PRI-D Gallon Diesel & Kerosene Fuel Stabilizer

Commercial-Grade Bulk Fuel Protection

When you manage larger fuel volumes, fuel stability is not optional — it’s operational insurance. The PRI-D Gallon container is engineered for bulk diesel and kerosene storage systems requiring consistent long-term stabilization and oxidation control.

Designed for ULSD and biodiesel blends, PRI-D helps prevent fuel breakdown, sludge formation, and filter plugging in stored fuel. Whether used in agricultural tanks, municipal reserves, fleet programs, or standby power systems, this gallon size delivers scalable protection with measurable cost efficiency.

🛢 Built for Bulk Diesel Storage Systems

One gallon of PRI-D treats up to 2,048 gallons of diesel fuel at the standard maintenance ratio.

Ideal for:

• Bulk storage tanks
• Agricultural fuel systems
• Construction companies
• Fleet maintenance operations
• Municipal fuel programs
• Backup generator installations
• Marine fuel depots

This size reduces cost per treated gallon and ensures consistent treatment across multiple tanks.

Why Choose the Gallon Size?

Unlike small-bottle users, bulk fuel managers face different risks:

• Long fuel turnover cycles
• Temperature fluctuations
• Large storage tank exposure
• Higher financial loss from degraded fuel

The PRI-D Gallon format supports scheduled fuel maintenance programs and tank treatment protocols, helping preserve fuel chemistry and maintain combustion reliability over extended storage periods

Treatment Capacity & Cost Efficiency

Standard Treatment Ratio:
1 oz treats 16 gallons

Gallon Capacity:
128 oz total

Total Treatment Capability:
Up to 2,048 gallons per container

For higher-risk or aged fuel, increased dosage may be applied per manufacturer guidelines.

🔬 Engine & System Benefits

• Helps stabilize stored diesel and kerosene
• Reduces oxidation-related sludge formation
• Supports cleaner combustion
• Helps preserve injector and fuel system cleanliness
• Compatible with ULSD and biodiesel blends

PRI-D contains no cetane improvers and does not alter fuel specifications.

 Who Should Use PRI-D Gallon?

Choose the gallon size if you:

• Maintain 500+ gallon storage tanks
• Operate multiple diesel assets
• Manage agricultural fuel supply
• Support emergency generator programs
• Require predictable fuel reliability

For very high-volume operations, consider multi-gallon case quantities for program-level supply continuity.

PRI-D Gallon Bulk Storage FAQ

Will This Fuel Treatment Keep Diesel at a Peak Stability?

Yes. PRI-D maintains diesel fuel at peak stability during extended storage, preventing oxidation and chemical breakdown.

What Is the Shelf Life of PRI?

PRI products have an indefinite shelf life when stored properly in a sealed container.

Why Does PRI Change Color Over Time?

PRI may darken as it reacts with fuel contaminants. This color change indicates it is actively stabilizing and treating the fuel.

If you only need treatment for smaller tanks, the single 32-oz bottle is ideal for seasonal equipment and light storage needs.

For larger fuel tanks or commercial applications, upgrade to the gallon diesel fuel stabilizer for expanded treatment capacity and better cost efficiency.
