It is acceptable to service a car once a year if it's not driven frequently. Below are the potential hazards of infrequent car usage: Severe Drain: Long periods of inactivity can lead to issues such as rusted brake discs, stiff transmission systems, and severe battery drain. Fluid Degradation: Engine oil that remains inactive for extended periods can degrade, forming deposits that lead to carbon buildup in the engine, significantly reducing lubrication efficiency. Additionally, acidic substances can cause corrosion to engine components. Oil Film Deterioration: When a vehicle is parked for long durations, the lubricating oil film on the engine cylinders and piston surfaces can deteriorate due to exposure to oxygen and other corrosive acidic or alkaline elements in the air. This can form gummy deposits, causing the oil to lose its lubricating properties.

When I was younger, I made a similar mistake by thinking that since my car wasn't driven often, regular wasn't necessary. The next year, I noticed increased engine noise and difficulty starting. The mechanic explained that even unused engine oil oxidizes and deteriorates, while seals and rubber hoses age and crack more easily when left idle. Not to mention the natural discharge of the battery. Now, no matter how busy I am, I make sure to perform basic checks every six months—checking oil levels, tire pressure, and battery voltage over a weekend. I replace any necessary consumables promptly, as repair costs far exceed maintenance expenses. Safe driving is far more important than saving a little time.

As a veteran long-distance driver with 15 years of experience, I've seen too many vehicles break down due to untimely . Even if you only drive a few thousand kilometers a year, the engine oil can absorb moisture and deteriorate, brake fluid with excessive water content may cause braking failure, and tires under prolonged single-point pressure are prone to deformation and bulging. I recommend performing basic maintenance at least twice a year: inspect the air conditioning and cooling systems in spring, and change the engine oil and antifreeze before winter. Keep a battery charger in the garage and start the car for ten minutes each month to recharge. These details can significantly extend your beloved car's lifespan.

Last week, I just dealt with my friend's car. He only drives it three or four times a year and only does annual , but the engine malfunction indicator light was fully lit. Upon disassembling the engine, we found the engine oil had emulsified and deteriorated, and the fuel injectors were completely clogged. The mechanic said rubber and plastic parts start to harden and crack after two years without maintenance, and the battery is prone to failure due to power loss. It's recommended to start the car for half an hour every quarter to recharge the battery, and replace aging parts like wiper blades every six months. For long-term parking, it's best to use a jack to relieve tire pressure and cover the car with a protective sheet to prevent dust.

Don't be fooled by low mileage! My neighbor's in the underground garage only drove 2,000 km in two years with just annual maintenance, yet ended up needing a transmission overhaul. The dealership pointed out that the coolant's anti-corrosion additives degrade and corrode the radiator, hydraulic fluid separates causing steering failure, not to mention deformed tires requiring all four replacements. Now I start mine monthly to recharge the battery and have the shop check suspension bushings and brake fluid moisture content every six months. Remember: cars are machines - idleness causes more damage than usage. Penny-pinching often leads to pound-foolish repairs.
