As long as it is higher than the quality level required by itself, it can be added. How can I choose a suitable engine oil? 1: Select a brand. There is an introduction about the influence of base oil on brand in front of this post. At present, the use of ester oil feels a little too scorched, and consciously tends to use full synthesis in the true sense, so PAO is the only choice, and Mobil is the earliest and most advanced company with the most patent monopoly on PAO base oil. Other more introductions about lubricating oil companies are not suitable for discussion here. First list the brands that can be seen and easily bought in China. Personally think that the brand with high credibility. Shell, Mobil, Castrol, Castrol, Motol Motol TORCO, Broaden the Red Line CONOCO ENEOS, Billion Energy, Fast Power, AMSOIL, Anceaux, fuchs Fox, Jinlibao, Jinlibao, of course, there are many other brands that have not been mentioned. Let's take a look at these famous brands in the world, which have a certain scale in the market and are easy to buy at home. With this 12 variety, we have a lot of choices, which is enough to make many people hesitate. Shell shell shell shell shell shell shell shell shell shell shell shell shell shell shell shell shell shell shell shell shell shell shell shell shell shell shell shell shell shell shell shell shell shell shell shell shell shell shell shell shell shell shell shell shell shell shell shell shell shell shell shell shell shell shell shell shell shell shell shell shell shell shell shell shell shell shell shell shell shell shell shell shell shell shell shell shell shell shell shell shell shell shell shell shell shell shell shell shell shell shell shell shell shell shell shell shell shell shell shell shell shell shell shell shell shell shell shell shell shell shell shell shell shell shell shell shell shell shell shell shell shell shell shell shell shell shell shell shell shell shell shell shell shell shell shell shell shell shell shell shell shell shell shell shell shell shell shell shell shell shell shell shell shell shell shell shell shell shell shell shell shell shell shell shell shell shell shell shell shell shell shell shell shell shell shell shell shell The Royal Logo is actually a product of Shell. An interesting phenomenon is that in the world's most famous BITOG forum, I rarely see anyone talking about Shell's lubricants, which may be the reason why it is difficult for Shell to squeeze into too many brand markets in the United States. Shell is very famous in China. It seems that more people know the brand of Shell than Mobil Mobil. There is a very simple reason. For example, there are only two McDonald's in my hometown, and KFC grandfathers are all over Hang Cheng. It's not that McDonald's is bad, but that KFC5 grandfathers have lived in Hang Cheng for more than three years when McDonald's moved to Hang Cheng. This is the result of preconceived advertising. Shell's patented XHVI III base oil technology can reach the performance of PAO polyolefin IV base oil, which shows that Shell has strong technical strength. Mobil Mobil can bluntly say that among the three brands of civil synthetic shell, Mobil Mobil and Castrol, American Mobil Mobil is the well-deserved boss. Regardless of industrial machinery, medical care, aerospace, food and ships. Mobil Mobil occupies a complete monopoly position, which is inseparable from its own technical strength and polyolefin PAO patent monopoly. There is an interesting line in the TV series "Wulong Mountain Scenic Resort Killing Bandits", "The gun polished by Mobil oil is really bright". You can also go home and ask your grandparents. Many kerosene lamps and gasoline lamps they used at that time were printed with the logo of Mobil. This is enough to show; The scale and strength of Mobil Mobil. Exxon Mobil is the holding parent company of Mobil Oil, and ESSO Esso is a branch brand of Mobil Oil. Castrol Castrol Germany was the first to make motorcycle lubricant and gasoline engine lubricant. In the movies of World War II, including the recent "Assassination of Hitler", German tricycles were labeled with red and green castrol. It can be said that Castrol has made great contributions to the German rapid mechanization forces. But before Castrol was acquired by British BP, one of the biggest differences between Castrol and Shell and Mobil Mobil was that Castrol was once the largest "independent lubricant manufacturer" in the world. The name means that this manufacturer does not produce crude oil itself, but buys other people's crude oil and processes it with its own unique technology to make its own lubricating oil products. Such manufacturers have a characteristic. If they want to occupy a place in the market, they must constantly innovate in technology. At present, the world's largest "independent lubricant manufacturer" is fuchs Flowserve. MOTUL Mott TORCO Broadens Red Line French MOTUL Mott American TORCO Broadens American Red Line Their history can be found online. They are also manufacturers with a long history. They are also manufacturers of professional track lubricants and famous ester synthetic lubricants. MOTUL Mott and TORCO Tuokuo and Redline provide customized high-performance lubricants for professional races and modified racing cars