FUEL SYSTEM SPECIFICATIONS

Paraffin Control • Cetane Management • Flow Rate Maintenance

NUMBER 2 DIESEL COMPOSITION

Understanding the molecular behavior of paraffin chains in sub-zero conditions is the difference between a started engine and a stranded rig.

Property Summer Blend Winter Blend Critical Threshold
Cetane Index 48-52 ≥50 Ignition delay ≤0.8ms
Cloud Point +4°C -15°C First visible crystals
Pour Point -2°C -23°C Complete flow cessation
Viscosity @40°C 2.5-4.0 cSt 2.5-3.5 cSt Injector spray pattern integrity
Water Content <0.03% <0.02% Freeze expansion damage

PARAFFIN PRECIPITATION CURVE

Gel Formation Onset
-10°C
Without additive treatment, wax crystals begin network formation at -10°C ambient. Fuel filter plugging occurs within 47 minutes of sustained exposure.
Additive-Extended Limit
-23°C
Polyalphaolefin (PAO) crystal modifiers disrupt lattice growth. Effective concentration: 0.5% by volume. Shelf life: 18 months unopened.
