Purpose and Specifications

TOTAL RUBIA OPTIMA 3100 10W-40 is a premium synthetic diesel engine oil engineered for modern heavy-duty trucks, buses, and commercial vehicles. This oil is specifically formulated to protect engines equipped with advanced exhaust after-treatment systems like diesel particulate filters (DPFs) and selective catalytic reduction (SCR) systems.

The Low-SAPS formulation (low sulphated ash, phosphorus, and sulphur) prevents DPF clogging and extends the life of your after-treatment systems. This means fewer expensive repairs and longer intervals between filter replacements.

Key Performance Features:

• Protects against wear, deposits, and engine sludge buildup
• Maintains oil thickness under extreme heat (up to 130°C engine temperatures)
• Reduces friction for better fuel efficiency
• Excellent corrosion and oxidation protection
• Maintains viscosity stability even under high-stress driving conditions

Approved for: Euro 6 engines from Mercedes-Benz, Volvo, DAF, Renault Trucks, Daimler, Cummins, MAN, Scania, and Iveco. Also suitable for Euro 5 and earlier engines from most manufacturers.

When to Use and Replace?

This oil is designed for extended drain intervals — typically up to 150,000 km or as specified by your vehicle manufacturer. Always follow your truck or bus manufacturer's recommended oil change schedule, as this varies by engine model and driving conditions.

Operating Temperature Range: Flows smoothly at temperatures as low as -33°C and maintains protection at engine operating temperatures up to 130°C.

Shelf Life: Store in a cool, dry place. Unopened containers remain stable for several years when stored properly.

Ideal for: Long-haul trucking, urban bus fleets, mixed-brand fleet operations, and any commercial vehicle requiring Euro 6 compliance with extended service intervals.

Frequently Asked Questions

Q: Can I use this oil in older Euro 5 engines?
A: Yes. While optimized for Euro 6, RUBIA OPTIMA 3100 10W-40 is approved for Euro 5 engines from manufacturers like Iveco and is compatible with most Euro V vehicles, making it ideal for mixed-age fleets.

Q: Will this oil damage my DPF?
A: No. The Low-SAPS technology specifically prevents DPF clogging by reducing ash buildup, actually extending your filter's service life and maintaining engine efficiency.

Q: How often should I check the oil level?
A: Check oil level monthly or before long trips. With extended drain intervals, you'll need fewer top-ups, but regular monitoring ensures optimal engine protection between scheduled changes.
