Purpose and Specifications

Castrol Magnatec 5W-30 S1 1L engine oil delivers instant protection from the moment you start your engine. Its intelligent molecules cling like a magnet to critical parts such as the valvetrain, pistons, bearings, and timing chain, forming a self-healing layer that cuts engine wear by up to 50% during startup when up to 75% of wear happens.

This fully synthetic premium oil flows easily in cold temps down to -30°C for quick startup protection and stays stable in high heat over 100°C, keeping your engine clean, preventing deposits, and boosting efficiency. It meets API SN and ACEA C2 specs, plus Fiat 9.55535-S1, making it perfect for gasoline, diesel, hybrid, and Fiat vehicles.
