CASTROL MAGNATEC 10W-40 A/B
Castrol MAGNATEC 10W-40 A/B-grade engine oil is a semi-synthetic lubricant with unique DUALOCK molecules that deliver robust performance across a wide temperature range under everyday driving conditions. The product is designed for modern automotive gasoline and diesel engines where the manufacturer recommends an engine oil that meets the ACEA A3/B4 or API SP standards in a 10W-40 viscosity class.
The proprietary DUALOCK technology used in the MAGNATEC range features molecules that cling to critical engine parts and surfaces, and lock together to form a protective film from the very moment the ignition is turned. Castrol MAGNATEC 10W-40 A/B’s extensive molecular protection dramatically reduces stop-start wear and maintains vital components before the engine warms up.
If you need a product for a car or motorcycle engine that meets strict specifications and standards, Castrol MAGNATEC 10W-40 A/B may be the engine oil you need.
