What Items Are Replaced During a Minor Maintenance Service?

[LeHenry]

Items that need to be replaced during a minor maintenance service: 1. Engine oil: The replacement intervals for engine oil are categorized into three types based on time and mileage: mineral oil (6 months or 5,000 km), semi-synthetic oil (9 months or 7,500 km), and full-synthetic oil (1 year or 10,000 km). These intervals can be adjusted based on driving conditions—delaying replacement by 1,000-2,000 km is acceptable for urban driving without traffic congestion, while harsh environments may require earlier oil inspection. 2. Oil filter: The oil filter does not need separate inspection; it should be replaced whenever the engine oil is changed. 3. Air filter and cabin air filter: The air filter can be replaced according to vehicle usage conditions. Under normal circumstances, replacement before 20,000 km is sufficient. For drivers who smoke or operate in rural environments, replacement every 10,000 km is recommended, while sandy or dusty environments may require replacement every 5,000-8,000 km.
