What are the advantages and characteristics of automobile engine grease

(1) High compressive strength of oil film: the compressive strength of generated lubricating oil film reaches 225MPa, while the average compressive strength of mineral oil film is about 22.5MPa. The high compressive strength of oil film enables the driving force transmission system software to immediately lubricate components, such as rolling bearings, oil rings, valve systems, transmission gears, etc., with faster anti-wear effect.

(2) Viscosity characteristics: During the application period, mineral oil will expand its viscosity because of the same effect of heat dissolution and air oxidation decomposition, which is caused by unstable chemicals in mineral base oil. The generated base oil does not have such unstable chemical substances and has very good fusion performance with food antioxidants. Therefore, when applying the same food antioxidants, it has a stronger anti-oxidation effect than mineral oil to reduce the vibration of grease. As a result, the generated lubricating oil exhibits good viscosity and special greasiness properties, with viscosity improvement of less than 50% in vehicle engine tests in MS flow 30 E. Viscosity change in lubricating oil application is also affected by the decrease of shear performance of viscosity index improver. The shear stability of automobile engine oil and the performance of maintaining the viscosity level depend on the variety and quality of the viscosity index value improvement agent used in the oil secret recipe. The generated base oil has excellent viscosity characteristics, in other words, only a small amount of viscosity index value modifier is needed to generate oil, so the shear reliability of oil can achieve the maximum value of oil vibration reduction. Mineral base oil has a wide range of compounds and relative molecular weight. Under continuous high temperature, chemicals with low relative molecular weight are easy to volatilize, leading to volatilization damage, while chemicals with higher relative molecular weight remain and increase viscosity, leading to difficult starting of automobile engines. The formation of base oil can well control evaporation performance, can reduce volatile damage.

(3) ultra-low temperature fluidity and high temperature volatiles: compared with mineral base oil, the formation of base oil is more easy to flow at lower temperature, low pour point, limit pump partial dry lubricant temperature is also low, at ultra-low temperature than mineral oil can quickly lubricate and reduce damage, but also reduce operating load and internal stress.

(4) Natural material rationality: the friction resistance of oil generation is less than mineral oil, which can reduce the driving force damage, and can save natural material under the corresponding efficiency and load. In addition, the generated oils can be mixed with low viscosity oils (5W or 10W/30) without compromising volatile and viscosity control regulations. Compared with the conventional 15W/40 oil, the fuel can be saved by more than 3%.

The rest of the parts: the generated base oil has the ability to resist decomposition reaction, and is not easy to convert into sludge and accumulation. Some generated oils also have natural solubility and clarity, which can improve the quietness of components.
