The main component of "Chexiaojia" is methanol, and the content indicated on the package is "greater than or equal to 60%", but the actual content is far more than that. According to the inspection report issued by Yantai Product Quality Supervision and Inspection Institute, the methanol content of Che Xiaosheng reached 9 1%.
Excessive methanol content may lead to vehicle fuel system and engine failure. Automobile fuel system and engine have poor tolerance to methanol. Using a large amount of methanol will lead to corrosion, expansion, softening and cracking of synthetic rubber materials, as well as metal pitting corrosion of carburetor. Ordinary cars cannot use unmodified fuel with high methanol content.

The "core technologies" promoted by 1 and "Che Che Xiao" involve lubricants, micro-explosive agents, cleaning agents, dissolving agents and so on. There is even a "phase change catalyst" that "decomposes water into oxygen and hydrogen to continue secondary combustion", but it does not involve the protection of rubber and metal parts.
2. Experts also questioned the fuel-saving effect of "Car Whispering": the calorific value of methanol is much lower than that of gasoline, and a large amount of use will inevitably lead to a decline in power and an increase in fuel consumption. After adding methanol, gasoline burns less, but the fuel cost does not necessarily decrease.
3. The main component of "Car Whispering" is methanol, which is a dangerous chemical. If it is used according to the recommended amount, it will lead to the decline of automobile power and the corrosion and failure of vehicle fuel system, which runs counter to the publicity effect.
