Purpose and Specifications

Shell Helix Ultra Diesel 5W-40 4L 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. Perfect for city stop-go traffic, high revs, or extreme climates.

• Maximum clean-up: Prevents soot and deposits buildup
• Long protection: Supports up to 20,000 km or 12 months between changes per manufacturer intervals
• Low consumption: Less need for top-ups
• Shelf life: 5 years unopened in cool, dry storage
