Purpose and Specifications

ORLEN PLATINUM CLASSIC DIESEL MINERAL 15W-40 1L is a reliable mineral multigrade engine oil designed for diesel engines in older passenger cars, vans, and light commercial vehicles. Its 15W-40 viscosity ensures smooth flow in cold starts down to -37°C while staying thick enough for hot summer operation up to 40°C. This oil meets API CF standards, protecting against wear, reducing leaks, and handling everyday city and highway driving year-round.

Perfect for vehicles several years old or with high mileage, it works well with turbocharged engines and basic exhaust systems like EGR. Store sealed bottles in a cool, dry place between -20°C and 40°C for a shelf life of up to 4-5 years.

When to Use / Replace?

Use this oil in diesel engines where manufacturers recommend API CF or lower grades, especially for mixed city/highway use or dual-fuel setups. Replace every 7,500-15,000 km or 6-12 months, depending on driving conditions like frequent short trips, idling, or dusty roads. Check oil levels regularly in high-mileage engines over 150,000 km to prevent consumption issues.
