Engine oil, the oil of the engine. The density is about 0.91×103 (kg/m3), which can lubricate and reduce the engine, assist cooling and cooling, seal leakage, rust and corrosion resistance, shock absorption buffer and so on. It is known as the “blood” of the car.
The engine oil consists of two parts, a base oil and an additive. Base oil is the main component of lubricating oil, which determines the basic properties of lubricating oil. Additives can make up for and improve the performance of base oil, and give some new properties. It is an important part of lubricating oil.
The engine is the heart of the car. There are many metal surfaces that rub against each other. These parts move fast and have a poor environment. The working temperature can reach 400 °C to 600 °C. Under such harsh conditions, only qualified lubricants can reduce the wear and tear of engine parts and prolong the service life.
The oil on the market can be divided into mineral oil and synthetic oil because of its different base oils (the vegetable oil is not counted because of the scarcity of production).
Synthetic oil is further divided into: total synthesis and semi-synthesis.
Lubricating base oils are mainly divided into mineral base oils and synthetic base oils. Mineral base oils are widely used and used in large quantities (more than 95%), but in some applications they must be formulated with synthetic base oils.
- Changing engine oil regularly or using good engine oil is an economical choice.
It is a good choice to use good engine oil and change engine oil regularly, but this often does not meet the economic choice of the owner. Therefore, choosing between a good oil for a long time or choosing a common oil to change the diligence is a problem that plagues many owners. Experts suggest that if economical considerations are concerned, for ordinary mid-range cars and economic cars, semi-synthetic oils can be selected and replaced at around 8000km. It is also conceivable to select fully synthetic oils and replace them at around 15,000km. They are all economical choices, It is worth noting that although it is very cheap, mineral oil should not be selected.
2, 4S shop’s engine oil is qualified, oil-proficient owners can also choose their own.
The engine oil in the 4S shop is more expensive. Is it suitable to change the oil in the 4S shop? This should be a difficult question for 4S shops and car owners, because it also involves a warranty issue. First of all, the oil provided by the 4S shop will definitely be qualified oil. For the owners who are not familiar with the oil, especially the owners of the vehicle under the warranty period, if it is not particularly proficient in oil, experts still recommend to go to the 4S shop to replace Motor oil. Of course, for car owners who are proficient in cars and oil products, they can make more appropriate choices based on actual conditions.
3, the turbine must use fully synthetic high viscosity engine oil
The lubricating oil of the turbine car not only bears the lubrication and heat dissipation of the engine, but also bears the lubrication and heat dissipation of the turbine, due to the role of the turbocharger, the mass and volume of the air entering the combustion chamber are greatly improved, the engine structure is more compact, the machining precision is higher, and the assembly technology requirements are more stringent. All of these determine the high temperature, high speed, high power, high torque, low emissions of the turbocharged engine. At the same time, it determines the internal components of the engine to withstand higher temperatures and greater impact, extrusion and shearing conditions. Therefore, in the use of oil, special attention needs to be paid. In terms of the choice of lubricating oil, there are two points that need special attention. One point is to choose high-quality lubricating oil. We recommend at least a full synthetic oil, preferably a lipid synthetic oil. In order to provide sufficient protection, another point is to choose a higher viscosity oil, 0-W30 is definitely the killer of the turbine, at high temperatures, can hardly provide any effective protection, we recommend to choose 5-W50 or 10W-50 product. On the turbine, you can choose Singapore Petroleum’s Saiwei 5-W50 grease synthetic oil, MOTUL 300V 10-W50 double-fat synthetic oil, Xinhui full power F1-A 10-W60, as a reminder, these high-viscosity lubricants are not suitable for general street cars. If you want to use these high-quality racing oils, you should choose a product with a lower viscosity grade.
