This high-performance oil provides reliable protection across a wide temperature range, flowing smoothly during cold winter starts while maintaining engine protection during hot driving conditions.

Key Benefits:

• Fully synthetic formula extends engine life and reduces wear on critical components
• Works in temperatures from cold winter conditions to high-heat summer driving
• Helps reduce harmful emissions from your vehicle
• Approved for modern fuel injection and multi-valve engine designs
• Suitable for both petrol and diesel powerplants

When to Use and Replace

Replace your engine oil every 10,000 to 15,000 kilometers or 12 months, whichever comes first. If you drive in severe conditions (frequent short trips, towing, or dusty environments), replace more frequently—every 8,000 to 10,000 kilometers. Always check your vehicle's owner manual for specific recommendations.

This oil operates safely between -20°C and +100°C, making it suitable for year-round driving in most climates. Store unopened bottles in a cool, dry place with a shelf life of approximately 5 years.
