AFC is the best fuel additive available, working to improve your engines performance and increase overall reliability.


The AFC fuel additive line is built upon a unique and powerful broad-spectrum fuel catalyst formulated for hydrocarbon-based fuels (i.g. diesel, bio-fuels, gasoline, kerosene, and heavy fuel oil). This fuel catalyst effectively decontaminates and cleans the engine’s fuel system of carbon deposit buildup while improving overall performance through enhanced combustion. Outside the engine, all AFC fuel additive formulas work in the storage tank by stabilizing the fuel for up to 12 months with a single dose. AFC fuel additives prevent corrosion and reduce engine component wear through the addition of a corrosion inhibitor and lubricity enhancer. All AFC variants are designed for continual use as part of any preventative fuel maintenance program with specialized formulas for specific needs.

AFC-705 adds a dispersant and surfactant to its formula to help breakdown contaminants and inhibit microbial growth in the fuel tank. AFC-710 and 805 are rated for Tier-4 engines by removing the surfactant ingredient to prevent water from damaging the low tolerance High Pressure Common Rail (HPCR) injector tips. AFC-710 Powder creates an alternative to the AFC-710 liquid offering by providing users with a lighter, more compact, form of the Tier-4 compliant formula. AFC-805 is a winter blend of the AFC-710 with an added agent to prevent gelling of the fuel in cold temperatures.

All AFC fuel are EPA registered for on-road and off-road use and will work with other fuel additives. For a full breakdown comparison of each AFC fuel additive consult the chart below:
