Why are oils becoming more and more low-viscosity?

Once, many auto repair factories no matter what kind of vehicle maintenance oil, are to change 40 viscosity oil, simple and rough, which precisely reflects the manufacturing process of most engines in the year.

Nowadays, lower and lower oil viscosity has become the development trend of engine manufacturing and lubricant industry, Japan, South Korea and the United States, including the German system that has been using high viscosity oil, are also promoting the use of low viscosity label (0W20, 0W30, 5W20) oil. So why are oils becoming more low-viscosity?

Engine processing technology is becoming more and more sophisticated

With the progress of technology, the processing technology of the engine is getting higher and higher, the gap between the parts is getting smaller and smaller, and the engine with such high precision parts has low requirements for the oil viscosity used. Low viscosity oil flow rate is fast, can quickly reach the parts of the friction surface to fully lubricate the engine.

Environmental protection, fuel saving environment

High viscosity oil will cause poor lubrication, increased fuel consumption, loud noise problems, the use of low viscosity oil will also reduce the engine running resistance, but also reduce fuel consumption, reduce emissions, in line with the international advocacy of energy saving and environmental protection of automobile production technology.

The problem of low oil film strength was solved by the whole synthesis process

When the engine is running, there will be a layer of oil film between the parts to protect the two friction surfaces from contact. When the oil resistance at high temperature is insufficient, the oil film will break, and the engine parts will lose protection and direct friction will cause wear.

Many people question the oil film strength of low viscosity oil, and the reason why low viscosity oil is widely promoted now is inseparable from the combination of fully synthetic oil.

The protection of synthetic oil can be achieved with a very low oil viscosity and sufficient oil film strength and high temperature shear resistance, so that the engine can use a lower oil viscosity to ensure lubrication and reduce fuel consumption, killing two birds with one stone.

Ribang SP/C5, GF-6 and other standard oils are 20 viscosity grades, which can reduce engine wear, stimulate engine power, improve fuel economy, and bring extraordinary performance to your car!

Not only excellent lubrication, but also has good cleaning performance and stability. It can minimize the wear and tear of the sludge and carbon-deposited parts, and also maintain the appropriate viscosity level of the oil at the high temperature and high speed of the engine to ensure effective sealing and reduce oil consumption.
