Fuel Sampling & Testing

West Fue Systems Limited

Fuel Hygiene

Road diesel & gasoil now contain a percentage of bio-fuel (up to 7%). This provides an ideal breeding ground for diesel/gasoil bugs.


Equipment failure can be down to bugs in these modern fuels. Problems with contaminated fuel inside storage tanks can cause pumps & vehicle filters to block, & in severe cases, vehicles can stop working causing downtime & hefty repair bills.


These issues are caused by microbial contamination (often known as diesel bugs which are micro-organisms that grow on water present in fuel). This problem has been known but contained for years until the age of the latest fuels.

Fuel Testing For Microbes:


Testing for microbial contamination in diesel & gasoil gives people storing fuel a warning so that they may prevent microbial contamination reaching dangerous levels. This would will cause problems to the fuel & equipment therefore testing before it happens prevents vehicle & equipment downtime & expensive repair bills.


Our test measures the total quantity of microbiological activity through a single analysis within minutes. The test report gives you a traffic light warning sequence:


Green = Low contamination, no preventive action is required < 10pg/ml

Amber = Medium contamination, preventative action is required 10 < 100pg/ml

Red = High contamination, preventive/remedial action is required > 100 pg/ml
