Schulke Grotamar 82 Biocide

Preservative for modern B5* - B100* diesel fuel and heating oil.

Whether “diesel bug”, “fungus”, “bacteria” or “MBC” – infestation by microorganisms in diesel fuel has many names.

Whatever you call the phenomenon, it has a common cause. Free water in the diesel will enable the growth of bacteria, yeasts and moulds. Small amounts of water which form by condensation are sufficient to stimulate microbial growth in a fuel tank.

Today, “fossil” diesels are blended with environmentally friendly biodiesel. Biodiesel is good for the environment but also good for microbes. Biodiesels are a good source of nutrition for microbes and they promote the contamination of the fuel with water. Biodiesel is also less stable than “fossil” diesel and degrades with ageing leading to darkening and formation of solid deposits.

Microbes grow faster than ever, forming “biomass” and causing corrosion. The “biomass” clogs filters and leads to engine failure. This places the operating reliability and safety of the whole system at risk!
