What does the appearance of Oillife mean in Honda?

[DelKathryn]

Oillife indicates the remaining life of the engine oil. The following is a related introduction about the functions of engine oil: 1. Lubrication and friction reduction: It forms an oil film on the surfaces of two sliding components to prevent friction during operation, ensuring smooth functioning. 2. Auxiliary cooling: The engine generates high temperatures during operation. When the oil reaches the operating parts, it absorbs heat and then carries it away, aiding in heat dissipation. 3. Cleaning: It can carry carbon deposits, sludge, and worn metal particles from engine parts back to the oil tank through circulation, washing away dirt generated on the working surfaces of the parts. 4. Sealing and leakage prevention: The oil can form a seal between the piston rings and the piston, reducing gas leakage and preventing the entry of external contaminants. 5. Rust and corrosion prevention: The lubricating oil adheres to the surfaces of parts, preventing contact with water, air, acidic substances, and harmful gases.
