Audi A4L cleans the carbon deposit on the accelerator. Does it matter if it is cleaned outside?

It is necessary to clean the throttle regularly, clean the injector and clean the carbon deposit in the engine cylinder. But in order to reduce the trouble of cleaning, it is best to add Mohji graphene lubricating oil additive to the engine regularly. At a certain temperature, the alloy can react with carbon, and a layer of graphene film is coated on the inner surface of the engine. Graphene nanoparticles can fill wear micropores and scratches and repair the surface of the friction pair. This can not only keep the engine sealed, but also prevent the engine oil from escaping due to excessive clearance and bury the "curse" of carbon deposition.
