The intelligent molecules in Castrol GTX MAGNATEC are what set it apart from other engine oils. These ultra-refined molecular components cling to the engine throughout all driving conditions, even when the engine is off. When the engine stops, oil drains back to the sump, but the intelligent molecules in Castrol GTX MAGNATEC don’t. They cling to critical engine parts like a magnet, providing an extra layer of protection from the start and throughout warm-up. Only Castrol GTX Magnatec is uniquely formulated to provide instant protection from the moment of start.

Product Features:
  • Cling to critical engine parts when the oil drains down
  • Add a layer of protection during warm-up and beyond
  • Dramatically reduce engine wear
  • Leave critical engine parts 4X smoother
