Purpose and Specifications

WOLF OFFICIALTECH 5W30 C4 is a full synthetic engine oil designed for modern gasoline and diesel passenger cars with turbochargers, diesel particulate filters (DPF), and catalytic converters. This oil protects your engine while keeping emission control systems clean and functioning properly.

Key Benefits:

• Low ash formula that prevents DPF clogging and extends filter life
• Superior antioxidants reduce oil breakdown and thickening, maintaining protection throughout the service interval
• Flows easily in winter conditions (down to -39°C) for reliable cold starts
• Stays thick enough at high temperatures (100°C) to protect engine components under load
• Approved by major manufacturers: Renault, Mercedes-Benz, Fiat, Nissan, and Suzuki

Viscosity Grade 5W30: The 5W rating means it flows like a 5-weight oil in winter, while the 30 rating means it maintains the thickness of a 30-weight oil at operating temperature. This balance ensures protection in all seasons without compromising fuel efficiency.

When to Use / Replace?

Replace this oil every 15,000 km or 12 months, whichever comes first. If your vehicle manufacturer specifies longer intervals (up to 20,000 km or 24 months), follow your owner's manual. Use this oil if your vehicle requires:

• ACEA C3 or C4 specification
• Renault RN 0720 approval
• Mercedes-Benz MB 226.51, MB 229.31, or MB 229.51
• Fiat 9.55535-S4

This 1-liter bottle is ideal for top-ups between service intervals or for vehicles with smaller capacity engines. Store in a cool, dry place. Shelf life is typically 3-5 years in unopened containers.

Frequently Asked Questions

Q: Can I use this oil in my older car?
A: Only if your vehicle's manual specifies ACEA C3/C4 or one of the listed manufacturer approvals. Using the wrong oil grade can damage your engine or void your warranty. Check your owner's manual first.

Q: Why is this oil better for diesel engines with DPF?
A: The low-ash formula burns cleaner and produces less residue, which prevents the diesel particulate filter from clogging prematurely. This keeps your emissions system working efficiently and reduces expensive filter replacement costs.

Q: Is synthetic oil worth the extra cost?
A: Yes. Synthetic oils like this one last longer between changes, provide better protection at extreme temperatures, and reduce engine wear. Over time, you'll spend less on oil changes and potentially extend engine life.
