Marine 16 Diesel Bug Treatment (DBT) is a Biocide formulated specifically for preventing or eradicating the microbial contamination known collectively as Diesel Bug.
DBT – Diesel Bug Treatment is a broad spectrum biocide formulated to prevent or eradicate the microbial contamination of fuel from Yeast, Mould and Bacteria commonly known as Diesel Bug. A 100ml bottle is sufficient to prevent diesel bug growth in 2000 litres of fuel (50ppm). For serious contamination this should be increased to 100ml to 100 litres (1000ppm). Our diesel bug treatment disperses into both the water and fuel phases in your tank and will remain sufficiently active for over a year at both high and low temperatures. Marine 16’s Diesel Bug Treatment is the fuel treatment of choice for the RNLI, The Royal Marines, Sea Start and River Canal Rescue as well as being number 1 in the Practical Boat Owner magazine review.
Overdosing will not harm your engine.
Note: Diesel Bug exists because there is water, it is essential to drain the water out of the tank regularly, at least once per month.
