Biodiesel is a term for renewable, non-petroleum-based, biodegradable, cleaner-burning fuel that can be manufactured domestically from vegetable oils, animal fats or recycled restaurant grease. The use of Biodiesel helps reduce reliance on foreign imported oil, while supporting American farmers and domestic job creation.
Biodiesel is a liquid fuel often referred to as “B100” or “neat biodiesel” in its pure, unblended form. Like petroleum diesel, biodiesel is used to fuel compression-ignition engines, which run on petroleum diesel.
Biodiesel meets both the biomass-based diesel and overall advanced biofuel requirement of the Renewable Fuel Standard. The Renewable Fuel Standard (RFS) is a federal program that requires transportation fuel sold in the United States to contain a minimum volume of renewable fuels.
Biodiesel performance in cold weather depends on the blend of biodiesel, the feedstock, and the petroleum diesel characteristics. In general, blends with smaller percentages of biodiesel perform better in cold temperatures. Typically, No. 2 diesel and B5 (up to 5% biodiesel) perform about the same in cold weather. Both biodiesel and No. 2 diesel have some compounds that crystallize in very cold temperatures. In winter weather, fuel blenders and suppliers combat crystallization by adding a cold flow improver. For the best cold weather performance, users should work with their fuel provider to ensure the blend is appropriate.
As of 2024 there are 23 Biodiesel dispensing stations in Wisconsin selling B20 and above. You can find a real time map of their Geo-locations here.

National Biodiesel Board
The National Biodiesel Board is the national trade association representing America’s first advanced biofuel. The organization works to create sustainable biodiesel industry growth through education, communication, governmental affairs, technical and quality assurance programs. Serving as the coordinating body for research and development in the U.S., the National Biodiesel Board is comprised of state, national and international feedstock processor organizations, biodiesel suppliers, fuel marketers and distributors and technology providers.
