Purpose and Specifications

Castrol Vecton Long Drain 10W-40 E6/E9 5L is a full synthetic heavy-duty diesel engine oil built for trucks and buses with Euro 4 to Euro 6 engines. It flows smoothly at cold starts down to -25°C and stays thick under extreme heat up to 150°C, protecting your engine during long hauls. This premium low-SAPS formula cuts ash buildup in diesel particulate filters (DPF), fights wear on pistons and critical parts, neutralizes acids, and handles soot for up to 120,000 km drain intervals or 2 years, depending on your truck's manual and conditions.

• Approved for MAN, Mercedes-Benz, Volvo, Deutz, Renault, DAF Euro VI, Cummins, Caterpillar, and more
• 45% extra performance reserve fights oil breakdown in high-torque engines
• Ideal for EGR, SCR, and DPF systems with low-sulfur fuel

When to Use / Replace?

Use this oil in modern heavy-duty diesels for maximum drain times - up to 100,000-120,000 km per OEM specs like MAN or Mercedes. Replace when your truck's onboard diagnostics signal it, typically every 12-24 months or at the manufacturer's interval, whichever comes first. Perfect for severe conditions like high loads, dusty roads, or stop-go city driving where engines hit peak temps over 130°C. Shelf life is 5 years unopened in cool, dry storage.

FAQ

Can I use it for extended drains? Yes, engineered for up to 120,000 km in approved engines, but always check your owner's manual and fuel quality.

Is it safe for DPF-equipped trucks? Absolutely - low SAPS design prevents filter clogging while protecting against deposits and wear.

What if my truck is older? Works great in Euro 1-6 diesels, on-road or off-road, boosting protection beyond standard oils.
