For many vessels, adding a biocide has simply become part of the fuel-management routine. Fuel comes onboard, biocide is added, and the process is repeated at the next bunker.
But if you don’t have confirmed microbial contamination, why are you routinely using a biocide?
V25 offers a different approach. As a non-biocide diesel fuel treatment, V25 doesn’t chemically kill microorganisms. Instead, it physically conditions the fuel, helping manage the conditions associated with microbial contamination while providing wider benefits throughout the fuel system.
A Non Biocide Diesel Fuel Treatment
Water plays an important role in microbial contamination because microorganisms require water to remain active within a diesel fuel system.
V25’s physical fuel-conditioning action helps separate water and disperse agglomerations and deposits, supporting their removal through normal drainage, filtration and separation.
Rather than routinely trying to kill microorganisms, V25 helps manage the fuel environment and the conditions associated with diesel bug.
What Else Is Your Treatment Doing?
Diesel bug isn’t the only challenge your fuel system faces.
V25 helps support:
- Fuel stability
- Water management
- Dispersion of contamination and deposits
- Improved lubricity
- Pumps and injection equipment
- Injector cleanliness
- Improved atomisation and combustion
- Reduced smoke and particulates
Instead of focusing on one potential problem, V25 provides fuel-management benefits from tank to funnel.

Designed for Routine Use
If you’re adding something at every bunker, its handling and storage characteristics matter.
V25 is non-hazardous, vegetal-derived, ashless and metal-free. It’s highly concentrated too, with a standard dosage of just 1 litre per 10,000 litres of fuel.
That makes it straightforward to incorporate into regular bunkering and refuelling routines.
Is It Time to Rethink Routine Biocide Use?
If significant microbial contamination has already been confirmed, it should be properly assessed and may require remedial action. V25 isn’t a direct replacement for every remedial use of a biocide because it doesn’t kill microorganisms.
But if you’re routinely dosing biocide simply as a preventative measure, V25 offers a different approach.
As a diesel fuel biocide alternative for ongoing fuel management, V25 helps manage water and contamination while supporting stability, lubricity, cleaner fuel systems and more complete combustion.
Don’t just treat one problem. Manage your fuel from tank to funnel.
