How often should engines be serviced?

The maintenance frequency of an engine should be determined comprehensively based on the oil type, vehicle usage environment, and manufacturer's recommendations. It is generally advised to perform basic maintenance every 5,000 to 10,000 kilometres or every 6 months, whichever comes first. Mineral oil requires replacement every 5,000 kilometres or 6 months; semi-synthetic oil can be extended to 7,500 kilometres or 9 months; fully synthetic oil allows for a cycle of 10,000 kilometres or 12 months, but for turbocharged or German-made models, It is best to reduce the interval to 7,500 kilometres. If the vehicle is frequently driven in dusty, high-temperature, or congested environments, the maintenance interval should be shortened by 20%-30%. Basic maintenance includes oil and filter replacement, along with regular inspections of the cooling system (every 10,000 kilometres), air filter (every 20,000 kilometres), and spark plugs (every 30,000 kilometres). Strict adherence to the maintenance manual, combined with adjustments based on actual driving conditions, can extend the engine's lifespan and maintain optimal performance.
