Frequently Asked Questions
What should I do during cold weather?
Pure biodiesel (B100) will gel in cold weather. When the temperature is above freezing, 32°F, you can generally run B100. When the temperature drops below freezing, you should do one or more of the following: use a biodiesel flow improver; physically warm the fuel using tank, fuel line and/or filter beaters, or park your vehicle in a warm place at night; blend with #1 and/or #2 petro-diesel. Generally a blend of 50/50 biodiesel and #1 petro-diesel will flow down to 0°F. A blend of 50/50 biodiesel and #2 petro-diesel with the correct anti-get will also flow down to 0°F.
Several factors can have an influence on the cloud, cold filter plugging point (CFPP) and gel point of your biodiesel, as well as the flow in your vehicle. These factors include: saturation level and type of the veggie oil the biodiesel was made from, whether anti-gel was added to the biodiesel and/other petro-diesel mix, size of fuel lines, amount of work fuel returned by your vehicle to the fuel tank, size and placement of fuel filter on your vehicle, whether your vehicle has a fuel pre-heater, etc.
It is better to be safe than sorry concerning gelling and use extra petro-diesel in the blend. A B20 blend will generally gel at a very similar rate as the petro-diesel it is blended with, including any anti-gel agent.
Many people “winterize” their biodiesel by placing a drum of it outside during cold temperatures and then drawing off the top of the drum. The lighter weight “winter” biodiesel will be on top while the heaver “summer” biodiesel goes to the bottom of the drum.
We recommend Power Service brand biodiesel anti-gel additives when blending petro-diesel with biodiesel. We also recommend Artic Fox brand products if you decide to heat your vehicles fuel system. Please call or email if you have additional questions concerning cold weather use and
