Is it okay to service a car once a year if it's not driven often?

It is acceptable to service a car once a year if it's not driven frequently, but it is recommended to service it every six months. In fact, not driving a car regularly can have more negative effects on it, just like a knife will rust if not used. The hazards of not driving a car often include: 1. Brake disc rusting, transmission system becoming stiff, and deep battery discharge; 2. Engine oil that remains unused for a long time can deteriorate, forming deposits that lead to engine carbon buildup, significantly reducing lubrication effectiveness, and some acidic substances can also cause corrosion to engine components; 3. The lubricating oil film on the engine cylinder and piston surfaces can deteriorate due to exposure to oxygen and other corrosive acidic and alkaline components in the air, forming gummy substances and losing their lubricating properties.
I have some experience to share regarding maintenance frequency for cars that are driven infrequently. Take my family's SUV for example—it only clocks 2,000-3,000 kilometers a year and spends most of its time parked in the garage. I believe an annual service is generally sufficient, but it depends on specific conditions. For instance, engine oil degrades over time, especially full synthetic oil which has a shelf life of about one year. Extended parking may lead to sludge buildup. The battery discharges quickly when idle, making it prone to depletion or damage. Tires can deform or become unbalanced under prolonged static pressure. To mitigate these issues, I start the engine weekly and let it run for ten minutes to maintain lubrication, and check tire pressure every six months to ensure it stays around 2.5 bar. Brake fluid and coolant may also absorb moisture and deteriorate, so replacing them during maintenance is crucial. While an annual service saves money, neglecting minor issues could lead to costly repairs later. Regular upkeep is key—safety always comes first.
As a car owner, I don't drive much, just short commutes and weekend trips. An annual maintenance schedule seems suitable for infrequent drivers, but attention to detail is crucial. For instance, my car parked outdoors suffers accelerated component degradation due to exposure. Engine oil may deteriorate after 12 months, compromising lubrication. Batteries left uncharged can drain completely, causing startup failure next time. Underinflated tires may develop flat spots. During maintenance, I recommend changing oil and filters while checking battery voltage. For vehicles parked over six months, inflate tires to recommended PSI or use smart chargers to maintain battery. Follow the manual's maintenance frequency - manufacturers typically suggest every 5,000-10,000 km or annually, but prioritize time intervals for low-mileage usage. Regular simple checks can prevent unexpected expenses.
