The most important part of a car should be the engine. If the engine needs engine oil most, and there are different types of engine oil, what's the difference between semi-synthetic engine oil and whole synthetic engine oil? There is no oil mixed with any minerals in synthetic engine oil. Relatively speaking, the whole of synthetic engine oil is better, because the manufacturing is also stricter.

Like those better cars, all synthetic engine oil will be used, because all synthetic engine oil is much better than semi-synthetic engine oil in anti-fall ability and stability, so it will have more horsepower space than semi-synthetic engine oil, and the damage to automobile engines will be less. Besides, many cars are equipped with turbocharged engines now, so the use of synthetic engine oil will better meet the demand for ink, so since synthetic engine oil is better than semi-synthetic engine oil in all aspects, the price is definitely more expensive than semi-synthetic engine oil.

In addition, the base oils used in these two types of oils are still different, and the replacement cycle is still different. Generally, synthetic engine oil is not suitable for the weather with particularly large temperature difference between day and night, but suitable for the more common weather. Of course, what kind of oil to choose depends on the income of the owner and the condition of the car. In addition, the maintenance of the car is more important and can prolong the service life of the car. The engine also needs attention. Good maintenance can save you a lot of oil.
