Purpose and Specifications

WOLF GUARDTECH 10W40 B4 4L is a budget-friendly engine oil that keeps your car running smoothly in everyday conditions. This 10W40 viscosity oil flows easily at cold starts down to -25°C and stays thick up to 150°C, protecting against wear in petrol and diesel engines.

Approved for major brands like FIAT 9.55535-D2/G2, MB 229.1, RENAULT RN0700/RN0710, VW 501.01/505.00, plus ACEA A3/B3/B4 and API SN/CF specs, it meets high standards for cleaning engine internals and reducing friction. The 4-liter pack suits most passenger cars and light vans.

When to Use / Replace?

Use this oil in mixed driving like city traffic, highways, or light off-road where engines hit normal temps. It shines in older vehicles or those with turbochargers needing reliable protection.

• Replace every 10,000-15,000 km or yearly under normal use to keep the engine clean and efficient.
• Shorten to 5,000 km if you do short trips under 8 km, heavy stop-go traffic, or speeds over 170 km/h – this prevents dirt buildup and fuel dilution.
• Shelf life is 3-5 years unopened in cool, dry storage.
