Castrol Vecton Long Drain 10W-40 E6/E9 is a full synthetic, low SAPS heavy-duty diesel engine oil designed for extended drain intervals up to 100,000 km to 120,000 km in modern European commercial vehicles.
Modern machinery use new technologies to make as much as 30% higher torque, but that also brings higher engine temperatures and pressures. This can lead to accelerated oxidation and oil thickening, increased build-up of deposits, and rapid depletion of the oil’s acid-controlling reserves. All of which pushes the oil closer to breakdown and reduces useful oil life.
Castrol has developed VECTON with new System Pro Technology™, which has an extra performance reserve that fights oil breakdown by helping to control oxidation, reduce deposits, neutralise harmful acids and also adapt to higher temperatures, maintaining viscosity. That means longer useful oil life, giving you confidence in your maximum drain interval.
