The Limitations of Biocides in Diesel Fuel
One significant drawback of biocides is their inability to remove solid contaminants from the fuel itself. While biocides can effectively eliminate microbes and prevent future microbial growth, they leave behind dead organic matter and sludge that frequently clog fuel filters.
Frequent filter clogging increases maintenance and operational costs in addition to unplanned downtime events.

Another shortcoming of biocides is the fact that they do not address the root cause of microbial contamination and must be frequently used to prevent future microbial outbreaks.
When there's a biofilm or sludge present in the fuel, one can conclude there is likely microbial contamination. When there's microbial contamination, one can also infer there must be a significant amount of water in the fuel.
The mere presence of water creates the perfect conditions for microbial proliferation in addition to a series of other issues that can threaten the integrity of the fuel tank, fuel filters, and fuel injectors.
Biocides cannot remove water from the fuel tank thus leaving users vulnerable to the negative effects of water contamination in addition to the ideal conditions for future microbial outbreaks.
The Risk of Microbial Resistance to Biocides
The frequent use of biocides in a fuel tank may encourage surviving microorganisms to develop a resistance to the biocides being use.
