What items are replaced during a minor maintenance service?
2 Answers
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. For city driving without traffic congestion, delaying the replacement by 1,000-2,000 km is acceptable, while in harsh environments, early oil inspection is recommended. 2. Oil filter: The oil filter does not require 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 based on your vehicle's usage. Under normal conditions, replacing it before 20,000 km is sufficient. For drivers who smoke or operate in rural environments, replacement every 10,000 km is advised, while in dusty or sandy conditions, replacement every 5,000-8,000 km is recommended.
I've been driving for over five years, and I need to do a minor maintenance every six months or every 5,000 kilometers, mainly changing the engine oil and oil filter. Engine oil is like the blood of the engine, responsible for lubrication and heat dissipation. Over time, it thickens and gets mixed with metal shavings and dust. If not changed in time, it can damage the engine. The oil filter is used to filter out impurities, and it must be replaced together with the oil; otherwise, adding new oil would be a waste. Routine checks like tire pressure, brake pads, and lights are free. I also ask the mechanic to take a quick look at the cabin air filter and engine air filter. Sometimes, they just blow out the dust, but if it's too dirty, they recommend replacing it. If you drive a lot in big cities, it’s normal to replace the engine air filter every six months. If you buy the parts yourself, semi-synthetic oil plus an oil filter costs a little over 100 yuan, and another 50 yuan for labor gets the job done.
