How to choose motorcycle oil

How to choose motorcycle oil How to choose a motorcycle oil? Motor oils commonly used in motorcycles are mainly two types: one is engine oil, and the other is gear oil. Most graded convertible bin four-stroke motorcycles use only engine oils, such as "Suzuki 125", "Tianhong 90" and "Jialing 70". Most pedal-type motorcycles also need to add gear oil to the transmission. Such as "Guangyang", "Magnolia" and so on. In particular, it is important to note that the engine oil is different from the gear oil in composition and function, and must not be interchanged. 

Engine oil has four functions: lubrication, sealing, heat dissipation and cleaning. Correct selection of engine oil is the key to vehicle maintenance. A good engine oil can improve the performance of the body, save energy, reduce consumption, and extend life. The motorcycle engine has two-stroke engine and four-stroke engine. The two structures and working conditions are different. They have different requirements for oil. They should be used differently and not interchangeable or mixed. Some small-package motorcycle oils are marked with 2F and 4T, which means two-stroke oil or four-stroke oil. 

The four-stroke motorcycle engine is basically the same as the engine structure of the car, and both of them can be used universally. However, the working conditions of motorcycle engines are poor, so the oil level should be higher. Although the grade of oil is classified according to the standards of the American Petroleum Institute (API), it is represented by English letters: S is the gasoline engine oil, A, B, C, D... are the oil grades, and the higher the grade is, the higher the grade is. Motorcycles use at least SE grades and high-end cars recommend SG grades. Another parameter of oil selection is the viscosity of the oil. In the Central Plains region, 30 oils are generally used in summer, and 40 oils are generally used in winter. The current development trend is the use of composite motor oils, such as "Guangyang 125" motor, and SG15W/40 engine oil, which can be used in all seasons. 

The two-stroke engine oil, when used together with gasoline, is combusted and then discharged together with the exhaust gas from the exhaust pipe, thus requiring less carbon residue and good high-temperature cleanability, and cannot be replaced with other oils.

As for the quality classification of two-stroke oil, it is currently not completely unified internationally. In fact, FASO, FB, and FC are generally used by Japan Automotive Standards Organization (JASO); China is divided into ERA, ERB, ERC, and ERD. FC grade oil is generally recommended. FC is a semi-synthetic engine oil, which has the characteristics of less smoke and good detergency. It is an environmentally friendly, low smoke edge. 

Understand the above knowledge, you can refer to your motorcycle instructions to buy their own oil, but please note the following:

1. Go to a larger specialty lubricant shop. It has been observed that a considerable amount of motor oil sold by the motorcycle maintenance department and motor vehicles on the market is a counterfeit product. 

2. Please buy products from famous manufacturers. Such as Great Wall of China Petrochemical Great Wall Lubricating Oil Company, Feitian of Lanzhou Refinery, etc., Hengyun Motor Oil produced by Henan Hengyun Group has undergone rigorous evaluation tests of national authorities and has been certified by Japan TASO, which is a kind of high quality and reliable. Motorcycle motor oil. 

3. Do not use products like "Protection of God" at will. The high-quality engine oil itself contains various additives for improving the performance. The higher-priced “Protective God” is not only redundant, but may also have negative effects.
