Fuelstat is an on-site field test that detects microbial contamination in marine diesel fuels in 15-30 minutes: no lab required, no specialist equipment needed.
The test identifies bacteria, fungi, and yeast contaminants that cause filter blockages, injector damage, and tank corrosion. Test your fuel in port or at sea and get immediate verification of contamination levels, preventing engine damage and costly downtime by catching problems before they escalate.

How it works
Fuelstat uses protein-ligand complex detection technology to identify a broad range of microbial contamination in fuel. Results are read via the free app, which provides both a contamination level (Negligible/Moderate/Heavy) and a fully quantitative result value, giving you both instant assessment and detailed data for your records.
Digital reporting
The free Fuelstat Result app (iOS and Android) verifies your results instantly and sends reports via SMS or email. All test data uploads to a secure cloud portal, giving you access to historical records from anywhere – useful for tracking fuel quality across your fleet and maintaining compliance documentation.
