Science Post: Car Superman takes you to understand fully synthetic and semi-synthetic engine oils

August 27, 2024

It is believed that many car owners are aware of the importance of car maintenance after buying a car for a period of time. If the car is not maintained in time, it will affect the performance and service life of the vehicle. Today, the car maintenance chain Superman will take you to learn about the relevant knowledge of fully synthetic oil and semi-synthetic oil to see what kind of oil you are suitable for.

Coptie: car Superman will show you about fully synthetic and semi-synthetic oils.

Fully synthetic engine oil VS semi-synthetic engine oil

What is the main difference between the two?

01 base oil is different

The total synthetic engine oil is a mixture of the third, fourth and fifth kinds of base oils; the semi-synthetic engine oils use the third kind of base oils; the selection of the total synthetic base oils is one level higher than that of the semi-synthetic base oils, and it is essentially a good component in crude oil.

02 applicable temperature is different

The fully synthetic oil is suitable for a wider range of temperatures. In the same working environment, the engine can be protected with lower viscosity, while the semi-synthetic oil requires relatively higher requirements.

03 different replacement cycles

The semi-synthesis process is changed once in half a year or 5000 km; the full synthesis is changed once a year or 10000 km in use.

04 different additives

The high content of TBN additives used in the full-synthetic oil makes the oil life longer and the cleaning effect of the engine enhanced; the TBN content of the additive used in the semi-synthetic oil is low, the oil maintenance cycle is shortened, and sulphide ash will be produced.

05 stability is different

Because of high-quality base oil and excellent additives, the full synthesis machine has less volatility, more stable, less friction and oil viscosity does not change with temperature.

06 the selling price is different

The price of full-synthetic oil is higher than that of semi-synthetic oil.

Fully synthetic engine oil VS semi-synthesizer

How to choose the same type? The choice of oil needs to be matched according to the performance of the car, but under normal circumstances, you can choose some semi-synthetic oil or all-synthetic oil can meet the needs of the car.

Coptie: car Superman will show you about fully synthetic and semi-synthetic oils.

Semi-synthetic engine oil is suitable for vehicle type:

Semi-synthetic oil has a wide range of applicability, if your car is a common economical car, and the annual mileage is not much, regular maintenance, then semi-synthetic oil is suitable for you. However, the harsh environment or long-term short driving should be reduced to change the mileage, in order to extend the service life of the car, this is your own grasp.

Full synthesizer applicable type:

In view of the fact that the performance of the fully synthetic oil is more excellent, if you have a luxury car brand or you are not short of money, you can choose the fully synthetic oil if you are willing to love your car. Turbine pressure, sports running, a large number of sedan chairs or SUV vortex supercharged type, must make full synthetic engine oil.

When the turbocharger starts to work, the engine torque will increase exponentially, and the oil film covering the friction parts of the engine will bear several times higher shear force than before, so that the all-synthetic oil can meet the requirement of high film strength.

All in all, total synthesis > synthesis > minerals.

Some car owners are reliable for this kind of oil as soon as they hear the word “half”. This is nonsense. The semi-synthetic machine is a mixture of mineral oil and total synthetic engine oil at 4:6, and its purity is very close to that of fully synthetic engine oil.

To sum up, if your car is worth less than 20W, semi-synthetic oil is more appropriate. After the specific, but also according to the car line and make habits to consider specifically. On, is the car super people to enjoy all the inside, hope to have something to gain for the family.
