[ParkerLee]

Methods for cleaning carbon deposits in a car: 1. Remove the engine cover, take off the throttle valve, clean it with carburetor cleaner, dry it with a cotton cloth, and then reinstall it; 2. Open the oil cap, pour in the entire can of cleaner, close the oil cap, start the engine and let it idle for ten minutes before turning it off; 3. Pour the intake system cleaner into the liquid storage tank of a dedicated cleaning device, connect it to the intake system, and start the engine to use vacuum to draw the cleaner into the intake tract for cleaning. Methods to identify carbon deposits in a car: 1. Check the fuel consumption; if the increase continues to rise, it indicates that carbon deposits have formed on the engine; 2. Based on the mileage, the higher the car's mileage, the more carbon deposits will accumulate; 3. Replace with higher-grade gasoline; if there is an improvement in power, it means there is more carbon deposit in the engine.
