Description:

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) system.

Advantages:

Castrol VECTON® 15W-40 CI-4/E7 with System Pro Technology™ delivers up to 45% extra performance reserve* that fights oil breakdown and also adapts to higher temperatures for longer useful oil life,  giving you confidence in your maximum drain interval. 

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.  Castrol VECTON® 15W-40 CI-4/E7's System Pro Technology™ formulated with  extra performance reserve fights oil breakdown by:

• Controlling oxidation and deposits

• Neutralizing 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.  

*Compared to API and ACEA industry requirements and based on tests conducted on 81% of the Castrol VECTON range by volume using 12 months sales up to March 2017.
