Does a car need an oil change if it hasn't been driven for half a year?

The oil change cycle is half a year or 5,000 kilometers driven. As long as the oil change cycle requirement is met, even if the car hasn't been driven for half a year, the oil still needs to be changed. The main functions of engine oil are to clean, cool, and lubricate the engine, ensuring reduced wear on internal components during operation. It also serves to seal against leaks and prevent rust and corrosion. Under normal circumstances, oil consumption is minimal. The primary reason for changing oil is that esters and polyolefins in the oil undergo oxidation, and wear particles from engine components enter the oil, shortening its lifespan and causing internal components to deteriorate. Engine oils on the market are divided into three types: mineral oil, semi-synthetic oil, and fully synthetic oil. Conventional mineral oil should be changed every six months or 5,000 kilometers; semi-synthetic oil has a replacement cycle of about eight months or 7,500 kilometers; while fully synthetic oil should be changed annually or every 10,000 kilometers.
As a car enthusiast, I believe it's best to change the oil after leaving a car parked for six months. Over time, the oil can deteriorate, absorb moisture, and produce acidic substances that corrode internal engine components. I once had a car that sat unused for half a year, and when I started it, the engine noise increased noticeably, and the oil had turned cloudy with significantly reduced lubrication effectiveness. Regular oil changes can protect the engine and extend its lifespan. During long-term parking, it's advisable to choose a dry location and use synthetic oil for better durability, but even then, don’t exceed one year. Other points to note include the battery possibly losing charge—so charge it beforehand—and increasing tire pressure to prevent deformation. Ultimately, spending a bit on an oil change for your beloved car is worth it to avoid costly major repairs. Regularly checking the dipstick for oil color and clarity, along with timely maintenance, provides peace of mind.
From a vehicle usage experience perspective, the engine oil should be changed for a car parked for six months. During this period, the oil oxidizes, absorbs moisture, loses lubricating properties, and may damage piston rings or cylinder walls. Once, after prolonged parking, I noticed increased fuel consumption and found deteriorated oil corroding components during inspection. It's advisable to prioritize an oil change to prevent potential issues. Also, check if the brake fluid and coolant need replacement, and inspect for any aging in the electrical circuits. Choose a garage for parking to avoid oil degradation from rain and sunlight. If you drive infrequently, aim to change the oil every six months, regardless of mileage. Regular maintenance means fewer hassles and a safer, smoother driving experience.
A car parked for half a year needs an oil change for a simple reason - prolonged time causes oil deterioration which can damage the engine. It's recommended to change it to ensure safe driving. Also check if the tires are deformed and whether the battery has sufficient charge. Cover the car with a dustproof cover during parking to reduce damage. Proper maintenance saves money and hassle.
