Purpose and Specifications

MOTUL 4100 POWER 15W-50 is a semi-synthetic engine oil engineered for high-performance gasoline and diesel engines. This oil delivers superior protection across all driving conditions—city, highway, and heavy use—while maintaining engine cleanliness and reducing internal wear.

Key Performance Features:

• Keeps your engine clean by preventing sludge and black deposits that clog internal passages
• Reduces friction between moving engine parts, extending engine life and improving fuel efficiency
• Protects against rust and corrosion, especially important in humid or coastal climates
• Maintains consistent thickness from cold winter starts (-30°C / -22°F) to high-temperature highway driving (100°C / 212°F)
• Works with all fuel types: unleaded gasoline, diesel, LPG, and biofuels

Approvals: ACEA A3/B4, API SL/CF, Mercedes-Benz MB 229.1H, VW 501.01 & 505.00

When to Use and Replace?

Best For: Turbocharged and naturally aspirated engines, multi-valve designs, engines with fuel injection or carburetors, vehicles with or without catalytic converters. Ideal for engines prone to oil consumption due to its high viscosity at operating temperature.

Replacement Interval: Follow your vehicle manufacturer's recommended drain interval. Typical intervals range from 10,000 to 15,000 km (6,000 to 9,000 miles) or 6 to 12 months, whichever comes first. Check your owner's manual for exact specifications.

Storage: Store in a cool, dry place. Semi-synthetic oils maintain stability for extended periods when properly sealed.

Frequently Asked Questions

Q: Can I mix MOTUL 4100 POWER with other oils?
A: Yes, this oil can be safely mixed with other synthetic or mineral oils if needed during top-ups. However, complete oil changes with the same product provide optimal performance.

Q: Is this oil suitable for older engines?
A: Yes. The 15W-50 viscosity and high zinc content make it excellent for classic and vintage engines, including flat-tappet designs. It provides robust protection for engines built before modern low-ZDDP requirements.

Q: Will this thicker oil (15W-50) cause cold-start problems?
A: No. The 15W rating ensures easy flow at -30°C, so winter starts remain smooth. The oil thins just enough to circulate quickly, then thickens to protective levels once the engine warms up.
