Do you need to change the oil to clean up the engine carbon deposit?

You don't need to change the oil. Cleaning up the carbon deposit will not affect the oil. Take off the engine decorative cover, remove the throttle, clean it with carburetor cleaner, dry it with cotton cloth and install it. The cleaning cycle of the throttle valve is 20,000 kilometers. Before refueling, add the whole bottle of fuel additive to the fuel tank, and the cleaning cycle is 30,000 kilometers.

Preventive measures for cleaning internal carbon deposits

Open the oil cover, pour the whole tank of cleaning agent (mixed with old oil), cover the oil cover, ignite the engine at idle speed 10 minutes, and then turn off the engine. Clean the carbon deposit inside the engine. This cleaner can dissolve the deposits such as sludge, colloid, moisture and metal debris inside the engine, reduce the pollution of new engine oil and prolong the service life of the engine.

The cleaning method of engine carbon deposit is also very simple. Before maintenance, just add a bottle of engine internal cleaning agent to the oil port, idle for about 10 minutes, and then immediately maintain and replace the oil filter.
