Castrol Vecton Long Drain 10w-30 E6/E9

Castrol VECTON Long Drain 10W-30 E6/E9 is an advanced part synthetic heavy-duty diesel engine oil that is specifically engineered to deliver longer useful oil life. It is suitable for highly rated diesel engines meeting Euro I to Euro VI emission requirements. It is suitable for engines with or without particulate filters, for most EGR engines and most engines fitted with SCR NOx reduction systems. It is strongly recommended for engines fitted with particulate filters and is designed for use in combination with low-sulphur diesel fuel.

The Castrol Vecton Range – new simplified, consolidation-friendly 3-tier system explained: 

Modern trucks generate up to 30% more torque due to advanced technologies, but this also raises engine temperatures and pressures. These conditions accelerate oil oxidation and thickening, increase deposit formation, deplete acid-controlling reserves—ultimately pushing the oil closer to breakdown, reducing the useful life of the oil.
Castrol VECTON helps to control oxidation, reduce deposits, neutralise harmful acids, and adapts to higher temperatures, maintaining viscosity. Castrol VECTON offers 3 product ranges:

CASTROL VECTON LONG DRAIN

Ultimate Range: Offering our Long Drain and OEM-aligned products helps deliver maximum levels of protection and performance for the latest generation of trucks, to deliver maximum drain intervals3 and fuel savings1. VECTON Long Drain with System Pro Technology™ is tested for extended drains up to 120,000 kms2. Utilising System Pro Technology™, Castrol VECTON Long Drain delivers up to 45% extra performance reserve1 for longer useful oil life, giving you confidence in your maximum drain interval.

CASTROL VECTON PLUS

Enhanced: Offering our Plus product range helps to deliver enhanced levels of protection and longer useful oil life for a wide range of engine technologies, to deliver reliable fleet performance. Offered with System Pro Technology™, formulated with extra performance reserve3, fights oil breakdown by controlling oxidation and deposits, neutralising harmful acids and maintaining viscosity. System Pro Technology™ adapts to increased temperatures, resisting viscosity loss through thermal and mechanical shear.

CASTROL VECTON MULTI

Essential: Offering our Multi Range of Suitable for Use products helps deliver trusted Castrol protection and performance in a wide range of engine technologies, for older fleets looking for a reliable, value-first option. Castrol VECTON Multi helps to keep the engine clean by preventing oil thickening and deposit build-up in critical engine parts, to help deliver reliable engine performance

• Heavy-duty diesel engines in trucks, buses, and commercial vehicles meeting Euro I to Euro VI emission standards.

• Engines with or without particulate filters (DPF), most EGR-equipped engines, and engines fitted with SCR NOx reduction systems.

• Ideal for operations requiring extended oil drains, fuel efficiency, and reliable engine protection, especially with low-sulphur diesel fuel.

Why Choose Castrol VECTON Long Drain 10W-30 E6/E9?

Castrol VECTON Long Drain 10W-30 E6/E9 combines advanced part synthetic formulation with System Pro Technology™ to deliver longer oil life, superior engine protection, and operational reliability.

It is engineered to meet the demands of modern high-torque engines, reduce maintenance intervals, and provide fuel-efficient, environmentally responsible performance for commercial vehicle fleets.

Castrol Vecton Long Drain products deliver up to 45% extra performance reserve, giving you confidence in your maximum drain interval.

All Castrol VECTON products are certified CO2 neutral according to the internationally applicable PAS2060 standard. Modern trucks use new technologies to make as much as 30% higher torque, but that also means higher engine temperatures and pressures. This punishes the oil, pushing it closer to breakdown, and reducing its useful life, and
ability to extend drains. Castrol VECTON Long Drain’s System Pro Technology has been proven in field testing to safely extend drain intervals. Formulated with up to 45% extra performance reserve, System Pro technology TM fights oil breakdown by:

1. Combating oxidation and deposits
2. Neutralising harmful acids
3. Controlling oil aeration
4. Adapting to increased temperatures, resisting viscosity loss through shear.

All of this means longer useful oil life, giving you the confidence in your maximum drain interval, is approved by MAN for oil drain up to 120,000km, in accordance with their specifications. Actual oil drain depends on engine type, operating conditions, service history, OBD and fuel quality. Always consult your manufacturer’s handbook.
