Fuel quality articles and practical insights
Original guidance for operators managing stored petrol and diesel, fuel contamination, water, microbial risk and equipment reliability. Start with the operating problem, then follow the relevant technical and product information.
Investigate the issue, not just the symptom
A blocked filter, cloudy sample or unreliable engine start can have several causes. These articles help operators distinguish physical contamination, water, microbial activity and fuel ageing before selecting a response. Articles are educational and do not replace a representative sample, laboratory analysis where warranted or equipment-specific instructions.
Water in diesel fuel
Recognise free and emulsified water, why the distinction matters and when draining or further investigation is required.
Microbial growth in stored diesel
Understand the relationship between water, microbial contamination, tank condition and appropriate testing.
Fuel sampling and testing
Understand representative sampling, sample locations and the limits of individual field tests.
Blocked diesel filters
Explore why filters restrict and why a blockage alone does not identify the underlying contamination.
Fuel polishing versus treatment
Compare physical cleaning and filtration with chemical fuel treatment, and learn where each fits.
Diesel oxidation and stability
Review how stored fuel can change over time and why storage conditions and turnover matter.
Application-specific reading
Different equipment, storage durations and duty cycles create different fuel-quality risks. Use these articles alongside the relevant maintenance instructions and site operating procedures.
Backup generator fuel maintenance
Plan practical condition checks for low-turnover, critical standby fuel systems.
Marine diesel contamination
Investigate water, sludge and filter risk in marine diesel tanks.
Boat petrol, E10 and phase separation
Understand marine petrol storage, ethanol-blend compatibility and why suspected phase separation requires specialist assessment.
Yacht and boat fuel maintenance
Prepare a practical fuel-quality programme for infrequently used vessels.
From investigation to a fuel-quality plan
Test
Use appropriate sampling and FUELSTAT microbial testing when microbial contamination is suspected. A single field test does not assess every fuel property.
Manage water
Address free water, water ingress and tank condition. Review Aquafighter for suitable stationary diesel-tank applications.
Treat and maintain
Review the Fuel Right treatment range against the specific fuel and application; continue condition checks rather than assuming any additive replaces cleaning.
