BioDiesel is a clean burning alternative fuel produced from domestic, renewable resources. BioDiesel contains no petroleum, but it can be blended at any level with petroleum diesel to create a BioDiesel blend. It can be used in compression ignition (diesel) engines with no major modifications.

BioDiesel is the only alternative fuel to have fully completed the health effects testing of the clean air act. The use of BioDiesel in conventional diesel engines has resulted in substantial reduction of unburned hydrocarbons, carbon monoxide, and particulate matter compared to the emissions from diesel fuel. In addition, the exhaust emissions of sulfur oxides and sulfates (major components in acid rain) from BioDiesel are essentially eliminated compared to conventional diesel fuel.

Do I need special storage facilities?
No. BioDiesel can be stored in your existing storage and saddle tanks. BioDiesel is completely compatible with conventional petroleum products as well as all storage solutions.

Get more mileage out of your dollars.
Although the transition to Ultra Low Sulfur Diesel has proven effective in substantially lowering emissions, the reformulated product with reduced sulfur encourages wear due to the lack of natural lubricity. BioDiesel has much higher lubricating properties than today’s conventional Ultra Low Sulfur Diesel which will help your equipment last longer and in many cases run more efficiently.

Green is Clean
Not only is BioDiesel clean burning for the environment but it's properties naturally act as a solvent keeping your tank and equipment cleaner, running smoother, extending engine life, and burning more efficient.

East River Energy offers the following BioDiesel options in blends from 1% to 100%:
• #1 BioDiesel
• #2 BioDiesel
• Biokerosene
