How Healthy Is Your Fuel?

Even when fuel meets “spec” at delivery, it can degrade as it moves through distribution and storage systems. Over time, water, microbial growth, sludge, and particulates can quietly build up, causing:

Fuel Filter Plugging & Injector Fouling

Increased Regens

Decreased Performance & Reliability

Increased Maintenance & Repair Costs

Tank Rust & Corrosion

Without regular testing, these problems often go unnoticed until it’s too late. Assess your fuel's health by scheduling a FREE Certified Fuel Quality Checkup™.

1. Analyze

Regular testing helps detect fuel issues before they become major problems. We start with a comprehensive evaluation of your fuel and storage systems that includes:

Sampling fuel directly from your tanks

Identifying any contaminants and their sources

Measuring critical fuel quality parameters

Providing a detailed diagnostic report

FAQs
  • They are conditioners designed to improve fuel stability by reducing water contamination, controlling microbial growth, and preventing corrosion. 


    But additives don’t just “treat” fuel — they optimize it, ensuring equipment runs cleaner, longer, and more reliably in all conditions.  By improving fuel performance, additives help extend equipment lifespans, reduce downtime, and lower operational costs and risk.
     

    At Advanced Fuel Solutions, customized fuel additives are part of our comprehensive ACT Fuel Quality Management Program:  Analyze, Consult, Treat.

  • Poor fuel quality can damage equipment and storage tanks, increasing maintenance and repair costs and ultimately reducing customer satisfaction. Since contaminated fuel doesn’t always present with visible symptoms, you should include routine testing in your fuel quality management strategy.

  • It depends on your system's age and cleanliness.  We encourage you to contact us to discuss a recommended frequency based on your unique system and goals.

  • The most common fuel contaminants include water, microorganisms (bacteria, yeast, and fungi), sediment, sludge, and oxidation byproducts.

  • Equipment or engine performance issues

    Increased maintenance or filter changes

    Sludge

    Changes in color or smell 

    Water detected in tanks
