Purpose and Specifications

MOTUL 8100 X-CESS 5W40 is a premium 100% synthetic engine oil engineered for modern high-performance gasoline and diesel engines. This 5-liter bottle delivers advanced protection for naturally aspirated, turbocharged, and direct-injection engines found in contemporary vehicles.

Key Performance Data:

• Viscosity Grade: SAE 5W-40 (flows smoothly in cold starts down to -36°C / -32.8°F)
• Density: 0.850 g/cm³ at 20°C (68°F)
• Viscosity at 100°C (212°F): 14.2 mm²/s for reliable high-temperature protection
• HTHS Viscosity at 150°C (302°F): 3.7 mPa.s (maintains film strength under extreme heat)
• Flash Point: 230°C (446°F) – safe handling and storage
• Pour Point: -36°C (-32.8°F) – excellent cold-weather performance
• TBN (Total Base Number): 10.1 mg KOH/g – neutralizes engine acids and extends oil life

When to Use / Replace?

Replacement Intervals: Follow your vehicle's owner manual for exact drain intervals. Most modern engines with this oil specification allow extended drain intervals of 10,000–15,000 km (6,000–9,000 miles) or 12 months, whichever comes first. Some vehicles with on-board oil monitoring systems may extend to 20,000 km (12,400 miles).

Operating Temperature Range: Effective from -36°C (-32.8°F) cold starts to sustained engine temperatures of 100°C (212°F) and beyond. Maintains protective film strength even at 150°C (302°F) under high-load conditions.

Storage Life: Store in a cool, dry place. Unopened bottles remain stable for 3–5 years when kept away from direct sunlight and extreme temperatures.

Best For: Premium sedans, sports cars, and diesel vehicles from BMW, Mercedes-Benz, Porsche, Volkswagen, Renault, FIAT, and other manufacturers requiring ACEA A3/B4 or equivalent specifications. Ideal for turbocharged engines and vehicles still under warranty.

Frequently Asked Questions

Q: Can I use this oil in my older car?
A: Check your owner's manual first. This oil is designed for modern engines (roughly 2000 onward). Older vehicles may require different viscosity grades or specifications. Using the wrong oil can void warranties or damage engines.

Q: Is this oil suitable for diesel engines?
A: Yes. MOTUL 8100 X-CESS 5W40 is approved for both gasoline and diesel engines, including turbocharged diesels. It meets GM LL-B-025 (diesel) and other diesel-specific standards. Always verify your vehicle's manual.

Q: How often should I check the oil level?
A: Check oil level monthly or before long trips. Modern synthetic oils like this one break down slowly, but levels can drop due to normal consumption (especially in high-performance engines). Top up if below the minimum mark on the dipstick.
