Purpose and Specifications

Shell Helix Ultra Diesel 5W-40 1L is a fully synthetic engine oil designed for high-performance diesel engines, including turbocharged and direct injection types. Its 5W-40 viscosity flows easily at cold starts down to -39°C for quick protection, while staying thick up to high operating temps over 150°C to shield parts during hard driving.

This oil uses Shell's PurePlus Technology from natural gas for superior cleansing, locking away dirt and sludge to keep your engine factory clean. It cuts engine noise for a quieter ride, boosts fuel economy through low friction, and reduces wear for longer engine life. Approved for BMW LL-01, Mercedes 229.5, VW 505.00, and more, it supports extended drain intervals up to 15,000-30,000 km or 12 months per manufacturer guidelines.

When to Use / Replace?

Use in modern diesel cars with turbochargers, EGR, or common rail systems for daily commutes, city stop-go, or highway runs. Ideal if you face cold winters or hot summers. Replace every 15,000-30,000 km or annually, or sooner if towing/heavy loads. Shelf life is 5 years unopened in cool, dry storage.

• Cold starts: Flows fast at -39°C, prevents dry wear.
• Hot conditions: Maintains protection at high revs and temps.
