Product Description

Castrol MAGNATEC Professional C3 5W-40 is a premium automotive engine oil for petrol and diesel passenger cars, including vehicles equipped with diesel particulate filters (DPF), where SAE 5W-40 and ACEA C3 performance are required. Key applications include modern European passenger cars, turbocharged and naturally aspirated engines, urban stop-start driving, frequent cold starts, and vehicles requiring a mid-SAPS ACEA C3 lubricant. Its formulation is designed to provide continuous protection during start-up and normal driving by helping the lubricant adhere to critical engine components.

Castrol MAGNATEC Professional C3 5W-40 is formulated using chemically modified base oils and proprietary performance additives. The formulation is designed to protect critical engine components against wear while helping maintain engine cleanliness under demanding driving conditions. The Australian SDS identifies the product as an automotive engine crankcase lubricant and confirms product code 467391.
