Engine technology continues to advance, constructed gradually precision, oil products are getting low viscosity. 

   

As science and technology advances, more and more sophisticated car engine structure, the gap is getting smaller and smaller engines, engine friction surface treatment is also very smooth, sophisticated engine no longer need to rely on large-viscosity oil to improve sealing of the engine, the low viscosity oil seal has been fully meet the needs of sophisticated engines. 

 

Currently, due to the low viscosity multigrade oil also has to save energy for a wide range of advantages, they have been widely used worldwide. Major car manufacturers in the world has agreed to promote the use of low-viscosity oil as the initial installation of oil and oil service vehicles. By the Japan Automobile Manufacturers Association and General Motors, Ford and Daimler Chrysler car jointly developed GF-4 specification gasoline engine oil, and only 10W / 30,5W / 30,0W / 30,5W / 20,0W / 20 this five viscosity grade, that these cars in Japan and Europe are also in the country to use low viscosity engine oil, low viscosity oil can fully meet the needs of a variety of vehicles. 

 

The use of low viscosity, long-span multi-grade oil has as many advantages, but we must note that the inadequacies of low-viscosity oil is oil film strength and volatility. Due to the low viscosity of the oil is often used in low molecular weight hydrocarbon base oil, abrasion resistance film is difficult to be assured, and low molecular weight components of the base oil boiling point lower, likely to be volatile, easily lead to insufficient oil pressure and red. And just modified organic molybdenum additive oil can improve anti-wear properties, and can reduce friction and reduce the oil temperature, thereby reducing the volatilization of oil and to prevent oil oxidation, compensate for the lack of low viscosity, the multi-grade oil.
