Totalenergies Rubia TIR 7400 10W-40 is a high-performance, synthetic-technology heavy-duty diesel engine oil designed to meet the demanding requirements of commercial vehicles, buses, and off-highway machinery. Formulated with advanced anti-wear and detergent chemistry, it provides outstanding thermal stability and soot-handling performance under continuous heavy loading.

Specifically engineered to support extended oil drain intervals (ODI) on Euro 3, Euro 4, and Euro 5 diesel engines (non-DPF), Totalenergies Rubia TIR 7400 delivers exceptional engine cleanliness, bore-polishing protection, and wear resistance across mixed-fleet operations.

Key Performance Benefits

• Extended Drain Capability: High thermal resistance and shear stability allow for prolonged oil drain intervals according to OEM recommendations.
• Superior Soot Dispersancy: Keeps soot particles suspended to prevent sludge formation, filter plugging, and oil thickening in heavy-duty applications.
• Bore-Polishing Protection: Formulated to protect cylinder liners against bore polishing, maintaining compression and controlling oil consumption.
• Advanced Anti-Wear & Anti-Corrosion: Neutralizes corrosive combustion acids and shields high-stress engine components against wear during cold starts and severe operating conditions.
• Piston Cleanliness: Highly effective detergent additives prevent ring-sticking and harmful carbon deposits on pistons at elevated operating temperatures.
• Mixed-Fleet Efficiency: High multi-brand compatibility helps simplify lubricant inventories for transport fleets, construction, and agricultural equipment.
