Left untreated, fuels are susceptible to bacterial and fungal contamination that can cause machine malfunction, filter clogging, and microbial induced corrosion. Fuel biocides are critical for maintaining fuel integrity during storage, distribution and use.


Microbial Control’s portfolio of fuel treatment solutions effectively fights bacteria and fungi –from rapid decontamination of spoiled fuel to shock treatment of heavily fouled systems and preventative maintenance treatments for clean fuel. Our effective fuel preservatives enable compliance with permissible sulfur level standards and help you protect your valuable investment. Some of the applications where our products can be used are:

  • For general use in storage tanks, fuel tanks to control microbial growth in diesel oil, fuel oil or gasoline
  • For storage above water in bulk storage systems
  • For storage without intentional water
  • For addition to fuel pre-mixed with other fuel additive
  • Oil and gas water storage and transmission systems
