What about Sopamil fuel treasure?

As far as my own practical experience is concerned, I really think this fuel treasure is good for some cars that love carbon deposition, and it still has a strong effect in treating idling jitter.

Fuel treasure is a popular name, and fuel treasure is a gasoline additive, which can effectively reduce the "knock" phenomenon of gasoline engines. Most fuel treasure in the market can be divided into two types: increasing octane number and cleaning up carbon deposits. Cleaning the fuel treasure can clean the carbon deposit on the throttle and intake valve, thus reducing fuel consumption and engine jitter. The carbon removal rate of Sopamil fuel treasure is as high as 97.4%. Using imported pea stock solution can not only remove the carbon deposit in the engine, but also improve the power, save fuel consumption and clean the oil circuit. It is a "panacea" for vehicles.
