Purpose and Specifications

Engine oil TOTAL 5W30 RUBIA OPTIMA 3500 FE 20L is a fully synthetic, low-SAPS diesel engine oil designed for heavy-duty trucks, buses, and Euro VI engines from brands like MAN, Scania, Volvo, Daimler, Iveco, DAF, Cummins, and Ford. Its Fuel Economy technology saves 1% fuel on average versus SAE 40 oils, reaching up to 3% savings when paired with matching transmission fluids. The 5W-30 viscosity flows easily for cold starts down to -30°C, stays stable up to 130°C in extreme tests, and cuts oxidation by up to 100% for longer protection.

Approved for ACEA E4/E6/E7/E8/E9/E11, API CK-4/CJ-4/CI-4/CH-4, and OEM specs like MAN M3777, Volvo VDS-4.5, it prevents DPF clogging, reduces wear by up to 81% on key parts, and supports extended drain intervals up to 150,000 km. Inno-Boost antioxidants keep viscosity steady, minimizing deposits and extending post-treatment system life in high-soot, biodiesel conditions.

When to Use / Replace?

Use in modern Euro 6 diesel engines with DPF/SCR for daily hauls, long-distance trucking, or specialty vehicles needing fuel savings and max intervals. Ideal for high-torque engines running hot or cold extremes. Replace every 100,000-150,000 km or 12-24 months per manufacturer guidelines, or sooner if monitoring shows high soot. Shelf life is 5 years stored below 60°C away from sunlight.

FAQ

Q: Does it work in older engines?
A: Yes, it's backward-compatible with many pre-Euro VI diesels meeting ACEA E4-E9, replacing older Rubia Tir oils while boosting efficiency.

Q: How much fuel can I really save?
A: Expect 1-3% savings in real-world use, confirmed in tests, especially with Fuel Economy gear oils.

Q: Safe for DPF-equipped trucks?
A: Absolutely - low-SAPS formula prevents filter clogging and extends durability in Euro VI systems.
