Penray Fuel Prep™ Biocide Solves Diesel Fuel Storage Problems

Powerful fungus and bacteria-killer ideal for diesel fuel storage at fuel wholesalers, trucking and construction companies, marinas, farms…

Wheeling, IL June 15, 2015 – The Penray Companies, Inc. is now offering its Fuel Prep™ Biocide for use in diesel fuel storage tanks. This product kills off microbial growth in diesel fuel, which is a problem when water accumulates in diesel fuel storage and transport tanks. It is important to address the growth of these contaminants before the fuel is pumped into trucks, construction equipment, boats, and other diesel-powered vehicles.

The Penray biocide is a fast-acting, single-dose biocide that stops 90% of microbial growth activity in as little as six hours. It is so effective you may only have to treat twice a year. By doing so, it can protect all components of the fuel storage system from the corrosion that microbial growth can cause. At the same time, it prevents the formation of microbial growth (bugs) that can plug fuel filters, interfering with fueling efficiency, and causing expensive downtime. Penray’s biocide is conveniently packaged in pints or gallons, to treat 1,250 or 10,000 gallons respectively.

Penray’s Fuel Prep Biocide is effective in all types of diesel fuels, including ULSD and the various blends of biofuels. This is particularly important during the warm summer months, when moisture and the micro-organisms (bugs) that naturally occur in water thrive and grow in fuel tanks. The bugs feed off the hydrocarbons in fuel, and can double their growth in population every 20 minutes. Ultimately, the bugs’ waste products produce sludge, acids and other harmful by-products. Over time these can turn into black, brown or green slime, which ultimately clogs vehicle fuel filters, fuel lines, injectors, and other fuel system components. This greatly affects vehicle performance and certainly adds to the expense and downtime associated with the resulting necessary repairs. So it’s far better to treat the fuel in bulk storage in order to prevent vehicular problems later.

Specific benefits of this product include:

  •  Elimination of system-clogging microbial growth.
  •  Reducing tank corrosion.
  •  Reducing slime and foul odors.
  •  Preventing premature hose/gasket wear or failure.
  •  Reducing downtime and saving repair costs.

Since vehicles may often re-fuel at various locations with unknown tank maintenance practices, Penray also offers diesel fuel additives for use in individual vehicle tanks. Penray recommends year-round fuel treatment for individual vehicles and twice-yearly fuel testing of storage tanks via the Penray Fuel Doctor Program. In addition, the company recently introduced POW-R 365™ 5 in 1 Diesel Cleaner & Treatment, a year-round additive that cleans injectors to improve fuel economy, enhances lubricity to prevent wear, prevents corrosion protecting engine components, lifts cetane for improved starts, and reduces CFFP to prevent gelling in cold climates.

Explains Penray’s William Nonnamaker, Senior Vice President of Sales, “Penray has long been known for additives, supplements, and functional fluids for heavy duty diesel-powered vehicles. We work closely with fleet maintenance supervisors and other key players in monitoring needs and problems that develop with changes in the industry, including new fuel blends. We further help provide education to our customers on the need to test and treat fuel year-round. The new addition of the Fuel Prep Biocide to our existing fuel treatment line and Fuel Doctor Program is part of our on-going commitment to keeping heavy-duty vehicles moving and productive.”
