Smart Molecules. Non-Stop Engine Protection. Ultimate Wear Defense.

Castrol MAGNATEC 5W-30 is engineered to meet the challenges of modern stop-start and city driving.
Up to 75% of engine wear occurs during ignition and low-speed driving — when friction peaks and vital components are most vulnerable. MAGNATEC’s unique intelligent molecules cling like magnets to critical engine parts, providing instant protection from the moment you start.

Whether it’s the daily commute, a weekend trip, or stop-and-go traffic, Castrol MAGNATEC ensures your engine stays protected and efficient with 50% better wear protection compared to industry standards*.

Key Benefits

Magnetic Protection: Advanced molecules cling, lock, and protect engine parts for continuous lubrication.

Reduced Engine Wear: Offers 50% better wear protection* across the valvetrain, pistons, bearings, and timing chain.

Hybrid-Ready Formula: Meets Castrol HYSPEC standards for modern hybrid engines — delivering exceptional performance across contaminants, intermittency, and system efficiency**.

Smoother Operation: Minimizes timing chain elongation and maintains precise engine synchronization.

Full Synthetic Performance: Designed for long life, clean operation, and enhanced efficiency.

Applications

Ideal for gasoline and hybrid vehicles requiring API SP, ILSAC GF-6, or earlier 5W-30 specifications.
Suitable for most modern passenger cars that demand superior protection in city traffic and frequent-start environments.

Technology & Protection

Castrol’s MAGNATEC intelligent molecules act like self-adjusting magnets —
forming a durable protective layer that stays attached even after the engine stops.
This unique behavior drastically reduces metal-to-metal contact during start-up and stop-go driving cycles, keeping your engine running smoother, cleaner, and longer.
