According to China Voice "Chaoguang News", after the domestic refined oil price was raised again, the gasoline price officially entered the "8 yuan era". In the face of high oil prices, how to save fuel has become the most concerned topic for car owners.
Recently, there are more and more fuel-saving products in many gas stations and auto parts cities in Hefei. Mr. Ji, a citizen of an auto parts city on Changjiang Road in Hefei, said that he only remembered to buy fuel-saving products after watching advertisements.
A salesperson of an oil-saving machine in Auto Parts City said that there are nearly 100 kinds of oil-saving products on the market. There are basically two kinds of fuel-saving agents and fuel additives for external use, and the prices range from tens of yuan to thousands of yuan. Many fuel-saving agents claim to be patented products. The salesman recommended a fuel-saving agent named "fuel treasure", and a bottle of 65ml was 30 yuan. He said that pouring a bottle into the fuel tank every time you refuel can clean the oil circuit and improve the combustion rate, but he couldn't answer how much fuel consumption can be reduced. In addition to the sales channels in the market, the reporter also conducted a search on Taobao. Various fuel-saving agents are also varied, and outlets with good sales volume can sell more than 3,000 sets of fuel-saving agents a month.
At a gas station on Wangjiang Road in Hefei, a private car owner, Mr. Wei, said that he had used such fuel-saving products to save fuel, but the effect was not satisfactory.
Teacher Li, who has 17 years of automobile maintenance experience, said that most domestic fuel additives are detergents, which have a certain effect on the cleaning of oil circuits. It can decompose the carbon deposit produced by gasoline combustion on the fuel nozzle and intake valve, so that gasoline can be fully materialized and burned. Fuel saving is only an indirect effect after the fuel is fully burned and the carbon deposits are removed. Saving fuel only through fuel additives will not have a significant effect of saving fuel.
Li Shifu conservatively estimated that there are many kinds of fuel-saving agents on the market at present, and 80% of them are not regular products. He said that inferior additives can not only fail to save fuel, but also damage the engine. External economizer has been popular for some time, but it is rarely sold in Hefei market at present because of its unobvious effect and relatively high price.
