Which is the best ranking of domestic motor oil brands?

The quality of the engine oil has little to do with the brand, because there are too many engine oils in China, and the bigger the brand, the less engine oil there is. Therefore, the most important thing in choosing an engine oil is quality and composition, not brand. 

The brands on the above ** are all famous brands, but whether you can buy them really depends on your personal luck. Although there is a flood of fake engine oil, some of the quality of the fake is still okay, although it is not as good as the real thing, but it does not affect the normal use of the vehicle, so the owner will not have much feeling. China's fakes are so rampant that even the so-called identification methods may be various, and even fakes have their own identification methods, and many people can't tell what is real and what is fake.

Personally, it is recommended that it is best to buy or maintain it in a large fast insurance store or 4S store, because the larger stores should try it before purchasing to ensure the rights and interests of customers. Some conditions can be maintained in the 4S shop, although it is more expensive, but the heart is steady.

The best in the ranking of domestic engine oil brands should be the Great Wall engine oil, but no matter how good it is, it is also domestic, and I personally feel that it is still easy to use imported, and I changed it for imported GT magic red engine oil, PAO's base oil plus liquid molybdenum additives, the quality is much better than the general three types of fully synthetic engine oil, and the car is much smoother than before.

The top 10 engine oil brands in China are Shell, Mobil, Castrol, Sinopec, Kunlun, Total Total, JAMA, Fuchs, Kroneseder, and Chevron Jinfuli. In the ranking of the top ten domestic lubricating oils, the top three lubricants are Great Wall lubricating oil Sinopec, Kunlun lubricating Kunlun, and Tongyi lubricating oil.

1. Mobil Mobil.

Among Mobil oils, Mobil One Series oils are top-of-the-line and can be divided into three categories, KingEngine Performance Series, Classic Performance Series, and Custom Series, each of which is further divided according to viscosity grade.

Mobil oil has a good overall performance and can play a good role in protecting the engine, so that the performance of the engine can be maximized. At the same time, the main characteristic of Mobil motor oils is longevity.

That is to say, the oil replacement cycle is long, Mobil uses the exclusive poly-olefin base oil, the molecules are neatly arranged, has good oxidation resistance and high temperature resistance, its viscosity changes little, it is more suitable for long-term use, in addition to the brand of oil quietness is also good.

2. Great Wall lubricating oil sinopec

Great Wall engine oil is based on the series of Jinjixing series of lubricating oil, the overall performance has excellent low-temperature start-up and high-temperature lubrication performance, suitable for all-weather use in various regions; The low viscosity value reduces frictional resistance and prolongs the service life of the engine; Improve fuel economy and extend the service life of three-way catalytic converters; It has excellent engine cleaning ability and effectively suppresses carbon deposits and sludge generation.

Shell, Mobilmobil, Great Wall, Kunlun, Uni-President, Total Total, Castrol Castrol are all very good, they are all famous brands in the market, you can refer to them.

In terms of domestic engine oil, Great Wall engine oil and Kunlun engine oil are better among domestic brands.

As long as the domestic engine oil is genuine, it is not a fake and shoddy product. There are a lot of counterfeit and shoddy engine oils on the market, all of which are counterfeit and counterfeit many well-known big brands. Therefore, when choosing engine oil, you need to be professional.

The most mainstream is the engine oil brand under the "two barrels of oil", that is, Kunlun under PetroChina, and the Great Wall brand under Sinopec. This is the most common domestic independent engine oil.

Then Lopal engine oil, as a listed company, is also a giant. Regardless of production volume and enterprise size. It is also a relatively mainstream regular brand.

Of course, there are still many domestic engine oil brands, such as Aojina, which is supplied to Tianjin FAW, and Tong, which was annexed by Shell.

1. Compton for the Antarctic expedition team, etc.

Hope it can be adopted, thank you.

The first-line brands include Great Wall, Kunlun, Longpan, Ogina, and Tong.

1. Compton et al. Among them, the Great Wall and Kunlun are state-owned enterprise brands, and the others are private enterprise brands, with reliable quality and service, they have won part of the market, and the advantages are: moderate and reliable quality.

