Is it useful to add fuel treasure?
Fuel treasure, Fuel King and Fuel Essence, which are highly recommended by some gas stations and auto repair shops, are said to be environmentally friendly and fuel-efficient, and can also protect automobile oil circuits. What kind of chemicals are they? Are they good or bad for cars?
Yesterday morning, CCTV financial channel "Financial Information" and "Consumer Proposition" columns exposed that such products were "actually useless" through interviews with reporters and testing by relevant departments.
CCTV reporters recorded unannounced visits to some gas stations in Beijing: so-called "fuel cleaning additives" and other products can be seen everywhere, and the staff of gas stations sell well. Some oilers said: "The car is more energetic, the throttle is light, the idle speed is stable, the engine is lubricated, and the oil circuit is cleaned" and so on. Some said: "It is mainly to clean up the carbon deposit and make the gasoline burn more fully in the cylinder, which will save fuel relatively." Some people even say that "the same box of oil, with fuel treasure, can run 100 kilometers, and 200% works."
However, CCTV survey found that in recent years, vehicle gasoline used fuel detergent, and fuel treasure and other products sold in small bottles at gas stations were one of the fuel detergents. As early as 20 1 1, it was pointed out in the "Control Standard for Hazardous Substances in Vehicles" issued by the Ministry of Environmental Protection that gasoline should be added with gasoline detergent meeting the "GB 19592" standard, that is to say, gasoline produced in China has been added with "fuel detergent" before being sent to gas stations.
Yue Xin, director of the Automotive Fuel Emission Laboratory of china environmental science Research Institute, said: "At present, the gasoline quality in China, especially in Beijing and other areas that have adopted the national five standards, is quite safe and reliable. In principle, vehicles do not need to add fuel detergent, and consumers do not need to buy this small package (fuel treasure) to add to the fuel tank. " He also stressed: "Excessive or improper use of fuel treasure is even harmful." If it is used excessively, it will increase the carbon deposit in the combustion chamber while removing the carbon deposit in the intake valve of the engine. If it is added too much, it will even lead to engine knocking (that is, the gap between the cylinder and the piston becomes larger, and the piston does work), knocking (extremely intense combustion after oil-gas mixing), and vehicle exhaust emissions will also deteriorate.
experimental result
You can't see fuel saving, and the exhaust emissions are higher.
Fuel treasure has three selling points: "saving fuel, reducing emissions and cleaning the oil circuit". Is that so?
CCTV reporters, with the help of professionals, conducted environmental protection tests on fuel treasure's emissions. Before adding fuel treasure, the NOx emission value of a car was about 80, but after adding, it was driven for 2 hours. Theoretically, fuel treasure should be fully mixed with gasoline and put into the cylinder for combustion. At this time, we can know whether there is any change by monitoring the waste gas again-at this time, the emission value of nitrogen oxides has increased to 90~ 100. We should know that nitrogen oxides are the chief culprit of smog and air pollution, and are an important promoter of the increase of PM2.5 content in the air and the aggravation of acid rain.
Ni Chuning, an automobile maintenance expert who participated in the test, said that after joining fuel treasure, the power of the test vehicle has not changed significantly, and the instantaneous fuel consumption has not changed significantly. This result is also reflected in another SUV that participated in the test.
Few people can play a cleaning role.
In order to verify the actual function of fuel treasure more accurately, CCTV reporters watched a more sophisticated experiment in the automobile fuel emission laboratory of china environmental science Research Institute. This standardized experiment, which is specially used to verify the vehicle fuel detergent, uses Mercedes-Benz M11engine, and works continuously on a special frame for 60 hours, consuming 320 liters of gasoline, and obtains the results.
Yue Xin, director of the laboratory, said that they had done more than 100 experiments and verified more than 100 brands of fuel detergent. From the actual effect, some fuel treasure cylinders will still be dirty after use, some are medium (dirty) and some are relatively clean. After adding some inferior fuel treasure, viscous grease was formed on the piston. Such a fuel treasure will not only fail to clean and maintain the vehicle, but will block the valve and seriously damage the engine.
Although all the experiments are not over yet, it is impossible to announce the qualified proportion of truly effective fuel detergent, but according to the on-site observation of CCTV reporters, only a few can play a cleaning role. ...& gt& gt
Question 2: What are the benefits of adding fuel treasure to cars for a long time? Just use it regularly, without adding it for a long time;
It is a cleaning detergent, which has obvious cleaning effect on the deposits in the fuel intake system of the automobile, especially in the fuel nozzle and intake valve, and will not have adverse effects on the engine.
If you have to add it, add it every 1W km, saying it has cleaning function.
Question 3: Is the car refueling treasure really useful? Really useful, just like adding a filter to your tap water;
Super-beautiful * * crystal lubricating oil is used for burning engine oil, not for burning engine oil, which is wear-resistant and repairable;
I would like to ask Baidu to know the task: please adopt it, thank you! ! !
