Frequently Asked Questions
For most stored diesel applications, annual polishing is the recommended minimum. Tanks located in high-humidity regions such as Louisiana, or those dedicated to emergency generator backup power, often benefit from biannual service to ensure fuel remains fully reliable and contaminant-free.
Key indicators include discolored or hazy fuel, a sharp acidic odor, visible sludge or slime deposits, repeatedly clogged fuel filters, and difficulty starting engines. These symptoms point to water intrusion, microbial infestation, or oxidation — all of which call for professional intervention.
No tank draining is necessary. The polishing process works with fuel already in the tank, recirculating it through filtration equipment and returning it cleaned and conditioned. This approach keeps operational disruption minimal and eliminates the need for any planned downtime.
Moisture accumulates inside diesel tanks mainly through condensation driven by daily temperature swings, through breather vents that allow humid outside air to enter, and occasionally from water-contaminated fuel deliveries. Left unaddressed, the free water that settles to the tank bottom rapidly encourages dangerous microbial growth.
