News background: The cost of car prices rose sharply Starting from this month, the domestic wholesale price of refined oil will be raised again by RMB 400/t. The Guangdong Provincial Price Bureau subsequently announced the retail price of refined oil in the province. The national III standard 93 gasoline rose to 5.76 yuan, up 0.32 yuan per liter; III Standard No. 97 gasoline was 6.24 yuan, up 0.34 yuan per litre. The reporter saw in the automotive supplies market that all kinds of fuel-saving products were again launched by businesses. Many large auto parts and supplies manufacturers and service providers frequently launch various types of “economizer products†to the market, such as green fuel-efficient tires and fuel-efficient lubricants. Are these products really useful? Green tires save fuel 70% of Michelin's tires are fuel-efficient green tires, such as Michelin Energy XM1 fuel-saving tires, Michelin Bray tires and so on. Vrujo claimed to save 1.4% of fuel compared to its previous generation. Taking a 30,000km-a-year vehicle as an example, it is equivalent to enjoying 400km of fuel-efficient travel every year. However, this does not mean that these “GREEN X†logos are used. The tires will definitely save fuel. Miao Yiming, product manager of the Michelin (China) car and light truck tire replacement market, told everyone that this also needs to be combined with the driver's driving habits and road conditions. The fuel savings data from the tire test were obtained under the same conditions of the test environment. Fuel-efficient green tires are relative to ordinary tires. For example, silicon-containing tires have excellent grip and can generate less energy loss, thereby reducing resistance and wear, achieving better fuel economy than ordinary tires, and extending tire life. Tire filling nitrogen and oil saving effect is not great The quality of tires determines the driving comfort and safety of the vehicle. The tire filling with nitrogen or air filling is a hot topic in recent years. In the role of the product, consumers have fallen into a misunderstanding that nitrogen-enriched gas must be able to save fuel. Some beauty service stores in Guangzhou have already started to provide nitrogen service. Technical experts from Michelin China said that the most important role of nitrogen is to provide better comfort and safety, maintain stable tire pressure and improve the stability of tire running; nitrogen has low audio conductivity and can effectively reduce tire noise. , Improve the quietness of driving; At the same time, nitrogen can reduce the possibility of irregular abrasion of the tire, such as crown grinding, shoulder grinding, eccentric wear, etc., in the increase of tire life, while effectively reducing the chance of high-speed tire burst . Experts also said that nitrogen is not a panacea. It can only protect tires to some extent. As for the fuel-saving effect, from the standpoint of tire pressure stability will play a role in fuel conservation, but it is not an effective fuel-saving method. The role of lubricating oil can not be cheap In the outer shell of many lubricants (commonly known as oil) products, it is not difficult for consumers to see the words “provincial fuel costs†and “economizing fuelâ€. Unipec displayed the “fuel-saving†sign on several classic products it launched, and provided the words “to achieve a fuel saving of 1.5% and a power increase of 4.5%†in order to prove that these products have passed international practical tests. High fuel economy. Master Zeng from Guangzhou Honda's repair shop stated that the use of good quality lubricants (such as Castrol's magnetic protection lubricants, etc.) can extend oil change intervals and achieve long-term fuel savings. Of course, if you think that the use of lubricants is almost okay, as long as the oil is enough for work, as can be achieved to protect the engine and saving fuel, then it is equivalent to chronic suicide, and ultimately will lead to scrapping the car. The vehicle's manual will specify the lowest viscosity lubricant that the car can use. The lower the viscosity of the general lubricant, the more labor-saving the engine and the more fuel-efficient the vehicle is. The use of SJ or SL grade oils also has a certain fuel economy. According to the analysis of the master chef, the oil-reducing lubricating oil does not mean that it is resistant to burning, but refers to the fact that such lubricating oil, through the addition of additives, ensures that the engine components are fully lubricated under the premise of moderately reducing the viscosity and reducing the resistance to the piston, thereby achieving Relatively oil-efficient effect. However, it is also a risk to choose a lubricant with low viscosity. For example, in the process of high-speed or long-distance driving, ordinary SAE lubricants with low viscosity are more likely to suffer from poor piston sealing. High-end lubricating oil products use lubricating oil additives, which can maintain a relatively low viscosity while ensuring a high stability of the lubricating oil, which is relatively more fuel-efficient. In particular, some ILSAC-certified lubricating oils can have relatively significant fuel-saving effects. . Reporter's notes: Many consumers place a "miraculous" expectation on the "fuel-efficient" effect of product promotion. However, facts may not be able to do so, and they will enter into over-reliance on product misuse. The fuel-saving effects of many products are “relatively speakingâ€, and specific to each consumer, because the operating habits are not the same, it may not be able to truly achieve the “oil-saving†effect of certain products. Therefore, for the consumption of “economized†products, consumers need to first analyze rationally and then do what they can. Take tires as an example. If someone wants to spend a few thousand dollars on a cheap car to install a fuel-saving tire in order to covet a high-end brand's “fuel-efficient†effect, it seems to be too wasteful. Whether it is the tire manufacturer or the lubricant manufacturer, the main purpose is to attract customers to buy their products, and "fuel-efficient" is indeed one of the most eye-catching words in recent years. Although inevitably, some businesses will add “fuel-efficient†words to advertising in order to expand sales; but if they are all gimmicks, they are also too arbitrary. During the several new product launches attended by reporters, manufacturers put out various test data and videos to prove that the new generation of products has progressed in comparison with the previous generation of products, but not by simply comparing with competitors, but only objectively. Compared with their own old products, they tell consumers that "our R&D technology is further advanced." The price and the service life of new products are all there, what the effect is, and consumers use what they know, instead of developing the habit of “overly relying on products to save fuelâ€.
