The base oil in the oil is conventionally classified as mineral oil and synthetic oil. In countries where automobile consumption is very mature, the consumption of synthetic oil accounts for a large proportion of the total sales of lubricants, but it still has a small market share in China. Many owners do not understand the difference between mineral and synthetic oils. In fact, synthetic lubricants have more advantages than mineral oils.
Ordinary lubricating oil refers to mineral oil, which is the lubricating base oil that is obtained after the crude oil is purified and filtered, and the components that are suitable for use in the lubricating oil are selected and then further processed. Synthetic oil is a variety of complex production processes for chemical raw materials, to get the ideal molecular structure and distribution, the performance of all aspects of the final product has been greatly improved than the mineral oil, which can meet the higher performance of the lubrication requirements .
Suitable for wide temperature environments
Synthetic lubricants have a high viscosity index. Synthetic oil can be applied to a wide range of operating temperatures during normal use. Whether it is the cold winter in the north or the hot summer in the south, the synthetic oil can be handled with ease. Although the viscosity of synthetic oil is lower than that of mineral oil, due to its high viscosity index, the lubrication effect is better than that of mineral oil, and it can also achieve the purpose of energy saving.
Due to the better shear stability of synthetic oils (such as Shell's extraordinary Heineken shear stability is 3 times that of ordinary oils), this allows oils to maintain viscosity levels even at high temperatures and high engine speeds. Under harsh conditions, it can also provide strong thick oil film protection, maintain the lubrication of the engine, greatly reduce friction and reduce wear.
In addition, synthetic oil can achieve better fluidity at low temperatures, reducing engine wear. This means that in the cold or high cold conditions, the oil can quickly reach the various lubrication points, the engine can start instantly. Since the abnormal wear of the engine is largely caused by cold start, the use of synthetic oil can significantly reduce the cold start wear of the engine.
Cleaner, more environmentally friendly
Synthetic oil production technology can ensure that the oil has excellent thermal oxidation stability, greatly reducing the generation of harmful substances such as sludge, carbon deposits, and the engine to maintain the maximum degree of cleanliness. Take Shell Super Heineken as an example. The cleaning performance is 5 times that of ordinary mineral oil and can help the engine get better protection.
In addition, the superior oxidation resistance and high temperature stability of synthetic oils make the oil change period much longer than that of mineral oil, which can also reduce waste oil emissions. Due to the low loss of evaporation of synthetic oil, the consumption of oil products can be significantly reduced, thereby reducing the emissions of charcoal and hydrogen. And the synthetic oil is completely free of sulfur, nitrogen, phosphorus and heterocyclic aromatic hydrocarbons, can meet the higher emission requirements, and the damage of the oil to the human body is small, which all reflect its environmental significance.
