In the process of buying engine oil, many car owners often hear others say: if economic conditions permit, it is better to use a fully synthetic engine, so what is good about fully synthetic engine oil and what is good for cars? In fact, many car owners are not very clear.
1. Good lubrication and cleaning performance
The quality of base oil in synthetic engine oil is relatively good. According to different functional requirements, adding different additives to the oil can achieve different effects, such as adding detergent and anti-wear agent to improve the wear and cleaning ability. Therefore, total synthetic oil is better than semi synthetic oil and mineral oil in terms of lubrication effect, anti attenuation and cleaning ability.
2. Good low temperature fluidity
The low temperature fluidity of synthetic engine oil is better than that of mineral oil. In winter, all synthetic oil can reduce the energy consumption of the car when starting at low temperature, thereby extending the battery life. At the same time, due to the good low-temperature fluidity, the lubricating oil takes less time to reach all parts, which can reduce the dry wear of engine parts during starting, thus extending the service life of the engine.
3. Less evaporation loss
The total synthetic oil is basically pure compound, and the boiling point range is relatively small under manual intervention, so evaporation is relatively small. At the same time, synthetic oil has good radiation resistance and chemical stability. Compared with mineral oil, it also has the characteristics of high oil film strength and less foam. Therefore, general 4S stores will recommend the use of fully synthetic oil, especially some CRRC.
4. Maintenance cost
The price of a barrel of conventional 4L mineral oil is mostly within 200 yuan, about 300 yuan for semi synthesis and about 400 yuan for full synthesis. Looking at the cost alone, full synthesis is more expensive, but in the long run, it is more economical in synthetic engine oil.
Because mineral oil needs to be replaced every 4000 kilometers, and the replacement mileage of synthetic oil can reach 10000 kilometers or even higher. Full synthesis can better protect the engine and prolong the service life of various components. Take minor repair as an example. The average working hours of 100 yuan and the oil filter of 40 yuan are converted into 10000 kilometers. The replacement cost of mineral oil is about 700 yuan, and the total cost of synthetic oil is about 500 yuan, which is obviously "cheaper" than synthetic oil.
If you plan to replace all synthetic engine oils, you must choose the viscosity and grade of engine oils according to the recommendations of the owner's manual, and then buy engine oils through formal channels, rather than low-cost low-quality engine oils.
