How Long Should You Start a Car That Hasn't Been Driven for a Long Time?

[Hector]

When starting a car that hasn't been driven for a long time, the duration can range from as short as 2 to 3 seconds to being unable to start smoothly. Below is relevant information about car starting: 1. Reasons for the malfunction indicator light: ignition system failure, starting system failure, fuel injection system failure, intake system failure, ECU failure, fuel quality issues, engine oil lubrication system failure. Main symptoms of engine failure: poor acceleration or stalling, poor engine idling or stalling, inability to start ignition. 2. Correct driving methods: Warm up the engine before starting. In northern regions, preheat for at least 5 minutes in winter. In southern regions, 3 minutes. After warming up, drive at low speed for 1-2 kilometers until the water temperature reaches above 80 degrees before driving at high speed. Avoid driving at high gears with low engine RPM, as this can severely damage the engine. That is, while driving, the engine RPM should not be below 1200 or above 3000. (Low-speed driving with the clutch partially engaged, such as when entering or exiting parking spaces, is a different matter.) When shifting from 1st to 2nd gear, the car should accelerate until the engine RPM reaches 2000-2500 RPM. For other gears, accelerate until the engine RPM reaches 2000 RPM.

As a veteran driver with 20 years of experience, I've seen too many vehicles left parked for long periods. Before starting the engine, don't rush to ignite—take 10 seconds to let the vehicle complete its self-check. Pay attention to the sound when starting: it's best if it succeeds on the first try, and continuous cranking shouldn't exceed 5 seconds. After ignition, let the engine idle for at least 15 minutes to allow the oil to fully lubricate every corner of the engine. For cars parked for more than three months, it's advisable to first check the battery voltage; if it's below 12 volts, charge it. Remember to drive slowly for two kilometers after starting to remove rust from the brake discs and allow the tires to regain their roundness. Once, my neighbor's car, which had been parked for half a year, made clunking noises from the transmission when driven directly—all because it wasn't warmed up enough.

As an auto repair shop technician, I deal with stalled cars every day. Before starting, always check three things: if the battery voltage is below 11.9V, charge it first; pull out the dipstick to check for oil stratification; and inflate the tires to at least 2.5bar. Turn the key and wait 3 seconds to start. If successful, let it idle for 10 minutes. The key is to ensure the turbocharger is fully lubricated, otherwise the bearings can easily fail. During this time, check the dashboard warning lights and sniff the exhaust for any burning oil smell. Then drive at low speed, not exceeding 40 km/h, for at least 5 kilometers to allow the transmission gears to break in. Last week, a BMW that had been parked for half a year was started and driven off immediately by the owner, resulting in piston ring scuffing and an 8,000 yuan repair bill.

Last year, I parked my car for three months during a business trip, and the battery was completely dead when I returned. Now I've learned my lesson: if the car won't be used for more than two weeks, I disconnect the negative terminal. The most nerve-wracking moment is during startup—if I hear a clicking sound, it means the battery is low. After a normal startup, it's essential to let the engine idle for at least 10 minutes; otherwise, it can damage the engine. Once, I started the car and drove off in a hurry, and the transmission jerked badly. It's best to drive for over half an hour to let the fuel pump flush out any sediment buildup. Don’t forget to run the AC to eliminate musty odors and press the brake pedal a few times to remove rust. Now, using a charging station makes things much easier—no worries no matter how long it's parked.

My MPV often sits parked for two to three weeks. Before starting it, I squat down to check for oil stains underneath. The moment I dread most during startup is seeing the battery light illuminate on the dashboard, so I now keep a jump starter ready. After ignition, I avoid turning on the AC immediately, waiting instead for the coolant temperature gauge to reach 90 degrees. I let the engine run for at least 12 minutes, longer in winter. This time is perfect for cleaning the windows and checking the wipers. For the first couple of drives, I brake gently to wear off any rust that may have formed on the discs and pads. My neighbor drove his car after three months of parking and ended up burning the alternator belt, costing over 700 yuan in repairs.
