Product Guide

There are three main types of Gumout^® performance additives: complete fuel system cleaners, fuel injector cleaners and gas additives. Complete fuel system cleaners are formulated to remove carbon deposits and prevent future buildup across the fuel system, including difficult to clean parts like GDI/direct injectors and piston tops. Many also include conditioning benefits, like friction reduction and protection against ethanol corrosion. Fuel injector cleaners, on the other hand, focus specifically on port/indirect injectors, intake valves and ports, while gas additives focus on improving gas quality. To find the right product for your vehicle, explore each of the categories below.
