How often should I change the oil if I don't drive much?

Change the oil within 12 months even if the vehicle isn't driven much. The oil change procedure is as follows: 1. Run the engine until it reaches operating temperature; 2. Engage the parking brake and lift the vehicle; 3. Unscrew the oil filter and drain the old oil; 4. Apply new oil to the gasket of the new filter; 5. Pour new oil into the oil pan; 6. Check for leaks under the engine; 7. Lower the vehicle, check the dipstick, and start the engine; 8. Turn off the engine and recheck the oil level. The functions of engine oil are: assisting in engine lubrication and friction reduction, cooling, sealing and leak prevention, rust and corrosion protection, and shock absorption.
I have a car parked in the garage that I rarely drive, only covering about two to three thousand kilometers a year. However, I still insist on changing the oil every six months, regardless of whether I drive it or not. This is because engine oil absorbs moisture from the air, oxidizes, and deteriorates over time, leading to reduced viscosity and poor lubrication performance, which can cause internal engine rust or wear. The last time I delayed the oil change for a whole year, the engine made a creaking noise upon startup, and upon inspection, the oil had emulsified. Referring to the vehicle manual, most cars recommend an oil change every 6-12 months; even with low mileage, one shouldn't slack off. Regular maintenance can avoid major repairs, extend the car's lifespan, and save long-term costs. Now, I set a phone reminder to get it done every six months—simple and worry-free.
Engine oil deteriorates even when the car isn't driven; it's not just about mileage. Prolonged exposure to temperature fluctuations in the engine causes oil to acidify and form sludge that clogs oil passages. When I drive infrequently, I follow the manufacturer's standard - inspect every 6 months and replace when necessary. Conventional oil requires annual replacement at minimum, otherwise lubricants evaporate and piston rings may seize. My experience: parking in shaded areas slows deterioration, but don't exceed one year. While you're at it, check the air filter and battery to prevent minor issues from becoming major repairs. The entire process isn't complicated - a quick 30-minute visit to the repair shop handles it all.
