These are the fuel treatments I trust. Berryman's will dissolve nearly anything in the tank, fuel lines, or injectors (and it's also very effective in the crankcase), and Techron has consistently been among the best fuel treatments available. I also add Marvel Mystery Oil (MMO) to modern gasahol, and in the crankcase, to prevent valve stick and lifter clatter.
