How many liters of engine oil does the Envision 28t require?

[DiStephen]

The Envision 28t model uses 4.5 liters of engine oil. This vehicle is equipped with a 2.0T engine, which requires fully synthetic Dexos-1 engine oil with a viscosity grade of 5W-30. Functions of engine oil: 1. Lubrication and friction reduction - Between the piston and cylinder, as well as between the crankshaft and bearings, there is rapid relative sliding. To prevent excessive wear of components, a sufficiently thick oil film is needed to separate the sliding surfaces, thereby achieving the purpose of reducing wear. 2. Cooling - Engine oil can carry heat back to the oil pan 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 pan. Through the flow of lubricating oil, it cleans contaminants generated on the working surfaces of components. 4. Sealing and leakage prevention - Engine oil can form a sealing ring between the piston rings and piston, reducing gas leakage and preventing external contaminants from entering.
