As of 2006 the most common diesel fuel is ultra-low-sulfur diesel (ULSD). There have been many different formulations of ULSD, all of them developed to reduce sulfur and the emissions of particulate matter. Unfortunately, the process used to lower the sulfur content of ULSD also reduces its lubricating properties.
Biodiesel — and its benefits
In recent years, bio-diesel has been added to ULSD. Mixing bio-diesel with ULSD increases it’s lubricity to protect engines from excessive wear.
Another benefit of bio-blended ULSD is that bio-diesel reduces the amount of unburned hydrocarbons and carbon monoxide — compounds known to pose serious health risks. In fact bio-blended ULSD reduces some cancer-causing compounds by as much as 75-85%.
Biodiesel + ULSD = Bio-blended ULSD
- ULSD is very stable and relatively inexpensive.
- Bio-diesel is clean burning and a natural lubricant.
Combining together biodiesel and ULSD helps protect the precise internal workings of engines and lowers the health risks associated with diesel fuel. Bio-blended ULSD addresses a lot of the environmental and mechanical issues associated with diesel fuel. However, the real problem is water.
Bio-blended ULSD likes water. It is very hygroscopic — it attracts and holds water from the surrounding environment. When bio-blended ULSD absorbs water it emulsifies forming extremely strong bonds. In fact most filters cannot remove emulsified water. Yet removing all the emulsified water from diesel fuel is critical because water:
- increases wear rate + damage to fuel injectors
- accelerates microbial growth which degrades the fuel
- causes pitting of steel pipes and tanks
- allows acetic acid to form which corrodes tanks + internal engine parts
Even the smallest amount of emulsified water can cause enormous damage. Engine parts wear out much more quickly and fuel storage tanks corrode.
Emulsified water is so difficult to remove from fuel that most facilities simply dispose of it as a hazardous waste or burn it as heating oil. In fact the NFPA recommends that bio-blended ULSD be replaced every 6 months. But there is an alternative, a better solution — DieselPure.
DieselPure complies with all of the standards set out by the NFPA. It also meets the most stringent filtration test in the industry — the SAE J1488 ver. 2010. DieselPure exceeds the required efficiency rating for removing emulsified water for all types of diesel fuel.
The only proven protection against emulsified water is to use a filtration system that passes the strict requirements of SAEJ1488 ver. 2010. The filter must meet the 92% efficiency rating.
DieselPure not only meets the rigorous testing criteria of the SAE J1488, but exceeds them. And it does so with all types of ULSD including the most difficult formulation, ULSD blended bio-diesel fuel.
