This is my first GDI vehicle but I have heard of this problem in the past about these engines. From my reading the common consensus....you do not want to use these types of products due to exactly what @t4thfavor stated above. Ford does not approve of their use and the only thing I have seen that is approved is a replacement or walnut blasting. From the vids and articles I was reading on the topic....if it was under warranty Ford was telling technicians to just replace during extreme buildup/power loss.
