Why Do I Need a Diesel Fuel Stabilizer for Bulk Tanks?

Diesel fuel in bulk tanks can sit for weeks, months, or longer before it is used. During that time, fuel can be affected by oxidation, water contamination, heat, microbes, and sediment formation.

Why Stored Fuel Changes

Fuel storage problems are often caused by a combination of time, oxygen exposure, temperature swings, water, and contamination. As fuel ages, it may darken, form gums or sediment, plug filters, and perform poorly.

Best Practices for Bulk Tanks

• Keep tanks as clean and dry as possible.
• Reduce water entry from condensation, leaks, or poor caps and vents.
• Inspect and drain water separators when needed.
• Use a fuel stabilizer before long-term storage problems develop.
• Rotate fuel when possible instead of letting it sit indefinitely.
