Test Process

Test Procedure and Parameters:

  • Two samples were analyzed: standard ULSD and ULSD + DF5.

  • Tests included:

    • Visual Inspection (ASTM D4176)

    • Copper Corrosion (ASTM D130)

    • Distillation (ASTM D86)

    • Flash Point (ASTM D93)

    • Density (ASTM D4052)

    • And other standard measures of diesel fuel quality.

KEY FINDINGS

Improved Corrosion Resistance: DF5 enhanced the copper corrosion rating from 1b to 1a, suggesting better protection against corrosion, a crucial factor for engine longevity.

  • Improved Corrosion Resistance
    DF5 improved the copper corrosion rating from 1b to 1a, providing stronger protection against fuel system corrosion — a major factor in extending engine life.

  • Cold Weather Stability
    Cloud point and cold filter plug point results showed equal or slightly better cold-weather performance, keeping operations reliable in varying climates.

  • No Negative Impact on Core Properties
    Key measures like ash content, cetane index, and carbon residue remained consistent, proving DF5 does not degrade fuel quality.

  • Maintains Essential Fuel Characteristics
    Flash point, density, and API gravity stayed within optimal ranges, showing DF5 preserves the fuel’s critical safety and performance standards.

Why It Matters for Fleets

For fleet operators, these results confirm that DF5:

  • Protects engines with improved corrosion resistance

  • Supports reliable operation in cold environments

  • Maintains compliance with diesel fuel standards

  • Reduces maintenance risks and costs by keeping core properties stable

Conclusion

Peak Petroleum Testing Services Inc. confirms that DF5 enhances diesel fuel performance without compromising its integrity. Operators can trust DF5 to deliver cleaner, more reliable combustion, extending both fuel and engine performance in real-world conditions.
