Using biodiesel is good for the environment but Mother Nature doesn’t always return the favor. FPPF Biodiesel Treatment prevents wax formation in your biodiesel fuel in wintry weather and harsh conditions. If left untreated, the platelets in your biodiesel stick together, plug your filters and fuel lines, and cause your engine to shut down. Biodiesel Treatment is specially formulated for all biodiesel fuels, including B-20 (typically 20% soy or vegetable oil and 80% #2 diesel fuel) and keeps these fuels flowing in temperatures as low as -40°F. FPPF recommends you be proactive with your winter fuel treatments and add Biodiesel Treatment to your fuel when the fuel temperature is at least 30°F. To get the most out of your biodiesel, treat the pro-power way with FPPF Biodiesel Treatment.
