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.

PRODUCT RESOURCES
PERFORMANCE
Extreme Temperature Mastery: Provides enhanced thermal stability and resistance to viscosity breakdown compared to conventional oils, ensuring consistent performance in high-heat environments.
Low-Temperature Precision: Features excellent low-temperature pumpability, allowing for faster oil circulation and easier starts during cold morning operations.
Reduced Oil Consumption: Engineered with low volatility to minimize oil burn-off, ensuring more consistent oil levels and better efficiency between service intervals.
PROTECTION
Advanced TGDI Shield: Specifically formulated to combat Low-Speed Pre-Ignition (LSPI), protecting high-tech turbocharged gasoline direct-injection engines from internal damage.
Corrosion & Foam Defense: Guards against rust, bearing corrosion, and foaming, maintaining a robust lubricating film even under severe high-speed driving conditions.
Warranty Compliance: Exceeds the latest ILSAC GF-7A requirements, ensuring full protection and compliance for new vehicles under manufacturer warranty.
UPTIME
Engine Cleanliness: Actively resists the formation of sludge and varnish, keeping vital engine components clean and reducing the need for unscheduled maintenance.
Thermal Breakdown Resistance: Outstanding resistance to high-temperature thinning means your oil maintains its protective properties longer, supporting engine longevity.
Reliable Cold Starts: By ensuring rapid lubrication at startup, it minimizes the metal-on-metal wear that occurs during the first few seconds of engine operation, keeping your fleet on the road.

FEATURES & BENEFITS
LSPI Protection: Advanced chemistry prevents Low-Speed Pre-Ignition in turbocharged gasoline direct-injection engines.
Sludge Defense: Exceptional resistance to sludge and varnish formation keeps internal engine components spotless.
Cold Start Flow: Full-synthetic base ensures rapid oil pressure and lubrication in sub-zero Vancouver Island winters.
Volatility Control: Low-evaporation formula reduces oil consumption and maintains viscosity under high heat.
Turbo Shield: Specifically engineered to protect high-temp turbocharger bearings from "coking" and carbon buildup.
APPLICATIONS
Modern turbocharged gasoline direct-injection (TGDI) engines.
Passenger cars and SUVs requiring GM dexos1® Gen 3 specifications.
High-performance gasoline engines operating in extreme stop-and-go traffic.
Flex-fuel vehicles operating on ethanol-containing fuels up to E85.
