ULTRABURN is a clean-burning formulated biodiesel fuel made from Kentucky grown soybeans.
ULTRABURN Basics
ULTRABURN is a clean-burning formulated biodiesel fuel made from Kentucky grown soybeans. The term biodiesel refers to pure, unblended fuel that meets ASTM D6751 standards and specifications. Our ULTRABURN F20 is blended with 20 percent CRC produced biodiesel, 80 percent petroleum diesel and special additives are added to the blend to increase lifespan and performance of the fuel.
ULTRABURN is compatible with most diesel vehicles and equipment. Several engine manufacturers approve F20 use so long as the biodiesel meets the fuel quality specification ASTM D 6751. Some manufacturers approve even higher blends.

Cetane Number is a measure of the ignition delay (the time from fuel injection into the combustion chamber to ignition) higher cetane numbers are believed to provide easier starting and quieter operation.

Industries We Serve
COAL MINING

ULTRABURN has many advantages over petroleum diesel for people who live and work aboveground, but it is even more beneficial for those working underground. Because it produces less particulates when it burns, ULTRABURN protects miners and helps mine operators meet air-quality standards.
MARINE

ULTRABURN fuel in the marine sector began in 1998 when a feasibility study initiated the use of soybean biodiesel for recreational boats in the Great Lakes region in North America.
AGRICULTURE

ULTRABURN is a renewable source of energy that can help reduce greenhouse gas emissions and minimize the “carbon footprint” of agriculture. It contributes less to global warming because the carbon in the fuel was removed from the air by the plant feedstock.
RETAIL

Purchasing ULTRABURN from CRC is the easiest way to quickly begin selling a biodiesel blend. CRC offers the blends from F5 to F99.
FAQs
DOES ULTRABURN F20 HAVE SIMILAR PERFORMANCE TO PETROLEUM DIESEL?
YES. Diesel vehicle drivers should see similar power and performance.
CAN I USE ULTRABURN IN MY VEHICLE?
YES. Ultraburn F20 can be used in any diesel vehicle. Most major engine companies have formally stated that use of blends up to F20 will not void their parts and workmanship warranties. Unless use of a higher-than recommended blend of biodiesel is the cause of engine or parts failure, the warranty must be honored.
DOES ULTRABURN HAVE A SIMILAR SHELF LIFE TO ULTRA-LOW SULFUR DIESEL?
YES. Our formulations of biodiesel are designed to meet or exceed the shelf life of ULSD of one year.
IS MICROBIAL CONTAMINATION RISK WITH ULTRABURN SIMILAR TO ULSD?
YES. Our Ultraburn blends are formulated to prevent microbial contamination.
CAN ULTRABURN BE USED IN WINTER?
YES. ULTRABURN can be used year-round anywhere ULSD is used. ULTRABURN Blends up to 20 percent should be treated the same as ULSD. Blends higher than 5 percent may require additives and/or the addition of No. 1 diesel, depending on the local temperature and characteristics of the base diesel fuel. We will prepare an ULTRABURN biodiesel blend based on your climate condition.
ARE THERE FUEL QUALITY STANDARDS FOR ULTRABURN?
YES. Like petroleum diesel, ULTRABURN will meet strict quality standards before it is released into the fuel distribution system.
