How Long Should a Car Be Parked Before Starting It?

[LeilaniMarie]

If a car has been parked for a week, it should be started; if parked for about half a month, the car should be started and driven for three to five kilometers. The steps to start an automatic transmission car are: 1. Turn the ignition key to the power position; 2. Press the foot brake and shift the gear from P to N; 3. Release the foot brake and start the engine; 4. Warm up the car while stationary; 5. Press the foot brake, shift the gear from N to D, and release the handbrake; 6. Slowly release the foot brake and gently press the accelerator to start smoothly. The steps to start a manual transmission car are: 1. Fully depress the clutch pedal; 2. Push the gear lever to engage first gear; 3. Gently press the turn signal lever downward to activate the left turn signal, alerting vehicles in front and behind; 4. Press the horn button to alert pedestrians in front of the vehicle that you are about to start; 5. Release the vehicle's handbrake; 6. Lift the left foot until the clutch is in a semi-engaged state, causing the vehicle to vibrate slightly; 7. The vehicle begins to move; release the clutch and gently press the accelerator.

I heard experienced drivers say that the biggest fear when a car sits idle for too long is battery drain. Especially in winter, the battery can lose about 1% of its charge daily, and after two weeks, it might not start. Last week, I was on a business trip for ten days, and when I returned, I had trouble starting the car—the dashboard lights were dim, so I had to get a jump start. Now, I start the car every seven days and let the engine run for fifteen minutes to recharge the battery. Additionally, the engine oil settles at the bottom of the oil pan, leaving the lubrication passages empty. Idling helps circulate the oil again, preventing dry friction damage to the engine. Tires under prolonged pressure at a single point are prone to deformation, so moving the car a few meters can reduce the risk of deformation. If the car remains unused for over three weeks, it's best to take it for a short drive to let the rust on the brake discs wear off.

My neighbor's car sat unused for a month, resulting in a dead battery that cost 500 yuan to replace. Since then, I've developed the habit of starting my car if it hasn't been moved for over ten days. Long-term parking isn't just about battery issues - gasoline in the tank gradually evaporates and deteriorates, with ethanol-blended fuel being particularly prone to separation and forming gum deposits that can clog fuel lines. Running the engine for over ten minutes helps circulate fresh gasoline. Additionally, internal engine components lack oil lubrication and are susceptible to rust, especially precision parts like camshafts. However, I don't start it too frequently either - there's no need to worry about short periods of 3-5 days. If I'm going on vacation for more than two weeks, I inflate the tires to the maximum recommended pressure to prevent deformation and disconnect the battery's negative terminal for extra peace of mind.

As a car owner with ten years of experience, I recommend starting the engine if the car is parked for more than two weeks. A friend from the car factory told me that if the vehicle remains stationary for over 15 days, the battery will suffer deep discharge, damaging its lifespan. Last week, I tried leaving my car parked for three weeks without moving it, and after jump-starting, I clearly felt the engine struggling to turn over. Now I've developed a habit of starting the car every 10 days. During idling, I turn on the air conditioning system to prevent refrigerant line blockages. I also check the dashboard warning lights because prolonged parking can cause electronic components to become damp and short-circuit. Additionally, I press the brake pedal a few times to avoid the brake calipers seizing up. If possible, driving a few hundred meters is even better, as it helps keep the steering system and suspension bushings active.

I have a car specifically for long-distance trips, and I'm most afraid of long-term parking when it's idle. The mechanic reminded me that if the car isn't started for more than twenty days, the transmission fluid will settle, leading to insufficient lubrication of the valve body. I make sure to start it every two weeks for half an hour, and I also check the exhaust pipe for any water vapor deposits. In summer, special attention must be paid to small animals in the engine compartment, as they can chew through the wires. Last time, after parking for a month, the engine belt was gnawed by a rat, leaving a gap. Now, whenever I start the car, I open the hood to inspect the belt's condition and feel the pipes for any signs of aging or cracks. I also press down on the body to test the shock absorber's rebound, because springs can easily deform if compressed for too long.

During the pandemic last year, my car sat idle for two months without moving. When I started it, there was severe abnormal engine noise. The repair shop said oil drainage caused hydraulic tappet cavitation damage. Now I pay special attention to starting the vehicle regularly, especially for hybrid vehicles which require extra caution. Long-term dormancy of hybrid systems can lead to power battery under-voltage protection, and replacing a deeply discharged battery costs over ten thousand yuan. I start the car every ten days for twenty minutes to maintain battery activity. I also operate the power windows a few times to prevent window track jamming. When parking in rainy weather, I check the sunroof drainage holes – a colleague previously had water leakage due to clogged sunroof drains. Regular operation helps maintain all components in proper working condition.
