How often should a car be started if it is not driven frequently?

It is recommended to start the car at least once a week or every two weeks. Long-term inactivity of a vehicle can cause significant harm, including battery depletion, tire blowouts, and oil sedimentation. For vehicles parked for extended periods, it is advisable to start and drive them once a week if possible. This helps recharge the battery, evenly distribute tire pressure, and most importantly, ensures that the engine oil adheres properly to the internal components of the engine, which is crucial for vehicle maintenance. If a vehicle remains idle for a long time, the oxidation of engine oil becomes more severe. Oxidized oil first affects the lubrication efficiency of the engine and transmission, and secondly, acidic substances can corrode mechanical components. The longer the vehicle remains unused, the more severe the oil oxidation becomes, leading to increased dry friction between the cylinders and pistons upon restarting, accelerating component wear and making the engine harder to start. When a vehicle is parked, the oil in the seals and pipelines remains stagnant, causing uneven pressure distribution around the seals. The side under greater pressure experiences more deformation. The longer the vehicle remains idle, the harder it becomes for the seals to recover, eventually leading to permanent loss of elasticity. Electronic components and connectors in vehicles require protection against water, moisture, and corrosion to prevent malfunctions. For parked vehicles, the risk of moisture affecting electronic components or wiring connections increases significantly, and the likelihood of failure rises with prolonged inactivity.

Having driven for decades, my experience tells me that if a car isn't used often, it's best to start the engine once a week and let it run for about 15 minutes. This helps charge the battery and prevents starting difficulties due to power loss—I once had to call a tow truck after returning from a business trip because the battery was dead, costing me a lot of unnecessary money. You should also drive it around for a few minutes to keep the tires moving and prevent deformation, and to rotate the brake pads to avoid rust. Letting the engine oil circulate internally lubricates the components and prevents carbon buildup, or else cylinder walls can develop issues over time. Don't forget to turn on the AC system to blow air and prevent mildew odors. Keep the fuel tank full or use a stabilizer to preserve the fuel. Remember to stick to this routine and be extra diligent in winter and summer to prevent damage from freezing temperatures or high heat causing tire blowouts. Keeping the car moving regularly saves money, hassle, and ensures safety.

I'm a housewife and don't use the car much except for picking up the kids. My husband taught me to start the engine every two weeks and let it run. The battery discharges slowly, so 10 minutes of idling is enough to recharge it. Otherwise, if we suddenly need to use the car and it won't start, the repairs can be very expensive. We bought a simple charger to hook up for extra insurance. Tires can flatten if left too long, so I drive around the neighborhood to check the tire pressure isn't too low. It also keeps the engine lubricated to prevent rust and ensures the brakes stay responsive for safety. Last long holiday, the car sat for two months, and when I started it, there was a loud abnormal noise—cost me hundreds in repairs. So now I set a weekly reminder on my phone to do this every Sunday. It's become a simple habit, and it gives the family peace of mind.

With years of car research, I understand the drawbacks of an inactive engine. It's recommended to start the engine for 15 minutes weekly: idling allows the oil pump to lubricate cylinder walls, preventing carbon buildup; the battery discharges and recharges promptly, avoiding deep depletion. Ideally, drive the vehicle short distances to engage brakes and tires, preventing deformation, and reduce suspension strain. If parked over a month, disconnect the battery negative terminal or use a smart charger for maintenance, monitoring voltage to prevent faults. Neglecting this sharply reduces battery life, risks burning out the starter motor, and accelerates wear from degraded fluids. Simple maintenance ensures longevity, aided by tools like pressure gauges.
