1 Answers
Buick Regal's oil can be changed when the oil life is below 50%, and the specific value can be determined based on the car's actual usage condition. Here is some relevant information about automotive engine oil: 1. The role of engine oil: Automotive engine oil serves to lubricate, clean, cool, seal, reduce friction, prevent rust, and protect against corrosion in the engine. 2. Engine oil determines the engine's lifespan: The engine is the heart of a car, containing many metal surfaces that move and rub against each other. These components operate at high speeds, in harsh environments, and can reach working temperatures of 400°C to 600°C. Under such severe conditions, only qualified lubricating oil can reduce wear on engine parts and extend their service life.