respectively, but these three manufacturers have their own characteristics. MOTUL is characterized by high-quality ester-based oil (mainly chemical synthesis of castor oil and ethanol), TORCO is characterized by strong additive MPZ (organic molybdenum), and REDLINE is characterized by chemical synthesis of polyester POE base oil from animal and vegetable fats and ethanol. Although these three characteristics all aim at high performance, they all seem to achieve the same goal, but there are still differences. As for their respective fist products, MOTUL 300V is synthesized by diesters, and its ability to resist viscosity decay at high temperature is stronger than that of monoesters. At the same time, they take into account the advantages of good low-temperature fluidity of monoesters. MOTUL's lubricating oil always feels stable, but the disadvantage is that it won't give you a crazy feeling. TORCO's fist product is SR-5, which is a synthetic ester. Whether it is polyester or not, the manufacturer has not made it clear, but what really makes SR-5 tough is its organic molybdenum additive MPZ. In theory, MPZ can reduce friction by 40%, thus obtaining less oil resistance. However, the shortcomings of molybdenum can easily lead to engine oil blackening quickly, and molybdenum can only be turned into organic molybdenum through the synthesis of phosphorus and zinc, so environmental protection is a problem (although I know that the owner who pursues high-performance lubricating oil is not). As for the famous red line, it is the base oil of polyester. The advantage is that it's crazy when it's hot and bad when it's cold. Of course, professional competitions do not consider cold car preheating. Speed and horsepower of Subba ENEOS Billion Energy Japanese Subba Speed and horsepower should be said together with MOTUL Mott, and the reason for separating it is to put it together with ENEOS Billion Energy of Japan. Suba Extreme horsepower has its own unique patent addition technology SPL FM, which has always been the favorite object of Japanese modified cars. ENEOS Yineng is a lubricant manufacturer that produces basic crude oil, and also a manufacturer that produces BT 0W50 (original oil of Mitsubishi EVO X) in the field of civil total synthesis at present. The domestic market of these two manufacturers is very small, and the price is also very small. However, there are few related technical materials published on foreign websites, so we can't say too much information. AMSOIL Anceaux) AMSOIL Anceaux of the United States just entered China last month, and BITOG spoke highly of this oil. However, it will take several months to know the fuel quality and driving environment in China. The biggest feature of this oil is the extremely long-term effect of BT, and the bottle body and machine filter are marked with 25,000 miles = 40,000 kilometers for oil change. I don't think anyone in China will really try this unless the car is not their own. Conocophillips and Tacumi saw Conocophillips' booth in the United States when they went to see the modified auto show last year. ConocoPhillips did enter the China market with a low profile. Conocophillips' evaluation is very cost-effective, and he is willing to praise it for its high cost performance. Its subsidiary product 76 platinum semi-synthetic 5W30, TB is only 35 and 4L, but the price of yellow shell HX5 10W40 mineral oil shows how high its cost performance is. FUCHS FOSS Germany FUCHS FOSS is like a shell, which can synthesize three kinds of base oils as well as four kinds of PAO base oils. It is a technical manufacturer with reasonable price. The biggest reason why FUCHS FOSS is not popular in China is the failure of the market. Its supersynthesis was once sold to more than 400 gundam 100, and the chaotic market discouraged many oil companies. The situation in Foss, fuchs. . . . . But your failure in marketing and management is enough to cover up all your advantages. Jinlibao Jinlibao is characterized by good wear resistance. Recently, it has participated in some exhibitions in China very diligently. After 10 years of efforts, it finally entered the automobile market vigorously. I worked hard in the industrial market for many years before. Although its popularity is not as good as that of Mobil Shell, it also has a certain popularity in China. Many steel mills and gear factories generally choose domestic products, and Jinlibao will definitely be the first choice. Now gradually turning to the automobile market, the cost performance is similar to that of ConocoPhillips, and the wear resistance can be said to be difficult to meet opponents, and even Mobil Shell has to look forward to it. Well, these brands have a certain scale, a certain history and a certain technical strength. If TX is completely unfamiliar with lubricating oil, it can choose the viscosity model suitable for itself among these brands under the condition of ensuring the authenticity and reasonable price, and feel free to use it. Personally supplement several domestic common lubricant manufacturers, namely: Great Wall, Kunlun and Uni-President. Although Uni-President was acquired by Shell, its product line can still be seen in the market, but the production company was changed to Shell Uni-President. References:
