Change the engine oil to the engine.

Many drivers change their oil very frequently when they care for their car. In fact, this is not the case. Many drivers are not very familiar with this aspect. Here are some of the cars that the small series have compiled for the riders. Some knowledge of engine and oil.

This is not the case. The reason is that to neutralize the acid produced by sulfur in fuels (gasoline and diesel) and to avoid acid damage to the engine, the new oil is alkaline and the oil is alkaline. When used, it gradually decreases with the use of the process, and alkaline oil can damage the engine.

ã€€ã€€ Â The base oil in the engine oil is neutral in nature, and its alkalinity is brought about by additives, including organic alkaline substances and inorganic alkaline substances. The alkalinity of the oil is measured by the total base number (TBN) .

The total alkalinity of high quality engine oil will not be modulated very high when it is new oil, but the total neutralizing acidity and the total amount of neutralization will be strong. The total alkalinity value will decrease slowly during use . Supports long oil change intervals and protects the engine from acid damage from fuel combustion or alkaline substances from the oil itself throughout its life cycle.

For similar reasons, the performance period of high-quality oil performance is not in the beginning and final stages of use, but in the middle period of its use period (80-90% of the platform period of its use period). The stage of performance.

The inferior engine oil often adds a very basic alkaline additive component to the engine oil, but its alkaline additive neutralizes the acidity and the total amount of neutralization. The total alkalinity value will decrease rapidly during use , and it is impossible to Supports long oil change intervals, and does not protect the engine from acid damage caused by fuel combustion during its entire life cycle. The oil itself can also damage the engine.

The use of inferior oil, the more frequently the oil is changed, the greater the damage to the engine caused by the alkaline substances in the oil.

Change the engine oil to the engine.

Therefore, the most important maintenance measures that are most beneficial to the engine are not to change the oil, but to choose high-quality oil.

In China, in fact, some international oils are highly adapted to China's national conditions: China's fuel oil needs to be alkaline and neutral, while Chinese maintenance vehicles are used to changing oil, and Chinese car owners like low prices, so they are lower. The cost of additives is in line with national conditions. Chinese car owners rarely detect the performance indicators of used oil (such as total alkalinity ). Chinese car owners rarely blame international, and Chinese car owners do not have the ability to fight internationally.

Therefore, these internationally sold oils in China will not sell the latest oils to the domestic market, especially for their low-end products, which are actually inferior engine oils according to European and American standards. Alkaline (TBN) is low cost. When the additive is obtained, the initial total base number is high and the total base value is rapidly decreased in use. It can only be used for a short period of time and has a certain degree of damage to the engine. These products have adverse effects even on the engine, and the quality and performance are the same as the domestic brands. The product is inferior to the product.

European automotive advancedness, environmental standards, and fuel standards are ahead of China. China's automotive emissions and fuel rating standards are based on the latest European environmental standards. Which companies can pass the standard certification and can reflect the company's level to a certain extent. .

With the increasing emphasis on environmental protection, on April 1, 2016, China has implemented fuels in accordance with the national five standards in the eleven provinces of the east. On January 1, 2017, it will sell all the national standards in the country. Fuel, while the domestically sold oil products have not been upgraded, MOL Group will bring the latest and most environmentally friendly oil products from Europe to China to serve the majority of car owners. MOL Group guarantees to the majority of users in China that all certified oils are produced in Europe under the same standards and are supplied to the world with the same standards. What is the oil used by Europeans and what can we use in China? Motor oil.

Change the engine oil to the engine.

The above is some of the relationship between the car engine and the engine oil that Xiaobian has compiled for the riders. I hope that the riders can learn more and make sure their car is healthy.
