Castrol VECTON with System Pro Technology™ is a range of advanced diesel engine oils formulated with extra performance reserve for longer useful oil life.
Castrol VECTON is specifically engineered to deliver longer oil life and enable longer service intervals—even under severe operating conditions. This exceptional diesel oil conforms to the latest engine oil specifications and is available in three viscosity grades.
Castrol VECTON delivers a 45% extra performance reserve* that fights oil breakdown by helping to control oxidation, reduce deposits, and neutralize harmful acids. It also adapts to higher temperatures, which helps to maintain viscosity.
Castrol VECTON SAE 10W-30 FA-4 is a heavy-duty diesel engine oil that is engineered specifically for fuel economy in select 2017 and beyond model year diesel engines. It is targeted exclusively at today’s low-emission, low-fuel-consumption trucks and buses where API FA-4 is required by OEMs.
Pumping oil around the engine creates drag, which saps engine power and increases the consumption of diesel fuel. Castrol VECTON 10W-30 FA-4 with unique SYSTEM PRO TECHNOLOGY™ has lower viscosity under high-temperature and high-shear forces to reduce drag, which improves the productivity of the engine and enhances fuel economy up to 1.5%.†
It offers drain intervals of up to 60,000 miles or 750 hours.^
