Description Castrol MAGNATEC has been developed to meet the unique demands of modern driving. 75% of engine wear can happen when we start the ignition. And acceleration, slowing down, and idling journeys in city driving only increase this strain. That means every congested commute, weekend getaway, and shopping trip may increase engine wear.
Advantages Castrol MAGNATEC clings, locks, and protects to deliver 50% better engine wear protection*. Helping to safeguard your engine’s vital components by: Forming a resistive barrier between metal contact points in the valvetrain Managing abrasive piston deposits, guarding against cylinder liner wear Maintaining timing chain tension and engine synchronicity by minimising chain damage and elongation
Storage All packages should be stored under cover. Where outside storage is unavoidable drums should be laid horizontally to avoid the possible ingress of water and damage to drum markings. Products should not be stored above 60°C, exposed to hot sun or freezing conditions.
