When to Change Engine Oil?
1 Answers
The replacement interval for engine oil varies depending on the type of oil used: 1. Mineral oil needs to be changed within 5,000 kilometers, and should not exceed 5,000 kilometers at most; 2. Semi-synthetic oil can extend the oil change interval appropriately to 7,500 kilometers; 3. Fully synthetic oil can be extended to 10,000 kilometers for each change. The interval can be appropriately adjusted based on different driving conditions, driving habits, and other factors. Functions of engine oil: 1. Lubrication: Maintains the viscosity between the cylinder and piston, ensuring normal operation, reducing friction between components, and minimizing wear; 2. Cooling: Assists the car's cooling system to some extent in lowering the temperature inside the engine; 3. Cleaning: Removes sludge, carbon deposits, and other impurities attached to engine parts; 4. Sealing: Seals gases within the engine piston and piston rings, reducing the entry of external impurities.
