Purpose and Specifications

WOLF GUARDTECH 15W50 SL/CF is a semi-synthetic engine oil engineered for modern gasoline and diesel engines, including turbocharged vehicles. This oil delivers superior engine cleanliness by minimizing oxidation and providing robust protection against sludge, soot, and piston deposits that accumulate over time.

The 15W50 viscosity rating means the oil flows easily in cold winter conditions (down to -39°C) while maintaining a stable, protective film at high engine temperatures. This dual-temperature performance ensures your engine stays protected whether you're starting on a freezing morning or driving in heavy traffic.

Key Performance Benefits:

• Keeps engines clean in all driving conditions
• Protects catalytic converters and emission systems
• Resists aging and breakdown from heat stress
• Meets Mercedes-Benz 229.1 specification and ACEA A3/B3-16 and A3/B4 standards
• Suitable for both naturally aspirated and turbocharged engines

When to Use / Replace?

Replace this oil every 10,000 to 15,000 kilometers or every 6 to 12 months, whichever comes first. If you drive in severe conditions (frequent short trips, towing, dusty environments), replace every 8,000 kilometers or 6 months. The 5-liter container is ideal for a single oil change on most passenger cars, with potential for a second top-up depending on your vehicle's capacity.

This oil operates safely between -39°C and approximately 100°C, making it suitable for temperate and cold climates. Store unopened containers in a cool, dry place; shelf life is typically 3 to 5 years when properly stored.
