PREMIUM AUTOMOTIVE PERFORMANCE: SHIELD® ARMOR (FULL SYNTHETIC) Engineered for Durability. Built for Efficiency.

Mammoth is proud to supply Phillips 66® Shield Armor, a premium full-synthetic solution designed for those who demand more from their engine oil. By utilizing high-quality synthetic base stocks, Shield Armor provides a significant upgrade over conventional oils, offering superior resistance to thermal breakdown and deposit formation. Whether you are navigating daily commutes or managing a light-duty fleet, this formulation ensures your engine remains protected from the first turn of the key to the end of the service interval.

WHY MAMMOTH TRUSTS SHIELD® ARMOR:

• Superior Thermal Stability: Engineered to resist viscosity breakdown and deposit formation even at high operating temperatures, ensuring consistent protection during long-haul drives. 

• Rapid Cold-Start Protection: Provides faster oil circulation in low temperatures, reducing internal friction and engine wear during those cold West Coast morning starts. 

• Reduced Oil Consumption: The low-volatility synthetic formulation minimizes oil burn-off, leading to more consistent oil levels and fewer top-ups between changes. 

• Advanced Engine Cleanliness: Our full-synthetic chemistry actively fights off sludge and varnish, keeping your internal components clean and maintaining peak engine efficiency for the long term.
