Diesel bug is not something you want to experience.
This brown/black slime looks rather like frogspawn and has a pungent, eggy odour. It can grow in diesel fuel tanks where water is also present due to wet conditions or air entering the tank and causing condensation. Before long, it will block your fuel filters.
The answer is to treat your fuel with Exocet Anti Bug Kill – 1-litre will treat 5,000 litres of fuel. Within 24-36 hours it will kill microbiological infestations, eliminating plugging of filters and gauges and maintaining combustion and emission quality.
Exocet Anti Bug Kill is in stock at all T H WHITE Agricultural parts stores at £46.50 + VAT.