No matter what kind of oil, as long as the wear resistance is good;
Diesel, gasoline, natural gas and liquefied petroleum gas engines are universal, with fast speed increase, no oil burning and wear-resistant repair;
/kloc-mineral oil sl/cf15w/40 for cars below 0/00000 yuan;
65438+10-200,000 yuan car, using semi-synthetic engine oil SM/CF 10W/40.
For vehicles with more than 200,000 vehicles, all synthetic engine oil SN/CF 5W/40 shall be used.
The engine oil for diesel vehicles and natural gas liquefied petroleum gas is 18 liter, which is generally CI-4 15W/40 and CH-4 15W/40.
Many BMW cars that burn engine oil use super-beautiful crystal lubricating oil, but to my surprise, they no longer burn engine oil, because it is nano anti-wear repair engine oil; At the same time, the engine oil of carts and trucks is also very powerful; Directly approved by the manufacturer;
You use inferior engine oil, which is caused by poor wear resistance. Not wear-resistant, it will burn oil soon. With super beautiful * * crystal lubricating oil, the wear resistance is good, which will improve a lot.
Using engine oil with good wear resistance is basically difficult to wear and will not burn engine oil for life;
You still believe in the original factory? The original factory is basically qualified; Absolutely not the best;
Before changing the engine oil, it is best to clean the carbon deposit with the internal cleaning agent of the engine;
If you feel that the car is not strong, you can also add 60 kilograms of gasoline or diesel to fuel treasure, which is made by Sinopec Chaomei;
Question 4: Question 5 Expert: Do you want to add fuel treasure to the car? This is actually the confusion of many car owners. Every time I enter the gas station, there is always a staff member who enthusiastically asks, "Do you want to add fuel treasure?" Most people ignore this kind of sales promotion, so if you were told that the senior manager of a 4S shop in Hangzhou said that he often drives fuel treasure, would you choose to try? Dozens of yuan, 4S shop 100 yuan a bottle.
Is fuel treasure useful? The price difference of fuel treasure in the market is several times. What's the difference in efficacy? Drivers also have many questions about gasoline additives. A few days ago, we consulted a number of senior maintenance experts with the problems that riders are most concerned about.
Guo Peng, Service Director of BMW Jinhu: Theoretically, it will definitely help. In the early days, the main ingredient of fuel treasure was detergent, which was used to clean up carbon deposits. With the addition of detergent and high-clean gasoline to the finished gasoline, the main component of "fuel treasure" is gradually changed from detergent to combustion improver, which can improve the combustion efficiency and temperature of the engine, increase the pressure in the engine cylinder and improve the engine power. Especially when the car is tired, old, loaded and gone far, it feels more obvious. In addition, adding fuel treasure can improve atomization and save fuel; Corrosion protection, rust prevention, lubrication and engine protection; Reduce noise, reduce wear and prolong engine life; Eliminate black smoke and reduce emissions.
Hangzhou Zhongao Automobile Palace Technician: Japanese and Korean cars and domestic cars don't need to be added, because they are not particularly sensitive to oil quality. American cars and German cars emphasize driving, handling and speed. Faster acceleration requires more fuel and air. According to the ideal air-fuel ratio 14.7∶ 1, adding one more fuel requires 14.7 times of air, which easily leads to the phenomenon of insufficient air and insufficient combustion, with more carbon deposits, and the quality of engine oil in Europe is generally better than that in China. Therefore, it is better to add European and American cars to fuel treasure.
Guo Peng, service director of BMW in Hangjinhu: High-end cars with high compression ratio, such as 7 Series and X Series, are the most obvious maintenance of the company in recent years. Basically, every car owner will accept the addition of fuel treasure. Especially before holidays, sales in fuel treasure are particularly high.
Hangzhou Zhongao Automobile Palace Technician: No, carbon deposition will damage the engine, aggravate wear and tear, reduce power, increase noise and increase fuel consumption. Regular maintenance of oil circuit and intake and exhaust system can reduce carbon deposition, but it also increases a lot of expenses for car owners. The more economical way is to add five times in a row and then stop for about 7000 kilometers.
Guo Ming, service director of Jinhu BMW: You can also add fuel treasure every other tank of oil.
Hangzhou Zhongao Automobile Palace Technician: fuel treasure is just like a health product. There is no carbon deposit problem in the vehicle, and there is no need to add the newly maintained vehicle. Drive less and drive more slowly. Once you stop using it, there will be no problems, but it will feel less exciting than before. Of course, adding fuel treasure, like health care products, can improve immunity and keep vehicles healthy for more time, but it can't cure the problem. Vehicles with serious carbon deposits still need to go to the repair shop for professional disassembly and cleaning.
