Castrol VECTON® 15W-40 CK-4/E9 is an advanced mineral heavy duty diesel engine oil that is specifically engineered to deliver longer useful oil life. It is suitable for use in high speed 4-stroke diesel engines that use a broad range of fuel qualities. It is also compatible with diesels engines fitted with exhaust gas recirculation (EGR) systems.
Castrol Vecton 15W-40 CK-4/E9 is suitable with biodiesel per OEM recommendations.
Castrol VECTON's System Pro Technology™ has an extra performance reserve that fights oil breakdown by:
- Combating oxidation and deposits
- Neutralizing harmful acids
- Controlling oil aeration
- Also adapting to increased temperatures while resisting viscosity loss through shear.
All of this means longer useful oil life, giving you the confidence in your maximum drain interval.
