Avoid Cloudy Fuel this Winter at Your Truckstop

When properly managed, high-quality biodiesel blended fuels are successful in the coldest of climates. Blends of 5 percent and below have virtually no impact on cold weather operability. But, just like No. 2 petroleum diesel, biodiesel can gel in very cold temperatures.

So, it is important to understand the cold flow properties of both petroleum diesel and biodiesel when blending fuel for winter use. Biodiesel producers conduct tests to ensure each gallon produced meets or exceeds industry ASTM standards. The results are listed on the Certificate of Analysis (COA) that is provided with each shipment of biodiesel.

Among the specs listed is cloud point. The cloud point is described as a conservative temperature for the point at which biodiesel will begin to freeze ― not solidify, but begin to become cloudy.

Renewable Energy Group, Inc. recommends that our customers store biodiesel at 10 degrees above the cloud point. Underground tanks will typically remain in the 50 degree Fahrenheit range through the winter months, while above ground tanks may need to be heated or insulated just to be safe.

The blend percentage should also be considered when examining cloud points. Traditional diesel fuel has a lower cloud point than biodiesel; thus, when blending at a B5 level, the cloud point of the blended fuel will be reflective of the diesel and biodiesel mixture.