Hangzhou Zhongao Automobile Palace Technician: fuel treasure is a product with very high added value, but the difference in composition and effect is not too big. However, the added value of brands is very high, and the prices of products certified by the state are generally higher. The market is still full of fake and shoddy products, which can be identified by the following measures:
1. Is this product patented? What is the patent number? Can it be retrieved from the website of China National Intellectual Property Administration? Because fuel treasure itself is a high-tech product, really good products must have their own patented technology.
2. Does the product have a clear inspection report from the national authority? (Note: At present, there are some authoritative organizations in this field in China, such as Ministry of Communications, Ministry of Environmental Protection, China Petrochemical Research Institute, etc.).
3. Comprehensively investigate the basic situation of product manufacturers.
Question 5: What are the advantages of adding fuel treasure? Hello, to your question, you said fuel treasure sold at the gas station. It is understood that fuel treasure is a cleaning agent, which has a remarkable cleaning effect on the deposits in the fuel intake system of automobiles, especially the injectors and intake valves, and will not have adverse effects on the engine. But you can't clean the throttle. Fuel treasure can gradually clean up the deposits in the air intake system when the car is running, which can significantly improve the fuel atomization effect, make the combustion more complete, improve the thermal efficiency, and thus achieve a certain fuel-saving effect. Regular use of fuel treasure can effectively remove the deposits in the automobile fuel system and keep the air intake system and spark plug clean, thus reducing the maintenance cost of the fuel system and prolonging the service life of the vehicle. If you have never used a car with fuel detergent, but if your car has been used for a long time, I suggest you be cautious! In order to avoid the cleaning effect of fuel treasure, some carbon deposits in the engine were cleaned. If the injector is blocked, the engine working condition may be reduced, resulting in unstable idle speed of the engine. I hope my answer is helpful to you.
Question 6: Is fuel treasure useful? I've been paying attention to the dragon fuel treasure for a long time. After all, it belongs to China Petrochemical. He is a big businessman. I read a lot on Taobao. It's a bottle of 6.5 yuan's China Petrochemical Gas Station. The price of a bottle of Taobao is too attractive. I tried to buy it on Taobao for a long time. Taobao has taught me many ways to tell the truth from the false. But I'm still afraid of buying fakes. I suddenly stopped at Taobao this morning. However, it was found that none of the sellers selling Hailong fuel treasure were goods from Taobao Mall. Since it is a real Taobao, why not give them certification? And they are not authorized by China Petrochemical, so it is judged that the goods on Taobao are all fake. Later, I wanted to pull J8 and buy it at a regular gas station. I bought a bottle of 30 yuan at the gas station at noon, and then I added half a bottle of 200 yuan oil. I ran a short distance and didn't feel anything. It can be parked downstairs for more than 2 hours, so the second startup effect will come out. Every time the starter turns on, there will be a starting sound, usually three coughs. Cough. Cough. When it started, I felt scared. Why did it get so hot so quickly? Because I have been sailing for two years, how long does it take for the ignition motor to turn several times? I don't know if it's fuel treasure. So I started to get used to it. Turn off the engine. I was still coughing when I lit the fire. I bumped into it several times in the afternoon and caught fire with one sound. See the effect tomorrow morning and freeze the car outside for one night. I advise all shipmates, fuel treasure, Dragon of Taobao. Although I have never used it, I'd better not buy it. )
Question 7: Is it useful to add fuel treasure to cars? Fuel treasure's function is 1, which automatically cleans the engine fuel system of a driving car to remove carbon deposits and deposits; \r\n 2。 Keep the fuel injector (or carburetor), intake valve and oil circuit clean, and produce less deposits in the combustion chamber; \r\n 3。 Tested by the environmental protection department, the tail gas emission can be obviously reduced, and HC and CO can be reduced by about 50%. It is an environmental protection product to reduce automobile emission pollution and improve the atmospheric environment. \r\n 4。 Fuel saving, with an average fuel saving of 2%-5%; \r\n 5。 Make the car easy to start at low temperature, speed up quickly, idle smoothly and have strong power; \r\n6。 It has excellent antirust performance and demulsification performance, and can prevent engine parts from corrosion and oil-water emulsification. \r\n7。 It has the functions of engine lubrication protection, oxidation resistance, rust prevention and noise reduction. Long-term use can prolong the life of the engine and has practical maintenance effect on the engine. \r\nUsage: \r\n 1, mixed with fuel and added to the fuel tank. \r\n2, the ratio is 1: 1000. A bottle of 65ML Hailong fuel treasure can mix 50-65 liters of fuel. \r\n3, five times is a cleaning cycle. The first five times must be used continuously, and the effect will be remarkable. \r\n4, new cars and vehicles with 20,000-50,000 km need to increase 1 cleaning cycle continuously, and vehicles with 50,000-65,438+10,000 km need to increase 2 cleaning cycles continuously. In the future, a gasoline vehicle will be added every 1000 km.
