PRECISION ENDURANCE: GUARDOL® TT® (SYNTHETIC BLEND)
Total Protection. Advanced Deposit Control.
Mammoth is proud to supply Phillips 66® Guardol TT, a premium synthetic blend engine oil designed for high-output diesel engines operating under severe conditions. This formulation is specifically engineered to provide superior TBN retention and deposit control, making it an exceptional choice for fleets that demand high-level engine cleanliness and long-term durability in heavy-duty cycles.
WHY MAMMOTH TRUSTS GUARDOL® TT:
Acid Neutralization: Features a robust TBN (Total Base Number) profile that effectively neutralizes acidic combustion byproducts, protecting vital engine bearings from corrosive wear.
Piston Cleanliness: Advanced detergent technology minimizes the formation of carbon and lacquer on pistons and ring grooves, ensuring optimal compression and power.
Liquid Titanium® Shield: Fortified with our exclusive titanium additive to create a molecular-level barrier on engine surfaces, significantly reducing wear in high-pressure contact zones.
Synthetic Blend Stability: Offers enhanced thermal stability and oxidation resistance compared to conventional mineral oils, keeping the oil "in-grade" even during the most demanding haulage.
PRODUCT RESOURCES
PERFORMANCE
Acid Neutralization: Features a robust TBN profile that neutralizes acidic combustion byproducts to protect vital engine bearings from corrosion.
Piston Cleanliness: Advanced detergent technology minimizes carbon and lacquer buildup on pistons to maintain optimal compression.
Liquid Titanium® Shield: Creates a sacrificial barrier on engine surfaces to significantly reduce wear in high-pressure contact zones.
PROTECTION
Piston Ring Defense: Prevents carbon and lacquer from sticking rings, ensuring a perfect seal for maximum compression and power.
Bore Polish Resistance: Maintains a consistent cylinder wall texture to optimize oil consumption and prevent "glassy" bore wear.
Superior Bearing Protection: Formulated to stay on metal surfaces even after shutdown, providing vital protection during the next start-up.
UPTIME
Power Retention: By keeping rings and valves clean, this oil ensures engines maintain factory-spec horsepower and torque throughout their service life.
Reduced Oil Top-Offs: Superior volatility control means less oil is "burned off," keeping sumps full and reducing the need for mid-interval additions.
Internal Integrity: Minimizes the buildup of abrasive contaminants, reducing the frequency of costly engine overhauls and mid-life repairs.

MAMMOTH TECHNICAL TIP:
The "TT" stands for Truck Tested, and it’s the workhorse of the lineup. If you’re looking for a no-nonsense, high-quality 15W-40 that satisfies both your late-model emission-controlled trucks and your older iron, this is your primary candidate. It’s the definition of "fleet standard."
