Geely Binyue's 1.5T engine requires approximately 5.5 liters of engine oil, but since there are no oil packages available in this exact specification, a full 6 liters must be used at a time. Precautions for adding engine oil to the Binyue: When adding engine oil, ensure that the oil level is between the min and max marks on the dipstick. The oil level should neither be below the min mark nor exceed the max mark. If it is below the min mark, it may lead to insufficient lubrication, which can accelerate engine wear. If it exceeds the max mark, it can increase the engine's operational resistance, resulting in reduced power and higher fuel consumption. Functions of engine oil: Lubrication to reduce wear: Between the engine's pistons and cylinders, as well as between the main shaft and bearings, there is rapid relative sliding, which can cause wear. High-quality engine oil forms a sufficiently thick oil film between these sliding surfaces, separating the moving parts and thereby reducing wear. Cooling: Engine oil carries heat back to the oil pan and dissipates it into the air, assisting the radiator in cooling the engine. Cleaning: Good engine oil can circulate carbon deposits, sludge, and worn metal particles from engine components back to the oil pan, flushing away contaminants generated on the working surfaces of the parts through the flow of the lubricant.
