Maintenance oil: Fully synthetic oil 4L 5w40, supplied in large quantities from selected manufacturers, ensuring quality and quantity

Description :

　　Due to the fact that there are many parts inside the engine that require lubrication, and the environment of each part is different, the required lubrication performance is also different. Adding lubricating oil to vehicles requires it to be able to cope with various harsh environmental conditions within a large temperature difference range of cold and hot, thus placing higher demands on the lubrication performance of engine oil in various environments.

gasoline engine oilPre mixed with fuel

　　After mixing lubricating oil with gasoline in a certain proportion, it enters the crankcase and cylinder through the carburetor. During the intake stroke, there is a certain degree of vacuum and some gasoline evaporates from the mixture on the hot surface of the components. The lubricating oil remains in the bearings and cylinder liners to lubricate the moving parts. A small amount of used oil is discharged, and most of it burns together with gasoline. The advantage of this method is that there is no lubrication mechanism, which simplifies the engine structure. The disadvantage is that the consumption of lubricating oil is high, and there is less oil intake during idle. The lubrication is not sufficient, and the combustion of lubricating oil will also deteriorate the exhaust quality.

gasoline engine oilGood smoke suppression performance

　　The inherent structure of gasoline engines results in incomplete fuel combustion compared to four stroke combustion, and the combustion and exhaust of lubricating oil also contribute to poor exhaust quality. Its emissions cause air pollution, and economically developed countries have established emission regulations. Therefore, how to improve the emission quality of two-stroke gasoline engines is a major issue for the survival of such models in the future. Of course, the main issue is the improvement of the engine, while also requiring lubricating oil to have good smoke suppression performance.
