GUARDOL ECT® SYNTHETIC BLEND DIESEL ENGINE OIL

PREMIUM SYNTHETIC BLEND API CK-4 DIESEL ENGINE OIL; FORTIFIED WITH LIQUID TITANIUM PROTECTION ADDITIVE

Close


THE VERSATILE WORKHORSE: GUARDOL® ECT® (SYNTHETIC BLEND) Performance Redefined. Built for Modern Emissions Standards.


Mammoth is proud to supply Phillips 66® Guardol ECT (Emission Compatible Technology), a premium-quality, part-synthetic API CK-4 engine oil. Specifically developed for four-stroke cycle diesel engines meeting 2007 and later EPA on-highway exhaust emissions standards, this formulation is the industry standard for protecting engines equipped with DPF, DOC, and SCR systems. It is fully backward serviceable, providing a high-performance solution for both your newest assets and your legacy pre-2007 fleet.


WHY MAMMOTH TRUSTS GUARDOL® ECT:

  • Emission System Integrity: Specially formulated for total compatibility with modern exhaust aftertreatment hardware, ensuring your DPF, DOC, and SCR systems remain efficient and clog-free.

  • Liquid Titanium® Protection: Fortified with exclusive Liquid Titanium® additive technology to provide a molecular-level shield against wear and friction in high-load, high-heat environments.

  • Backward Serviceability: While engineered for the latest EPA standards, its robust chemistry provides premium protection and extended life for older diesel engines requiring CJ-4 or CI-4.

  • Oxidation & Soot Control: Advanced synthetic blend chemistry fights oil thickening and sludge buildup, maintaining optimal viscosity and engine cleanliness even under severe service conditions.

PRODUCT RESOURCES 

PERFORMANCE

  • Thermal Stability: Superior resistance to oil thickening and breakdown under the extreme heat of heavy-load cycles.

  • Fuel Economy: Lower internal friction compared to conventional oils, helping maximize MPG across the fleet.

  • Oxidation Control: Advanced synthetic chemistry prevents sludge and varnish, keeping the top-end of the engine "factory clean."

PROTECTION

  • Wear Defense: High-performance anti-wear additives provide a robust sacrificial layer for cams, rollers, and rings.

  • Viscosity Retention: Shear-stable polymers ensure the oil stays "in grade" even during extended drain intervals.

  • Corrosion Shield: Neutralizes acidic combustion byproducts to protect bearings and yellow metals from chemical attack.

UPTIME

  • Extreme Cold Flow: Excellent low-temperature pumpability ensures vital oil reaches engine components instantly during sub-zero starts.

  • Interval Extension: Engineered for the longest drain intervals allowed by OEMs, keeping trucks on the road and out of the shop.

  • Aftertreatment Life: Low-SAPS formula reduces DPF clogging, minimizing forced regenerations and costly sensor replacements.

FEATURES & BENEFITS

  • Liquid Titanium® Protection: Exclusive additive bonds to engine parts at a molecular level to reduce wear in high-stress areas.

  • Soot Control: Advanced dispersants keep soot in suspension, preventing abrasive wear and oil thickening.

  • Oxidation Resistance: Resists thermal breakdown, allowing for safely extended drain intervals in modern diesel engines.

  • Aftertreatment Friendly: Low-ash formulation protects Diesel Particulate Filters (DPF) and Selective Catalytic Reduction (SCR) systems.

  • Shear Stability: Stays in grade even under the punishing mechanical stress of heavy-haul trucking.

APPLICATIONS

  • 2007+ EPA-compliant low-emission diesel engines using Ultra-Low Sulfur Diesel (ULSD).

  • Heavy-duty trucks in on-highway and off-highway service (Construction, Mining, Logging).

  • Mixed fleets containing both newer low-emission and older diesel engines.

  • Tier 4 final engines requiring a CJ-4 or CK-4 category lubricant.

MAMMOTH TECHNICAL TIP:

This is our most popular diesel oil for Island fleets. The Liquid Titanium acts like a "sacrificial shield" on the cylinder walls and cam lobes. It’s specifically engineered to handle the high heat and soot loads of modern EGR engines, ensuring your top-end stays clean and your bearings stay protected.
