Purpose and Specifications

Comma X-FLOW TYPE-MF 15W40 5L is a high-quality mineral engine oil designed for reliable lubrication in both petrol and diesel vehicles, including fuel-injected, multi-valve, and turbocharged engines. It flows easily during cold starts down to -20°C for quick protection when your engine needs it most, while staying thick enough at operating temperatures up to 100°C to prevent metal-on-metal wear.

This oil keeps your engine clean by suspending soot and dirt particles, neutralizes harmful acids from combustion, and maintains stability under high pressure, extending engine life and cutting maintenance costs. Approved to ACEA A3/B3 and API SL/CF standards, it suits a wide range of cars and light trucks for everyday driving.

When to Use / Replace?

Use Comma X-FLOW TYPE-MF 15W40 in mixed climates where temperatures range from -20°C to 40°C, eliminating the need for seasonal oil swaps. Ideal for normally aspirated or turbo engines up to moderate loads.

• Replace every 10,000-15,000 km or 12 months for standard driving to keep protection strong.
• Shorten to 7,500 km or 6 months for heavy towing, dusty roads, or frequent short trips.
• Shelf life is 5 years when stored in a cool, dry place away from direct sun.

Frequently Asked Questions

Is this oil good for older diesel engines? Yes, its mineral base and CF rating provide solid protection for pre-2000 diesels, controlling soot and wear effectively.

Can I use it in my petrol car with turbo? Absolutely, the SL specification and multi-grade flow handle turbo heat and high-rev demands without breaking down.

What if I live in very hot areas? It performs well up to 100°C operating temps, but switch to a higher grade like 20W50 if you exceed 40°C ambient regularly.
