Castrol Vecton Long Drain 5w-20 SLD5 - Longer Useful Oil Life

DESCRIPTION

CASTROL VECTON LONG DRAIN 5W-20 SLD5 has been developed to meet the latest MAN and Scania requirements for heavy-duty diesel engines using advanced exhaust after-treatment systems such as diesel particulate filters (DPFs) and in combination with low-sulphur diesel fuel. An advanced full synthetic heavy-duty diesel engine oil engineered to deliver longer useful oil life and additional fuel savings*

Modern trucks make as much as 30% higher torque. This punishes the oil, pushing it closer to breakdown, reducing its useful life. VECTON LONG DRAIN 5W-20 SLD5’s System Pro Technology is formulated with extra performance reserve to fight oil breakdown.

APPLICATIONS

CASTROL VECTON LONG DRAIN 5W-20 SLD5 has been developed to meet the latest MAN and Scania requirements for heavy-duty diesel engines using advanced exhaust after-treatment systems such as diesel particulate filters (DPFs) and in combination with low-sulphur diesel fuel.

For modern heavy-duty diesel engines in trucks, buses, and commercial vehicles.
Compatible with engines equipped with DPF, EGR, and SCR NOx systems.
Suitable for fleets requiring low-viscosity oils for improved fuel efficiency and reduced CO₂ emissions.
Recommended for use with low-sulphur diesel fuel.

ADVANTAGES

Why Choose Castrol VECTON Long Drain 5W-20 SLD5?

Castrol VECTON Long Drain 5W-20 SLD5 represents the next generation of low-viscosity heavy-duty lubricants, combining energy efficiency, durability, and protection.
It helps fleets reduce operating costs, extend service intervals, and achieve sustainability goals without compromising performance or reliability.

With System Pro Technology™, you get an oil that’s engineered to handle the demands of today’s high-output diesel engines—so you can stay on the road longer and protect your investment.

Modern trucks use new technologies to make as much as 30% higher torque, but that also brings higher engine temperatures and pressures. This punishes the oil, pushing it closer to breakdown, reducing its useful life. VECTON LONG DRAIN 5W-20 SLD5’s System Pro Technology™, formulated with extra performance reserve, fights oil breakdown
by:

Controlling oxidation and deposits
Neutralising harmful acids
Maintaining viscosity

System Pro Technology™ also adapts to increased temperatures, resisting viscosity loss through thermal and mechanical shear. All of this means longer useful oil life, giving you the confidence in your maximum drain interval.

* When compared to conventional 15W40s in laboratory engine testing.
