How would using a gasoline additive help to clean the carbon from the valves.
My limited understanding of GDI engines is that the carbon accumulates on the valves because the gas is directly injected into the cylinder, not the airways and so the valves don't get washed by an air fuel mixture.
Seems like a gasoline additive would only clean the injectors in a GDI.
Thanks for the education.
