Is synthetic engine oil or synthetic engine oil used for car maintenance?

What kind of engine oil is the most suitable in our daily car maintenance? I believe this problem has troubled many new and old car owners. Today, let's take a look.

Of course, the engine oil we are talking about here is engine lubricating oil. At present, there are three kinds of engine lubricating oils for automobiles:

Mineral oil, semi-synthetic oil, fully synthetic oil. First of all, we can see from the price that the price of synthetic oil is the highest, so there is a certain difference.

Fully synthetic oil:

Engine lubricating oil synthesized by artificial chemical method. And different substances will be used according to different uses. Essentially, it uses better components in crude oil. Through chemical reaction, the ability of fully synthetic engine lubricating oil to resist external variables is naturally very strong, so its thermal stability, antioxidant reaction and viscosity change resistance are naturally much stronger than those of mineral oil and semi-synthetic oil. Whether it is the cleaning and repairing function of the engine, it is the best of the three oils, and the oil change cycle is also relatively long, which is basically twice that of mineral oil. The price is also quite expensive.

Semi-synthetic oil:

It is synthesized on the basis of mineral oil. Semi-synthetic oil is the transition from mineral oil to synthetic oil, with a lot of additives added. While ensuring the lubrication effect, the cleaning ability and oxidation resistance are significantly improved.

Mineral oil:

Oil is extracted directly, and the cost of mineral oil is usually relatively low. Mineral oil can guarantee the basic functions of lubrication, cooling, cleaning and repair. In addition, mineral oil is easy to oxidize, and its service life is still only 6 months or 5000 kilometers.

However, in the actual process of automobile maintenance, scientific maintenance still depends on the difference of automobile engines and the choice of engine oil.

If it is an old model that has been used for many years, such as second-hand Pu Sang, it is recommended to use mineral oil at this time. Through its high viscosity, it can repair the damage of the engine, make up the gap and make the car run better; If it is a naturally aspirated engine with low displacement, such as 1.6L power, it is recommended to use a semi-synthetic engine oil; If it is turbocharged, it is recommended to use all synthetic engine oil. Because the turbocharged car needs good fluidity and can cool the engine oil in time, this is the stage where synthetic engine oil plays.

Finally, I would like to remind you that scientific maintenance should be considered by yourself according to individual circumstances.
