What is Bio-blended ULSD?

Ultra-low-sulfur diesel (ULSD) is very stable and relatively inexpensive. Bio-diesel is clean burning and a natural lubricant. When combined together they protect engine parts and lower the health risks associated with diesel fuel.

Government standards are changing.

Bio-blended ULSD is such a promising mixture that governments around the world (including the United States, Canada and Europe) have mandated its use for all applications. And the concentration of biodiesel in bio-blended ULSD is expected to increase to 20% in the coming years.

Bio-blended ULSD (The perfect combination?)

Bio-blended ULSD would be the perfect solution if it was not for one thing — water. The bond between the emulsified water and the fuel is so strong in this mixture, that existing filters cannot separate them adequately. And even small amounts of water in diesel fuel can lead to big problems.

The NFPA. And the EPA.

The National Fire Protection Agency (NFPA) was so concerned about water contamination in diesel fuel that they investigated it. In their “NFPA 110 Standard for Emergency and Standby Power Systems” they explain that the addition of biodiesel accelerates the degradation of diesel fuel. The US Environmental Protection Agency (EPA) agrees with their findings.

The NFPA currently mandates that diesel fuel be discarded and replaced every year and that bio-blended ULSD be changed every 6 months.

• ULSD diesel = must be completely replaced every year
• ULSD blended bio-diesel = must be completely replaced every 6 months.

These strict guidelines must be followed to ensure public safety. The NFPA allows for only one exception — using an SAE J1488 ver. 2010 rated filtration system to keep the fuel within ASTM specification. (To pass the SAE J1488, the filter must exceed the minimum 92% efficiency on that fuel type to ensure continuous fuel stability.)
DieselPure is an alternative to discarding fuel as outlined by the NFPA. It removes all types of water including emulsified water. It exceeds the efficiency requirements of the current SAE J1488 version, and ensures that your emergency backup fuel is ready when you need it most — in an emergency.
