Key Performance Benefits:

• Delivers over 3.3% fuel economy improvement compared to standard oils
• Reduces engine wear through advanced anti-wear protection
• Lowers engine operating temperatures for better efficiency
• Protects catalytic converters and works with all gasoline types and biofuels
• Resists oxidation and deposit formation, keeping your engine cleaner longer

When to Use / Replace?

Follow your vehicle manufacturer's recommended drain intervals, typically 10,000 to 15,000 kilometers (6,000 to 9,000 miles) or every 6 to 12 months, whichever comes first. Check your owner's manual for your specific vehicle's requirements, as intervals vary by model and driving conditions.

This 5-liter container provides enough oil for most engine changes with room for top-ups between services. The synthetic formulation offers extended protection, making it suitable for both city and highway driving.

Compatible Vehicles Include: Ford F-150 (multiple generations), Ford EcoBoost engines, Jaguar models, Land Rover vehicles, and select Chrysler and Jeep models requiring low-friction synthetic oil.
