Did you know that up to 75% of engine wear occurs during the first 20 minutes? Thats the length of time it takes for an engine oil to reach its optimal operating temperature. Unlike other motor oils, which drain fully into the sump when the engine is off, CASTROL GTX MAGNATEC 10W40 is a full synthetic motor oil, liquid engineered with intelligent molecules that cling to critical engine parts, forming an extra layer of protection from the moment you start.

This dramatically reduces engine wear and leaves critical engine components up to four times smoother. If you typically take multiple short trips or drive in heavy traffic, CASTROL GTX MAGNATEC 10W40 is a great way to protect your engine from wear.
