Can the fuel cleaning agent for automobiles really remove carbon deposits in automobiles? If so, how much is a bottle? Thank you very much

Carbon deposits in the fuel system can be removed by cleaning agent. Aowei carbon deposit cleaning agent is the best, safest and most convenient, and the first commitment is invalid, with technical support and after-sales service. A bottle can clean the carbon deposit on the fuel tank, fuel pipe, fuel nozzle, air intake, air intake valve, combustion chamber and piston ring, which can effectively solve the problems of engine trembling, difficult cold start, poor drive acceleration, increased fuel consumption and oil consumption caused by carbon deposit. A bottle is about 180.
