Purpose and Specifications

Total Rubia Optima 3500 FE 5W-30 is a fully synthetic engine oil designed for modern heavy-duty diesel trucks and buses, especially Euro 6 compliant vehicles from manufacturers like Daimler, Volvo, Scania, MAN, Iveco, and DAF. This premium oil meets the latest API CK-4 specification and is compatible with advanced emission control systems including Diesel Particulate Filters (DPFs) and SCR systems.

Key Performance Benefits:

• Fuel Economy: Saves approximately 1% fuel on average compared to standard oils, with potential savings up to 3% when paired with fuel economy transmission fluids—directly reducing operating costs for fleet operators
• Engine Protection: Advanced low-SAPS formulation prevents DPF clogging and extends the life of post-treatment systems, protecting your investment in modern emission technology
• Extended Oil Change Intervals: Exceptional thermal stability allows longer drain intervals, reducing maintenance frequency and downtime
• Cold Start Performance: 5W viscosity grade ensures reliable engine starting in temperatures as low as -42°C, reducing cold-weather stress on engines
• Oxidation Resistance: Inno-Boost technology provides superior protection against oil breakdown, maintaining viscosity stability throughout the service interval

When to Use / Replace?

Ideal For: Euro 6 heavy-duty trucks, buses, and commercial vehicles with diesel or compatible gas engines equipped with modern emission control systems. Particularly suited for fleets operating in varied climates and seeking reduced fuel consumption.

Oil Change Intervals: Follow your vehicle manufacturer's recommended service schedule. Modern Euro 6 engines with this oil typically allow extended intervals—often 40,000 to 60,000 km or 12 months, whichever comes first. Always consult your owner's manual for exact specifications.

Operating Temperature Range: Performs reliably from -42°C (cold start) to 100°C+ (normal engine operating temperature), with tested stability at extreme conditions up to 130°C in laboratory conditions.

Storage: Store in a cool, dry location. Synthetic oils maintain quality for extended periods when properly sealed and protected from contamination.

Frequently Asked Questions

Q: Will this oil work in my older truck engine?
A: Rubia Optima 3500 FE is specifically formulated for modern Euro 6 engines. While it meets multiple API specifications (CH-4, CI-4, CJ-4, CK-4), compatibility depends on your engine's year and manufacturer. Check your vehicle's manual or contact your dealer to confirm approval for your specific model.

Q: How much fuel will I actually save?
A: Real-world savings average around 1% compared to conventional SAE 40 oils. If you combine this with fuel economy transmission fluid, savings can reach up to 3%. For a truck consuming 30 liters per 100 km, that's roughly 0.3 to 0.9 liters saved per 100 km—meaningful savings over thousands of kilometers annually.

Q: Is this oil safe for DPF-equipped engines?
A: Yes. The advanced low-SAPS (low sulfated ash, sulfur, and phosphorus) formulation is specifically designed to prevent DPF clogging and extend the life of post-treatment systems, making it ideal for modern emission-controlled vehicles.
