one of the biggest advantages Ive seen fuel adatives talk about is the cleaning of the actual injector itself. Parafin and other junk will build up in the screen/fuel rail/ fuel nozzle and cause change of flow and atomization. There is also a lot of talk of the additives being able to clean the deposits that form on the piston face as well.
