Review on Restore Your Diesel Engine Performance With Archoil AR6400-D Fuel System Cleaner by David Lambert

I had been having check engine light issues with my 2011 Super Duty (71K miles) for several months Took it the local Ford dealership and came away $850 poorer AND another check engine light before I got home. Took it back to the dealership and was told I needed a new turbo which would cost about $4000. At that time it had an engine code of P132B that couldn't be cleared. Put in a full bottle of AR3400-D and filled tank and took a 200 mile drive. The engine code cleared itself by the end of the drive. I'm a believer and just ordered the 'Real Deal' kit directly from Archoil.
