the vehicle's daily use. The battery is an essential part of a car and can be categorized into traditional lead-acid batteries and maintenance-free batteries. Battery maintenance methods include: 1. Avoid overusing the battery; 2. Regularly clean the positive and negative terminals of the battery; 3. Periodically check the vent holes on non-maintenance-free battery caps to prevent blockage; 4. Avoid low battery water levels; 5. When the car is parked for an extended period, start the vehicle once a week to charge the battery.
