Castrol MAGNATEC 10W-40 A3/B4 is a cutting-edge car engine oil designed to offer maximum performance in modern driving conditions. Setting out to create a solution for the stop-start driving that’s a common feature of city roads, Castrol created their MAGNATEC technology. Containing unique DUALOCK molecules, MAGNATEC oils cling to important engine parts and create a shield layer that provides ongoing protection, effective from the moment the engine starts up.

Where other engine oils will drain off elevated parts when the engine is idle, Castrol MAGNATEC oils with DUALOCK molecules act like a magnet and remain in place. And since up to 75% of engine wear occurs while the engine warms up, Castrol’s MAGNATEC oil formulation can reduce wear by up to 50%, extending the health of your engine. Suitable for use in both petrol and diesel engines, Castrol MAGNATEC 10W-40 A3/B4 is the perfect choice for drivers seeking an engine oil that offers the ultimate protection in stop-start driving conditions.
