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

The maintenance cycle of a car depends on its condition. Some people who don't drive their cars often consider servicing only once a year, but it's best not to do so. It's recommended to service every six months. There are several hazards of not driving a car frequently: 1. Cars are not afraid of being driven, but of being parked: Long-term parking can easily lead to problems such as rusted brake discs, stiff transmission systems, and deeply discharged batteries. 2. Engine carbon buildup: Engine oil that remains inactive for a long time can deteriorate and form deposits, leading to engine carbon buildup, significantly reducing lubrication effectiveness. Some acidic substances can also cause certain corrosion to engine components. 3. Deterioration of lubricating oil film: If a vehicle is parked for an extended period without use, the lubricating oil film on the engine cylinders and piston surfaces can deteriorate due to exposure to oxygen and other corrosive acidic and alkaline components in the air, forming a gummy substance and losing its lubricating effect. 4. Friction accelerates component wear: The longer a vehicle is parked, the more severe the deterioration becomes. When the engine is started again, dry or semi-dry friction can occur between the cylinders and pistons, accelerating component wear. Moreover, the starting resistance increases significantly, making it difficult to start, and prolonged periods can completely damage the engine.
I've been driving for over ten years and have often encountered situations where the car sits idle in the garage. Even if you only drive a few thousand kilometers a year, it's still advisable to maintain it on schedule. The engine oil oxidizes and deteriorates inside the engine, and over time, its lubricating effectiveness diminishes. Additionally, fluids like brake fluid and coolant absorb moisture from the air, which can affect their performance. Long-term parking can also cause localized aging and deformation of tires, and the battery is prone to losing charge. While some car owners think frequent maintenance isn't necessary due to low mileage, sludge in the engine accumulates gradually. I recommend checking the fluid conditions at least every eight months and having a mechanic inspect the rubber components on the chassis for cracks. This can help avoid costly repairs down the road.