The domestic engine oil brands are as follows: 1. Great Wall: Great Wall lubricating oil In recent years, in the Chinese lubricating oil market, the total sales volume of Great Wall lubricating oil ranks first, of which the sales volume of packaging oil is the first, and automotive oil and industrial oil have also grown significantly.

2. Kunlun: Kunlun Lubricating Oil PetroChina Lubricating Oil Co., Ltd. is a professional lubricant company integrating production, research and development, sales and service.

3. Unification: the myth of the unified lubricating oil industry, once the leading brand of national lubricating oil. The production and sales of "Tongyi" brand lubricant series products are well-known in the domestic market, and the products cover many petrochemical fields such as automobile oil, motorcycle oil, industrial oil, construction machinery oil and grease, brake oil, antifreeze, car care products, etc.

4. Lung Poon: As a fast-growing national brand, Lung Poon lubricating oil belongs to Jiangsu Lung Poon Science and Technology Lung Poon lubricating oil series products, including gasoline engine oil, diesel engine oil, gear oil, anti-wear hydraulic oil, antifreeze, brake fluid, grease, car maintenance products, etc. Hope, thank you.

I think the domestic car oil or Lopal engine oil is better, we can choose fully synthetic engine oil, it can increase the power of the engine and reduce the wear of the engine, and the price is not high.

Which brand of domestic car engine oil is better? I think there should be many brands of domestic car engine oil, you can check it on the Internet yourself.

The electrostatic precipitator of the second burning machine head was transformed in 2009. The original factory site is limited, only the location of the new dust collector on the east side of the original dust collector, and the other 1 needs to be newly built at the original dust removal location. Since the electrostatic precipitator of the sintering machine head is the best production equipment, in order to reduce the impact on the production time.

Construction plan: build a new dust collector in the open space on the east side, and connect the east flue to this dust collector for the first time after the dust collector is completed. Dismantle the original Dongtai dust collector and build another dust collector, after the dust collector is completed, the second contact will be connected to the west flue to the new dust collector, the second burner head electrostatic precipitator was completed at the end of 2009, and the design emission concentration of the dust collector is 50mg m3.

The electrostatic precipitator of the second and third burning heads can meet the new national standards under normal production conditions. However, the emissions of western burning and new burning cannot meet the requirements of the new national standards. Domestic and foreign sintering head flue gas purification all use electrostatic precipitator, the new national standard requires the emission to be less than 50mg m3, which is difficult to achieve at present, although the electrostatic precipitator increases to 4 electric fields, but the sintering head electrostatic precipitator is affected by the process temperature, humidity, specific resistance is fluctuating, and the emission of sintering head electrostatic precipitator is also fluctuating, especially the fluctuation of sintering production, sintering machine start-up and shutdown, etc.

At present, more than half of the sintering machines in the country have completed flue gas desulfurization, that is, the dust in the flue gas has been further processed by the desulfurization process after passing through the electrostatic precipitator, and the exhaust flue gas can fully meet the new national emission standards. According to the requirements of the national "Eleventh Five-Year Plan" emission reduction plan, the ironmaking plant began to adopt the Danish rotary spray semi-dry desulfurization process in 2009, and successively completed the flue gas desulfurization facilities of 6 sintering machines, and the dust emission of 6 sintering heads of the ironmaking plant after desulfurization bag dust emission of 30mg m3 fully meets the requirements of the new national standard. In order to meet the requirements of the new national standard of 30mg m3, the existing electrostatic precipitator can be increased and transformed

The first is to increase the circulation area, reduce the wind speed of the electric field, and prolong the residence time of the flue gas medium in the dust collector, which is equivalent to dismantling the existing dust collector and widening and heightening it on the original basis; The second is to increase the number of electric fields, the original dust removal is retained, and the original inlet or outlet bell mouth is removed and increased to an electric field, so as to increase the area of the dust collection plate of the electric field, prolong the time for the flue gas to stay in the electric field, so as to improve the dust removal efficiency; Another solution is the electric bag reform scheme: retain the original electrostatic precipitator foundation, shell, ash hopper, bell mouth and ash conveying system, only remove the plate line and rapping system of the original electric field, and remake the upper box to install the cloth bag, but due to the increased resistance of bag dust removal, the original motor needs to be increased. The above scheme is comprehensively considered from the stability, effect, investment, construction period, site, etc., and the electric bag modification scheme is the best.
