Car lubrication service is a maintenance item that involves the regular replacement of engine oil and oil filters. Its purpose is to provide effective lubrication for engine components, reduce friction loss, and remove internal carbon deposits through fresh engine oil. High-quality engine oils such as the Petronas Syntium series, which adopt the CoolTech formula, can strengthen the oil film, absorb heat, and enhance high-temperature stability. The 0W-30 model of this series is priced at approximately RM259, balancing cleaning performance and anti-wear properties. The service should be performed according to the recommended interval in the vehicle manual, usually every 5,000 to 10,000 kilometres or 6 months. Using fully synthetic oil can extend the replacement interval to 15,000 kilometres. Long-term maintenance can reduce fuel consumption and extend the engine's service life.
