Purpose and Specifications

Shell Helix Ultra ECT C3 0W-30 1L is a fully synthetic engine oil designed for modern gasoline and diesel engines with emission systems like diesel particulate filters and catalysts. It flows easily at cold starts down to -35°C for quick protection and stays thick up to 150°C to shield against wear in hot conditions.

This low-friction oil cuts engine drag for up to 2.6% better fuel economy, keeps pistons 45% cleaner than industry standards, and provides three times better rust protection to extend engine life. Approved for VW 504.00/507.00, MB 229.51/229.52, and Porsche C30, it suits high-performance cars under severe driving.

When to Use / Replace?

• Use it if: Your car has modern emission controls, turbochargers, or direct injection; ideal for year-round driving in extreme hot or cold climates.
• Replace every: 15,000-30,000 km or 12 months, depending on your owner's manual—check oil level monthly to avoid top-ups thanks to its low evaporation.
• Shelf life: Up to 5 years unopened in cool, dry storage.
