As we all know, the engine's blood is oil, and the consequences of not changing the oil on time are very serious. In addition, counterfeit motor oil will also shorten the life of the engine drastically. For a few hundred dollars of oil, the last tens of thousands of overhauls outweighed the loss, which reduced the car's salvage value and hurt its wallet. Today, the car said that he came to read the oil markings.

Oil properties

Many riders, especially those who play cars, like to study the various characteristics of engine oil. Indeed, under different temperatures and operating conditions, different brands of engine oil have different focuses on the protection of engine components. However, these features are only suitable for competitive players. For mass production vehicles for the general public, there is no need to consider such complicated features. Just follow the recommended viscosity on the original instructions. However, if your car environment is special, the engine oil number is still a certain amount of stress.

The meaning of the label

There are many viscosity-related articles on the Internet. In fact, we don't have to look at the temperature to make a choice. Many temperatures are just reference values. For example, if the weather in Beijing is based on the temperature standard, winter and summer oils must be used separately. How about the oil that was changed in that year? So it is not necessary to strictly follow the thermometer to change the oil, or that sentence, the normal car, in accordance with the specification of the viscosity, and those imported goods, anti-wear varieties, no need to spend money.

When to adjust the oil number

As mentioned earlier, the choice of the viscosity of the oil is related to the driving environment and personal habits. The higher the viscosity, the better the protection of the engine, but correspondingly, the fuel consumption and noise will increase accordingly. The rumors that the higher the viscosity of the engine oil on the Internet, the more quiet it is, is neither accurate. In fact, if you often get traffic jams, or if you like big foot throttles, driving is a quick temper, you should raise the oil viscosity of a level. Assuming the original factory is 5w-20, it is best to upgrade to 5w-30. However, generally only the viscosity is upgraded. It is not recommended to lower the original specification.

Brand choice

Not to mention how the quality of oil brands, big brands of oil are similar, there is no essential difference. However, the genuine brand on the map is indeed hard to find, the amount of fake oil has far exceeded the amount of genuine, so unless there is a reliable channel, it is not recommended to buy. Like Shell, the big names like Castrol also need to find reliable channels. Some small auto parts cities, so-called “monopoly”, do not believe. A bottle of fake oil does not have anything to do with the label. It is the industry’s conscience not to scrap the engine.

Finally, in a few words with you, the most suitable marking for the engine is the original factory setting, which is the result of repeated road tests and rig tests. If the use environment is harsh, often high or traffic jams, a thicker engine oil is needed to protect the engine. Regarding temperature performance, taking Beijing as an example, 5W is easy enough to deal with, and 10W is not a bad idea. If you often drive by yourself, there is a large temperature difference between the environment and 0W is recommended.
