Up to 75% of engine wear happens while your engine starts and warms up. When the engine is off, a motor oil flows in the crankcase pan leaving the most relevant engine parts unprotected. Castrol Magnatec molecules cling to the engine like a magnet providing an extra layer of protection during the engine start when the risk of wear is significantly higher. Castrol Magnatec Intelligent Molecules: cling to critical engine parts when usual oil drains down; cling to the engine forming an extra layer that protects during start up and beyond; bond to metal surfaces to make engine parts more resistant to wear; are combined with synthetic technology to provide increased protection in high and low temperature applications; provide continuous protection for all driving conditions, styles and temperatures. Castrol Magnatec 5W-40 A3/B4 delivers superior performance under extreme cold start up conditions. Castrol Magnatec 5W-40 A3/B4 is specially designed and tested considering the peculiarities of Russian operation conditions. It ensures the comprehensive engine protection even in the most severe road conditions: low-temperature operation, use of Russian fuel and driving in city traffic jams.
