Which brands of engine oil are generally better for American cars?

I am an American car, I have used Shell 5W30, used Mobil and Castrol, and later switched to the sub-unified titanium Heneng 7 series, and I instantly feel that the domestic engine oil is not worse than that of foreign countries, and it is cheaper. Mobil, Castrol, Shell are very good, pay attention to see if there is API certification on the bottle SN is the highest quality grade of motor oil in the world today, take 15W-40 and 5W-40 as an example 5W refers to the minimum temperature to adapt to (-30), and the latter refers to the ambient temperature to adapt to. Specifically, it corresponds to this:

The viscosity of lubricating oil is mostly marked by SAE and other grades, and SAE is the abbreviation of the English "Society of Automotive Engineers".

American car brands are divided into GM and Ford, and basically use the American version of the stupid Mobil.

Department of Dan Heng Bilie. As for what kind of engine oil to add, now after 2020, it will be China VI B emissions, and you can add lubricating oil suitable for vehicle sticky lift and standard. GM cars generally fill engine oil with GM Texelon certified engine oil, and the green mark is gasoline engine.

The blue sign is the engine oil used by gasoline and diesel.

Ford's models are also basically based on the Common Standard and then add Ford OEM certified oils.

If you really don't know what brand of lubricant to add, just choose the American version of Mobil No. 1 oil.

I really can't find a brand that can ask me to send it to you, but it doesn't have to be a Mobil No. 1 brand, or a domestic four-plus-five fully synthetic lubricant.

Domestic engine oil because.

There are few fakes.

U.S. cars tend to clean up their engine oil with good function, and you can also choose an oil that is labeled with the new GF5 specification. At this stage, the most suitable engine oil for American engines is Shell engine oil, Shell engine oil mainly promotes cleaning performance, which needs to be better than other well-known brands of engine oil in these aspects, and at the same time, it responds well and is relatively quiet in low and medium speed ratio driving force; In China, the main performance is somewhat poor when rotating at high speed, and the main performance is relatively average.

There are also Castrol engine oil and ** in the United States well-known brand Castrol oil is also very good, suitable engine oil in addition to the choice of well-known brands, important also depends on the choice of oil viscosity, because the American car is widely repentant motive organization high precision, the gap between the components of the mutual theme activity in the department is smaller, the engine operation is not as high as the German car, the demand for viscosity is lower, compared with the German car, its viscosity is smaller, so when choosing the oil, the viscosity should be smaller.

For American cars, generally choosing a 20 or 30 viscosity oil can give full play to the maximum performance of the engine, make the engine run more smoothly, and at the same time maintain the engine faster.

If the oil is too viscous by mistake, the fuel consumption will be increased, the rationality of gasoline and diesel will be weak, and the engine driving force will be lacking. However, if the manuscript is noisy like an old car (a very old car), a performance car, and a car that burns oil, you can use an oil with a viscosity of 40.

Millions of car purchase subsidies.
