TotalEnergies Rubia TIR 7400 15W-40 Mineral Diesel Engine Oil

• TotalEnergies Rubia TIR 7400 15W-40 is a high-performance mineral lubricant used in on-road diesel technology. It is recommended for Euro 3 and previous engines of most European and American manufacturers, and is also adapted to Euro 5 and previous engines of some manufacturers with appropriate oil drain intervals. 
   
• Formulated with Pro-Efficient Technology, it protects and improves the efficiency of professional engines by ensuring reduced mechanical wear and extended oil drain intervals, meaning longer engine life, fewer breakdowns, and reduced maintenance costs. Rubia TIR 7400 15W-40 enables coverage of a mixed-brand fleet (American and European manufacturers) with a minimal number of products.

Benefits of Using TotalEnergies Rubia TIR 7400 15W-40

• Pro-Efficient Technology Superior Wear Protection: Forms a strong protective layer on all metal surfaces to avoid direct contact between moving engine parts, minimising mechanical wear by up to 81% compared to ACEA E4 industry limits, ensuring longer engine life and fewer breakdowns.
• Extended Oil Drain Intervals: Advanced additive package maintains oil performance under severe operating conditions, supporting extended drain intervals to reduce maintenance frequency and lower total operating costs for commercial fleets.
• Excellent Viscosity Stability in Service: Maintains its viscosity grade throughout the oil drain interval, even under the severe thermal and mechanical stresses of modern heavy-duty diesel engines, guaranteeing effective engine lubrication at all times.
• Outstanding Detergent, Dispersant & Anti-Wear Properties: Keeps the engine clean and enables efficient control of soot, sludge, and piston deposits, protecting critical engine components and preserving performance throughout the service interval.
• Excellent Bore Polishing Protection: Specifically formulated to resist bore polishing, a form of cylinder wear particularly common in heavily loaded diesel engines operating under severe duty cycles.
• Mixed-Brand Fleet Simplification: With 200+ approvals from heavy vehicle manufacturers and compatibility with both American and European engines, one product covers a wide range of trucks and buses, minimising lubricant inventory and reducing the risk of misapplication.
   

Ideal Applications

FAQ

• What is Pro-Efficient Technology? 
  Pro-Efficient Technology is TotalEnergies’ exclusive technology for professional engines. Its right combination of extra-resistant anti-wear molecules and viscosity modifiers that form a strong protective layer on all metal surfaces, minimising mechanical wear and extending engine life, resulting in increased efficiency and profitability for your business.
• Is this oil suitable for Euro 6 engines? 
  No. Rubia TIR 7400 15W-40 is formulated for Euro 2 and Euro 3 engines, and is adapted to Euro 5 for select manufacturers with appropriate drain intervals. For Euro 6 engines, TotalEnergies recommends higher-tier products such as Rubia TIR 9900 or the Rubia Optima range.
• Can this oil be used in engines fitted with DPF systems?
  No. This product is a mineral oil and is not formulated with Low-SAPS technology. It is not suitable for engines equipped with diesel particulate filters (DPF) or other exhaust after-treatment systems. The Rubia Optima range should be used for such applications.
• Does it cover multiple truck brands? 
  Yes. With 200+ approvals from heavy vehicle manufacturers, Rubia TIR 7400 15W-40 covers Cummins, Mack, MAN, Mercedes-Benz, Renault Trucks, Volvo, DAF, IVECO, Scania, ISUZU, and Caterpillar, making it ideal for mixed-brand fleets.
• What drain interval should I follow? 
  Always follow the vehicle manufacturer’s recommended drain intervals as stated in the service manual. The Pro-Efficient Technology supports extended drain intervals where the manufacturer permits, reducing maintenance costs and downtime.
