What kind of engine oil should be used for Haval F5 maintenance?

The manufacturer recommends using fully synthetic engine oil with a specification of 5W-30. Brief description of engine oil: Engine oil, also known as engine lubricant (English name: Engine oil), has a density of approximately 0.91×10 (kg/m³). It serves multiple functions for the engine, including lubrication and wear reduction, auxiliary cooling, sealing and leakage prevention, rust and corrosion protection, as well as shock absorption. Often referred to as the "blood" of a car, engine oil consists of two main components: base oil and additives. The base oil is the primary constituent of lubricating oil, determining its fundamental properties, while additives compensate for and enhance the performance shortcomings of the base oil, imparting new characteristics, making them a crucial part of lubricating oil. Main functions of engine oil: Lubrication between pistons and cylinders, as well as between the main shaft and bearing shells, involves rapid relative sliding. To prevent excessive wear on components, an oil film must be established between the two sliding surfaces. A sufficiently thick oil film separates the surfaces of relatively sliding parts, thereby reducing wear. Auxiliary cooling: Due to its relatively low specific heat value and location inside the engine, engine oil itself does not have a cooling effect. However, during engine operation, the heat generated by fuel combustion can be carried back to the oil tank by the engine oil and then dissipated into the air, assisting the radiator in cooling the engine. The actual cooling is performed by the water (or antifreeze liquid) outside the engine casing.
