Can biodiesel be blended with No. 2 Diesel?
Yes and at any level. Some use biodiesel as a fuel additive to increase lubricity and some use biodiesel as their main source of transportation fuel. A common blend around Texas and other states is 20% biodiesel mixed with 80% petrol diesel also known as B20. Biodiesel has a high cloud point and in the winter it is necessary to blend biodiesel or use an additive to reduce and minimize crystals that form.
