Purpose and Specifications

Castrol 5W30 Magnatec DX 4L is a premium full synthetic engine oil that clings like a magnet to critical engine parts, delivering instant protection from the moment you start your car. Its intelligent molecules form an extra layer on metal surfaces like the valvetrain, pistons, bearings, and timing chain, cutting engine wear by up to 50% during cold starts and stop/start traffic.

The 5W30 viscosity flows easily at low temperatures down to -30°C for quick startups and stays thick up to 150°C to protect in hot conditions. It meets top specs including API SP, GM dexos1 Gen2/Gen3, and ILSAC GF5, making it perfect for modern gasoline engines in cars from Ford, GM, Kia, Nissan, and more.

• 50% better wear protection on cold starts and restarts versus industry standards
• Handles all driving: city traffic, highways, extreme temps
• 4-liter pack for full oil changes in most sedans and SUVs
