How much engine oil should be added to the Envision 28t?

[DiLuna]

The Envision 28t requires 4.5L of engine oil. Functions of engine oil: 1. Lubrication and friction reduction - There is rapid relative sliding between the piston and cylinder, as well as between the main shaft and bearing shells. To prevent excessive wear on parts, a sufficiently thick oil film is needed to separate the surfaces of the sliding parts, thereby achieving the goal of reducing wear. 2. Cooling - Engine oil can carry heat back to the oil tank and then dissipate it into the air, assisting the radiator in cooling the engine. 3. Cleaning - High-quality engine oil can circulate carbon deposits, sludge, and worn metal particles from engine components back to the oil tank. Through the flow of the lubricating oil, it washes away dirt generated on the working surfaces of the parts. 4. Sealing and leakage prevention - Engine oil can form a sealing ring between the piston rings and the piston, reducing gas leakage and preventing the entry of external contaminants.
