SHIELD® DEFENSE
SYNTHETIC BLEND PASSENGER CAR ENGINE OIL FOR HIGH MILEAGE VEHICLES; BLENDED WITH HIGH MILEAGE BOOSTER
PREMIUM AUTOMOTIVE PERFORMANCE: SHIELD® DEFENSE (HIGH MILEAGE SYNTHETIC BLEND)
Engineered for Longevity. Built for Protection.
Mammoth is proud to supply Phillips 66® Shield Defense, the specialized synthetic blend solution designed to extend the life of your fleet. Whether you are managing high-mileage vehicles that need extra care or newer cars still under warranty, this formulation is built with a proprietary High Mileage booster. It provides a superior seal and enhanced protection that conventional oils can't match, ensuring your engines stay on the road longer—no matter the odometer reading.
WHY MAMMOTH TRUSTS SHIELD® DEFENSE:
High-Mileage Restoration: Formulated with a proprietary booster that maximizes performance and extends engine life for older vehicles, while remaining fully compatible with newer models.
LSPI & Turbo Protection: Engineered to combat Low-Speed Pre-Ignition (LSPI), providing critical protection for high-tech turbocharged gasoline direct injection engines.
Superior Deposit Control: Our advanced synthetic blend resists viscosity breakdown, sludge, and varnish formation better than conventional oils, keeping internal engine components cleaner and more efficient.
Fuel Economy & Versatility: Meets "Resource Conserving" standards for improved fuel economy and emission system protection, supporting everything from standard gasoline to E85 flex-fuel systems.
PRODUCT RESOURCES
PERFORMANCE
High Mileage Booster: Features a proprietary additive package designed to maximize performance and extend engine life in vehicles with high odometer readings.
Seal Conditioning Tech: Formulated to treat and condition engine seals, helping to reduce oil consumption and minimize leaks in older engines.
Superior Viscosity Retention: Synthetic blend formulation provides better resistance to thinning and breakdown than traditional conventional engine oils.
PROTECTION
Life Extension Shield: Actively battles the unique wear patterns of older engines while providing the LSPI protection required for modern turbocharged systems.
Sludge & Varnish Combat: Specialized chemistry breaks down and prevents the buildup of internal deposits that often plague high-mileage assets.
Modern Hybrid Compatibility: While optimized for high mileage, it remains ideal for newer cars under warranty, including gasoline-electric hybrids.
UPTIME
Reduced Maintenance Costs: By fighting oil consumption and preventing leaks, Shield Defense keeps your high-mileage fleet on the road with fewer top-ups.
Maximized Asset Life: Extends the useful life of aging vehicles, delaying the need for costly engine replacements or major overhauls.
Reliable Operational Health: Ensures consistent oil pressure and cooling for high-mileage engines that may be subject to increased thermal stress.

FEATURES & BENEFITS
Seal Rejuvenation: Active seal conditioners swell and soften older gaskets to stop or prevent oil leaks.
Consumption Reduction: High-viscosity formula helps fill clearances in worn engines to reduce "burn-off."
Deposit Shield: Extra detergents clean out existing sludge while preventing new varnish from forming.
Friction Modifiers: Reduces internal friction to help older engines run cooler and more efficiently.
Catalyst Safe: Phosphorus-optimized formula protects expensive catalytic converters from fouling.
APPLICATIONS
Vehicles with over 120,000 kilometers (75,000 miles) on the odometer.
Engines showing signs of minor oil consumption or driveway spotting.
High-mileage light trucks used for towing or heavy commuting.
Older passenger cars requiring a robust, stay-in-grade lubricant.
