FPPF Chemical Company has been producing diesel fuel treatments and additives for over 40 years. Their lineup includes anti-gel formulas, fuel biocides, injector cleaners, and lubricity enhancers formulated for ULSD fuels used in modern Peterbilt diesel engines. FPPF products are particularly well-regarded for cold-weather protection, helping prevent fuel gelling and filter plugging during winter operation — a critical concern for long-haul drivers running in northern climates.
