Testing confirms that up to 75% of engine wear occurs during the first 20 minutes of warm up. Normally, when your engine stops, oil drains off critical engine parts. The intelligent molecules in Castrol® GTX MAGNATEC® don't drain the same way, so you get an extra layer of protection during warm up, when your engine needs it most. This dramatically reduces engine wear and keeps critical parts up to 4X smoother.*
