Castrol MAGNATEC 10W-40 A is a multi-grade engine oil featuring DUALOCK / intelligent molecules that cling to critical engine parts and lock together to form a protective force field, reducing warm-up and stop-start wear by up to 50%.
Key Features & Specifications
• Viscosity Grade: SAE 10W-40 (flows well during cold starts and maintains a strong protective film at high operating temperatures).
• Technology: Intelligent/DUALOCK molecules that adhere to metal surfaces rather than draining back into the oil pan when the engine is turned off, providing instant protection the moment you start the ignition.
• Industry Standards / Specifications:
• API SP / SN / CF
• ACEA A3/B4
• Vehicle Compatibility: Suitable for use in automotive petrol and diesel engines (without diesel particulate filters / DPF) where the manufacturer recommends a 10W-40 oil matching the above specifications. Frequently chosen for older engines, high-mileage cars, or vehicles operating in warm climates or heavy stop-start urban traffic.
• Approvals & OEM Suitability: Often aligns with requirements such as VW 501 01 / 505 00 and MB-Approval 229.1 / 229.3 depending on the specific regional sub-variant
