Advantages
Castrol VECTON 15W-40 CK-4/E9 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.
All Castrol VECTON products are also certified CO2-neutral according to the internationally applicable PAS 2060 standard, through a program that invests in carbon-reduction projects around the world.
Modern trucks use new technologies resulting in different torq requirements which means higher engine temperatures and pressures. This punishes the oil, pushing it closer to breakdown, and reducing its useful life and ability to extend drain intervals. 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.
