Biodiesel is a very simple and cost effective alternative to diesel fuel. With the increase of goods shipped and retail sales in 2018, trucking companies are looking for an alternative to costly and environmentally hazardous diesel fuel. With a 111% increase in biodiesel usage between 2012 and 2018, more fleets are looking to invest in a fuel that is 80% petroleum diesel and 20% biodiesel. Biodiesel is cheaper, is easier on fuel filters, and lowers greenhouse gas emissions.
