Description
CASTROL MAGNATEC 10W-40 SYNTHETIC BASE ENGINE OIL 4L is one of the world’s most trusted motor oils, specifically engineered to protect your engine during the critical warm-up period. Did you know that up to 75% of engine wear happens while your engine is warming up? When the engine stops, ordinary oils drain off critical engine parts, but CASTROL MAGNATEC 10W-40 SYNTHETIC BASE ENGINE OIL 4L is different. Its intelligent molecules cling to the engine like a magnet, providing an extra layer of protection from the moment you start your car.
