What are the methods for removing carbon deposits from cars?

[LaArthur]

Methods for removing carbon deposits from cars are as follows: 1. For mild carbon deposits: Simply add fuel additives. The oil-repellent molecules in fuel additives can lubricate the fuel system, making fuel injection smoother. 2. For severe carbon deposits: Clean components such as the throttle body and intake manifold. Generally, this involves removing the engine cover, taking off the throttle body, spraying it and the intake manifold with carburetor cleaner, and then wiping them clean. 3. Methods to prevent carbon deposits: Use clean fuel that meets the specified octane rating. You can add cleaning-type fuel additives when refueling, but make sure to choose reputable brands. Develop good driving habits, such as shifting gears in manual transmissions above 2000 RPM. Regularly drive at high speeds to allow the engine to run at high RPM and clear minor carbon deposits on its own. Avoid prolonged idling.
