How many kilometers does the engine usually do hydrogen and oxygen decarbonization?

First of all, there are three kinds of engine decarbonization cleaning. First, the carburetor cleaning throttle can wash away a small amount of carbon deposits in the engine. Second, water-based foam cleaning is more troublesome and not enough. Third, engine overhaul, not to mention "surgery" is very harmful to the start. You won't spend a lot of money on an engine overhaul because of carbon deposition and high fuel consumption! At most, the repair shop suggests that you wash the throttle or something and answer "two"

Finally, it belongs to the hydrogen and oxygen decarbonization machine. I suggest that you can find a guaranteed shop or repair shop. Having this instrument may bring you different surprises.
