And its also a ford....I've used this before on a old Ford 4.2... and those engines had a track record for deposits. Based on our DI, I don't see any other product like this that would work to decarbonize. Any of the 'add to the tank' additives wouldn't remove any deposits at the valves.
I will say, while the 4.2 did blow smoke during the cleaning process there was no noticable improvement in the performance of the engine. It was at ~190k miles and tended to have a lot of detonation, regardless of octane rating used.
