Does adding 0.5 liters more engine oil affect the engine?

Excess engine oil needs to be drained out. Adding too much oil increases the engine's operating resistance, affects the vehicle's fuel consumption, increases engine noise, and raises the crankcase oil pressure. In severe cases, it can lead to oil burning. The following are the functions of engine oil: 1. Friction reduction: A sufficiently thick oil film separates the surfaces of relatively sliding parts, thereby reducing wear. 2. Sealing: Engine oil can form a seal between the piston rings and the piston, reducing gas leakage and preventing external contaminants from entering. 3. Anti-rust: Lubricating oil adheres to the surface of parts, preventing contact with water, air, acidic substances, and harmful gases. 4. Cushioning: When the pressure in the engine cylinder rises sharply, suddenly increasing the load on the piston, piston skirt, connecting rod, and crankshaft bearings, this load is transmitted and lubricated through the bearings, cushioning the impact load. 5. Cleaning: Good engine oil 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 through the flow of the lubricating oil.
