Up to 75% of engine wear happens while your engine warms up. When the engine stops oils drain off critical engine parts, however Castrol MAGNATEC’s intelligent molecules don’t. They cling to the engine like a magnet providing an extra layer of protection.
Castrol MAGNATEC’s unique formulation protects from the moment you start, dramatically reducing* engine wear. Now with ultra-refined molecules, for protection you can see, hear and feel. Castrol MAGNATEC. Instant Protection From The Moment You Start.
*As tested in the industry Sequence IVA wear test
Castrol MAGNATEC 5W-30 DX is suitable for use in automotive gasoline engines where the manufacturer recommends an API SP, ILSAC GF-6 or earlier specification 5W-30 lubricant.

CASTROL MAGNATEC PROTECTS MILLIONS OF ENGINES AROUND THE WORLD.
Traffic congestion has increased significantly over the past decade. That’s annoying, but worse, it slowly damages your engine – permanently. To respond to increasingly urbanised environments, we developed Castrol MAGNATEC with patented DUALOCK technology.
Mechanics choose Castrol MAGNATEC with DUALOCK Technology to protect engines all around the world from warm-up wear and re-start wear. Castrol MAGNATEC clings like a magnet to the vulnerable metal surfaces in your engine during warm-up. The unique patented molecule in DUALOCK Technology then locks together with the other MAGNATEC molecule, forming a forcefield that provides 50% better protection from warm-up wear and re-start wear.