Question 8: Is the car refueling treasure useful? I majored in automobile engineering. I tell you responsibly that fuel treasure is not helpful to the engine, and some fuel treasure may even damage the engine. Fuel treasure is just a cover. He can't save fuel or clean the carbon in the cylinder. The normal EFI engine burns very cleanly and there is no organic carbon in the cylinder. Carbon deposition is caused by two reasons. 1 EFI system failure, too rich mixture and insufficient combustion. Poor quality oil will lead to. Carbon deposits usually adhere to spark plugs and cylinder heads. If you are not at ease, you can unscrew the spark plug and have a look.
Let me tell you something. Fuel treasure will spend money to buy oil and increase pollutant emissions. If you add fuel treasure to the annual inspection, I can guarantee that your car's exhaust emissions will not pass.
Regular maintenance is the most important thing.
Question 9: Does fuel treasure really work? 1-On September 20th, the engine bench report of china environmental science Research Institute showed that, according to the test method of national standard GB/T 19230, the carbon on the surface area of automobile engine intake valve can be reduced by 98% after using fuel treasure. According to the test methods of national standards GB/T 18297 and GB 18285, the engine bench report of China Automobile Technology and Research Center shows that after using fuel treasure, the maximum net power and maximum net torque of automobile engine are increased by 2%, the carbon monoxide in automobile harmful emissions is reduced by 40%, the hydrocarbon is reduced by 30%, and the fuel saving rate of automobile engine is 2%. This shows that fuel treasure can greatly reduce the carbon deposition in the engine, improve the power of the automobile, reduce the emission of harmful substances in the automobile exhaust, and improve the fuel economy of the automobile engine.
Therefore, the main functions of fuel treasure are: on the one hand, it plays a role in protecting and saving fuel for vehicle engines; On the other hand, the use of fuel detergent will reduce the particulate matter emitted by tail gas and help improve urban air quality.
However, due to the particularity of fuel treasure products, there are many fake and shoddy products on the market, so you must be careful when choosing products! Be sure to buy through formal channels.
Personally recommend China Petrochemical Hailong fuel treasure, a state-owned enterprise and a big brand, which is guaranteed.
Zhu Zongmin, producer of Hailong fuel treasure and general manager of Tianjin Yuetai Petrochemical Technology Co., Ltd. of China Petrochemical Company, said that fuel treasure is a product with independent intellectual property rights of China Petrochemical Company, and its function is to remove carbon deposits from automobile engines and maintain automobile engines. The implementation standard of Hailong fuel treasure is higher than the national standard, and the product quality belongs to the international advanced level.
Director of Fuel and Lubricating Oil Branch of China Automotive Engineering Society often introduced that China Petrochemical "fuel treasure" is composed of various effective ingredients such as cleaning agents and rust inhibitors; However, some fake "fuel treasure" with unknown composition or without antirust agent will cause engine corrosion after use. Once corrosion occurs, the whole engine and air intake system will have serious problems.
Question 10: Does fuel treasure have to be added to gasoline? Technician's suggestion: maintenance and good driving habits can really save fuel.
How big is the effect of fuel additives on cars? Wei Zengqiu, technical director of Zhengzhou Nissan Nanning Qijian Service Station, said that fuel additives can alleviate some problems such as carbon deposition of vehicles with long service life, but they can improve the comprehensive performance of vehicles and save fuel, and the effect is not obvious.
"Fuel should be added according to the vehicle's own situation, and the amount added should not be too large. General vehicles don't need or don't need to add much, because there is already an additive in the oil added by the gas station, and there is no need to add it separately. " Wei Zengqiu said that fuel additives are like nutritional drugs, which can only protect health and cannot cure diseases. After adding additives to the car, there should be no harm, but it will not effectively improve the overall performance of the car.
"Additives are nothing more than making fuel burn more fully, removing carbon deposits in cylinders and saving fuel. Such a high standard of fuel is already very clean and environmentally friendly, and additives are more of a' psychological effect'. " Wei Zengqiu said that at present, there is no authoritative and accurate test and statistical data on whether fuel additives can save fuel and how much fuel can be saved. Therefore, the fuel-saving data promoted by some products are not reliable. Theoretically, the fuel additive can decompose the carbon deposit or colloid produced by gasoline combustion on the fuel injector and intake valve, so that the gasoline can be fully atomized and burned, thus achieving the purpose of saving fuel. But in fact, it is difficult to measure how much fuel additives can save and how much power can be improved. Vehicle condition, vehicle performance and driving technology are closely related to vehicle fuel consumption. Car owners usually pay attention to car maintenance and develop good driving habits to really save fuel.
