If you’ve noticed more “sludge” in your filters lately, you’re not alone. The shift towards higher FAME (Fatty Acid Methyl Ester) content in modern diesel has made fuel more “hygroscopic” – meaning it pulls moisture directly from the air.
This moisture creates the perfect breeding ground for the “Diesel Bug.” Once these microbes establish a colony, they produce waste products that are acidic, leading to tank corrosion and thick, black slime that halts operations.
How to fight back:
- Extraction: Use a Dirty Fuel Extraction System to remove the water and sludge sitting at the bottom of your tank.
- Filtration: Run the remaining fuel through a polishing system to remove suspended particulates.
- Prevention: Implement a regular testing and polishing schedule to ensure the bug never gets a foothold.
