TotalEnergies Rubia Optima 1100 15W-40 is an advanced, premium-technology heavy-duty diesel engine oil formulated to meet the latest API CK-4 specification. Developed using Inno-Boost technology, it delivers maximum wear defense, superior oxidation stability, and enhanced engine protection for modern heavy commercial vehicles, buses, construction equipment, and agricultural machinery operating under severe conditions.

Designed to safeguard advanced exhaust after-treatment systems, its low-SAPS formulation protects Diesel Particulate Filters (DPFs) against premature ash loading while ensuring full compatibility with Selective Catalytic Reduction (SCR) units. The practical 20-litre drum provides a manageable, convenient volume for commercial fleet workshops, on-site maintenance vehicles, and heavy equipment servicing.

Key Performance Benefits

• API CK-4 Performance Defense: Meets and exceeds stringent modern heavy-duty diesel standards, offering significantly improved oxidation resistance and shear stability compared to older API CJ-4 oils.
• Low-SAPS Exhaust System Protection: Low-ash technology prevents DPF blocking and preserves the operational efficiency of SCR emission control systems.
• Inno-Boost Technology: Advanced chemistry increases oil film resistance under high pressures and temperatures, reducing mechanical engine wear and extending component life.
• Exceptional Thermal & Oxidation Stability: Fights high-temperature oil thickening, sludge formation, and varnish deposits under continuous heavy-payload operation.
• Broad Fleet & OEM Compatibility: Suitable for modern Euro VI and American heavy-duty engines while remaining fully backward-compatible with older vehicle fleets.
• Practical Workshop Drum: 20-litre capacity offers easy handling, clean pouring, and mobile utility across service bays and job sites.
