Ok... So a question for you guys. In the last few months one of the Ford Tech Malculco (?sp) videos has a section where he relates a a conversation with Ford engineers on the Ecoboost GDI turbo engines in which he relates that they told him that Ford doesn't recommend in tank engine cleaner additives (those beyond the ones already in a fuel blend) because of accelerated turbo failure. Any comments or info/data?
