ADVANCED EFFICIENCY: GUARDOL® FE® (SYNTHETIC BLEND)

Fuel Economy Focused. Uncompromised Protection.

Mammoth is proud to offer Phillips 66® Guardol FE, a premium synthetic blend engine oil specifically engineered to provide enhanced fuel economy compared to standard 15W-40 oils. By utilizing a lower high-temperature high-shear (HTHS) viscosity, Guardol FE reduces internal engine friction and drag, making it the ideal choice for modern fleets looking to lower their total cost of ownership while maintaining a high level of engine wear defense.

WHY MAMMOTH TRUSTS GUARDOL® FE:

• Enhanced Fuel Savings: Formulated to meet the API FA-4 standard, this oil is designed to improve fuel efficiency in 2017 and newer diesel engines without sacrificing oil film strength.

• Liquid Titanium® Shield: Fortified with our exclusive titanium additive to provide a molecular-level layer of protection that guards against engine wear during high-stress operation.

• Superior Oxidation Stability: The synthetic blend base offers excellent resistance to oil thickening and breakdown, ensuring consistent performance over extended service intervals.

• Emission System Compatibility: Low-SAPS formulation ensures your DPF and SCR systems stay clean and operational, reducing the need for forced regenerations and maintenance.
