Classification of motor oil
Motor oil is divided into mineral oil, semi-synthetic oil and fully synthetic oil because of its different base oil.
In the past few years, mineral oil has been widely used in China due to its economic price and strong versatility. However, in recent years, due to the application of high technology and the improvement of cylinder manufacturing technology, there are basically only some low-end and mid-range cars. Only mineral oil is still used, and full synthetic oil has been listed as standard.
Fully synthetic oils have a higher viscosity index than ordinary mineral oils. With the same oil film index, synthetic oils can be achieved with lower viscosity, while mineral oils need to be thicker than full synthetic oils to achieve. Moreover, the viscosity change of the synthetic oil with temperature changes is very small. Therefore, under high temperature and severe cold conditions, the diesel engine oil supplier can maintain an appropriate viscosity and provide appropriate protection for the engine. In the same working environment, the life of fully synthetic oil is much longer than that of mineral oil.
Do not mix engine oil
Generally, the owner's manual has an oil quality requirement, and because of the different design styles of different car systems, the requirements for oil are different. It is recommended that the owner go to the original factory to replace the oil supplied by the manufacturer. If you replace a non-original oil after a mechanical failure, the manufacturer may not pay compensation.
Engine oils produced by different manufacturers cannot be mixed, because various manufacturers add additives such as anti-wear agents and antioxidants when they are developed. Mixing these additives produced by different manufacturers may cause chemical reactions. The indicators of diesel engine oil make engine oil ineffective. . And the oil produced by the same manufacturer but with different grades cannot be mixed.

The main indicators of lubricants?
The main indicators of lubricating oil are: viscosity, viscosity index, pour point and freezing point, flash point and ignition point, ash, residual carbon value.
Viscosity is the speed at which lubricating oil flows at a certain temperature, and it changes with temperature. Generally, the viscosity at 40 ° C and 100 ° C is used as the standard internationally. Viscosity is an index for the classification and classification of various lubricating oils, which is of decisive significance for quality identification and determination.
Viscosity index is an approximate quantitative value that indicates the characteristics of oil products as a function of temperature. The higher the viscosity index, the less the viscosity of the oil changes with temperature.
3.Pour point and freezing point
The pour point is the low temperature at which the sample being cooled can flow under the specified conditions, and the freezing point is the high temperature at which the sample is cooled to a stop under the specified conditions, all expressed in ° C. The pour point or freezing point is a conditional test value and does not equal the actual flow limit.
The flash point of lubricating oil is a safety indicator for the storage, transportation and use of lubricating oil, and it is also a volatility indicator for lubricating oil. Lubricating oil with low flash point, high volatility, easy to ignite, poor safety, high volatility of lubricating oil, easy to evaporate and lose during work, and even cause the viscosity of the lubricating oil to increase, which affects the use of lubricant. If the flash point of a heavy lubricating oil suddenly decreases, a light oil mixing accident may occur. From a safety perspective, the safety of petroleum products is classified according to their flash points: those with a flash point below 45 ° C are flammable, and those with a flash point above 45 ° C are flammable.
The ignition point is also called the ignition point, which refers to the temperature at which a mixture of steam and air on the surface of a flammable liquid comes in contact with fire and the flame can continue to burn for no less than 5 seconds. Can be measured in the same standard instrument after the flash point. The flash point and ignition point of a flammable liquid indicate the possibility of explosion or fire, which has a great impact on the safety of transportation, storage and use.
6. Ash content of lubricating oil
The ash content of the lubricating oil is the residue (non-combustible matter) remaining from the oil of Quanzhou diesel engine after the lubricating oil has completely burned under the prescribed conditions. The ash content of lubricating oil is mainly composed of metal salts and metal oxides generated after the lubricating oil is completely burned. Additives contain higher ash. The presence of ash in the lubricating oil increases the carbon deposition of the lubricating oil during use. When the ash content of the lubricating oil is too high, the diesel engine oil and motor oil will cause wear of mechanical parts.
7.Residual carbon value
Asphaltenes, colloids and PAHs in lubricating oils are the main substances that form residual carbon. Therefore, residual carbon is an indirect indicator of colloidal substances and unstable compounds in oil products. The larger the residual carbon, the more unstable hydrocarbons and gelatinous substances in the oil, and the less, the less. Based on the size of the residual carbon, the tendency of the oil to form carbon in the compressor can be roughly determined. For lubricating oil materials, the residual carbon value can indirectly indicate the degree of refining of the lubricant. The deeper the refined oil, the smaller the residual carbon value.
