Is cold weather a problem for higher blends?
Yes. The B99.9 will begin to gel around freezing (between 32-36° F) and will clog fuel filters between 22-28° F. Gelled fuel melts when warmed. Fuel rarely gels while the engine running and circulating fuel through the system. Cold morning start-ups are generally the only time that gelling becomes an issue. There are three important actions you can take to continue using biodiesel in temperatures below freezing: add heat, add petroleum, or add a winterizing additive. The easiest cold weather solutions for western NC seems to be a B60 blend (60% biodiesel/40% petro-diesel) or B70 with an anti-gel in the fuel. Blue Ridge Biofuels ONLY sells “winterized” fuel during the winter months that is appropriate for the climate in western North Carolina. This means we take care of gelling for you!
