Purpose and Specifications

MOTUL 4100 Protect 10W-40 is a premium synthetic engine oil designed for both petrol and diesel engines in cars, light trucks, and commercial vehicles. This 20-liter container provides reliable engine protection and performance across a wide range of driving conditions.

Key Specifications:

• Viscosity Grade: SAE 10W-40 (flows easily in cold weather, maintains protection at high temperatures)
• API Standards: SL and CF (meets requirements for gasoline and diesel engines)
• Type: Synthetic blend formula
• Volume: 20 liters
• Container: Durable metal drum for storage and handling

The 10W-40 viscosity means the oil starts thin at cold temperatures (10W rating) for quick engine startup, then thickens to a 40-weight at operating temperature to protect engine parts under load and heat.

When to Use and Replace

Suitable For: Petrol and diesel engines in passenger cars, light commercial vehicles, and trucks that specify SAE 10W-40 oil. Always check your vehicle's owner manual to confirm compatibility.

Replacement Schedule: Follow your vehicle manufacturer's recommended oil change intervals, typically every 10,000 to 15,000 kilometers or every 6 to 12 months, whichever comes first. Severe driving conditions (frequent short trips, towing, dusty environments) may require more frequent changes.

Storage: Store in a cool, dry place away from direct sunlight. Properly sealed, this oil maintains quality for several years.

Frequently Asked Questions

Q: Can I use 10W-40 in both winter and summer?
A: Yes. The 10W rating ensures the oil flows properly during cold starts in winter, while the 40-weight provides adequate protection during hot summer driving. This makes it a year-round choice for most climates.

Q: What's the difference between synthetic and conventional 10W-40?
A: MOTUL 4100 Protect is a synthetic blend, offering better oxidation resistance and longer drain intervals than conventional oils. It provides superior protection at extreme temperatures and reduces engine wear over time.

Q: Is this oil suitable for my diesel engine?
A: Yes, the CF rating confirms this oil meets diesel engine requirements. However, always verify your vehicle's manual specifies API CF or a compatible standard before use.
