How Often Should You Start a Car That's Not Driven for Long Periods?

If a car is not driven for an extended period, it is recommended to start it approximately once every two weeks. Prolonged parking can make the vehicle difficult to start. Even when a car is turned off for long durations, the battery continues to discharge. Over time, the battery may become completely drained, and its lifespan will also shorten. Starting the car and running its components can help recharge the battery, although the amount of charge is minimal. However, this may lead to significant carbon buildup. Therefore, it is advisable to drive the car around rather than idling it in place. Maintenance tips for long-term parking: Clean the exterior and interior of the vehicle beforehand, as dirt left on the paint for too long can damage it. Ensure the battery remains sufficiently charged by performing regular inspections and maintenance to prevent battery depletion.

When a vehicle is left idle, the biggest concerns are battery failure and fluid deterioration. The battery naturally loses 1% of its charge daily, and if unused for over a month, it typically won't start. My habit is to start the car every 10 days. Idling in place can lead to carbon buildup, so I shift to D gear, lightly press the accelerator to maintain 2000 RPM for 5 minutes, which also helps circulate the transmission fluid. Remember to turn on the air conditioner's internal circulation mode to blow out moisture from the ducts. It's best to keep the fuel tank at about 1/4 full, as too much gasoline can oxidize and form gums. Keep a tire pressure gauge handy, and if the pressure drops below 2.0 bar, inflate the tires promptly.

I own two cars and often alternate between them, so I'm very particular about handling the idle vehicle. First, disconnecting the negative terminal of the battery is the safest, but this will reset the car's computer data. A compromise is to start the car for 20 minutes every Wednesday after work, and take a couple of laps around the parking lot to remove rust from the brake discs. Remember to set the air conditioning to external circulation and blow air on the windshield to prevent the evaporator from molding. Once when I was on a business trip, I booked a valet warm-up service via my phone, where the technician came every seven days to start the car for half an hour and also checked the tire pressure. During the cold winter months, I add two drops of special anti-rust oil into the engine oil filler.
