Fuel polishing is a technical cleaning process that removes water, sediment, and microbial contamination (often called "fuel bugs") from stored diesel. It is necessary because diesel fuel naturally degrades over time. Without regular polishing, these contaminants can clog filters, damage fuel injectors, and cause engine failure during critical moments like power outages.
Common signs of fuel contamination include a dark or "sludgy" appearance, a foul odor similar to varnish, and "hazy" or cloudy fuel. Mechanically, you may notice your generator or engine sputtering, frequent filter changes, or excessive black smoke. A professional fuel laboratory test is the only way to confirm exact contamination levels.
In the Florida and Texas climates, high heat and humidity accelerate microbial growth and condensation. We recommend professional fuel testing every 6 to 12 months. For critical backup systems like hospitals or data centers, fuel polishing should be performed annually to meet NFPA 110 standards and ensure 100% reliability during emergency events.
Yes, fuel polishing is significantly more cost-effective and environmentally friendly than fuel replacement. Polishing restores your existing fuel to "pristine" ASTM standards for a fraction of the cost of new fuel. Additionally, because fuel is a hazardous material, polishing avoids the high costs and regulatory hurdles associated with hazardous waste disposal.
