SUSTAINABLE PERFORMANCE: GUARDOL® ECO® (SYNTHETIC BLEND)
Maximum Efficiency. Lower Carbon Footprint.
Mammoth is proud to provide Phillips 66® Guardol Eco, the premium synthetic blend engine oil designed for fleets looking to maximize fuel economy without compromising on durability. Engineered specifically to meet the high demands of 2017 and newer EPA-compliant engines, this "Eco" formulation reduces internal engine friction and drag, helping you squeeze every possible mile out of your fuel budget while maintaining elite wear protection.
WHY MAMMOTH TRUSTS GUARDOL® ECO:
Fuel Economy Leader: Optimized for lower viscosity (FA-4) standards, reducing parasitic power loss within the engine to deliver measurable improvements in fuel efficiency.
Liquid Titanium® Shield: Fortified with our exclusive titanium additive to provide a molecular-level protective layer, ensuring your fuel-saving oil doesn't sacrifice an ounce of wear defense.
Modern Emission Protection: Fully compatible with DPF, DOC, and SCR systems, designed specifically to handle the higher operating temperatures of the latest generation of diesel engines.
Oxidation Resistance: Advanced synthetic blend chemistry prevents oil breakdown and thickening, allowing for clean operation and stable performance across extended service intervals.

MAMMOTH TECHNICAL TIP:
This is a specialized "Fuel Economy" oil. It’s thinner than your standard 15W-40, so don't put it in an older engine. But for new rigs designed for FA-4, it provides the same wear protection as a thicker oil while noticeably cutting your fuel bill.
