  • Active Cleansing Technology
    Works harder to protect than ordinary motor oils by continuously preventing soot build-up.
  • Formulated with special base oils
    Reduces friction to lessen fuel consumption and exhaust emissions.
  • Good oxidation stability
    Resists oil degradation throughout the oil-change interval.

Cleans to help diesel engines operate efficiently

Ordinary oils can have high internal friction that affects engine efficiency. Cleaner engines can operate more efficiently. Efficient engines are likely to feel smoother and be quieter.

Shell Helix Diesel HX5 E motor oil contains special Active Cleansing Technology and helps diesel engines to operate efficiently for a smoother and quieter drive. Soot from diesel combustion can increase an oil’s viscosity, which forces the engine to work harder. Shell Helix Diesel HX5 E removes soot from surfaces without a large change in its viscosity. The oil cleans the engine and continues to flow quickly, so that the engine operates efficiently and smoothly.

The oil in a clean engine can flow more quickly to where it is needed and has improved access to surfaces, so that the engine is better protected. Shell Helix Diesel HX5 E goes on delivering its benefits throughout the oil-change interval.

Shell Helix Diesel HX5 E is specifically formulated for naturally aspirated or turbocharged indirect-injection diesel engines fitted with blow-by-gas recirculation.

Shell Helix tests

To clean and protect an engine, the oil must continue to perform until it is removed when the car is serviced. With some manufacturers recommending longer service intervals, an oil’s ability to stay fit is even more important. Throughout the oil’s life, it has to disperse more and more dirt – keeping it locked away and preventing it from being redeposited in the engine.

Our scientists perform a variety of tests that measure the ability of Shell Helix oils to resist breakdown and disperse dirt. We also test our competitors’ oils, so that we can benchmark our lubricants and demonstrate the benefits of using Shell Helix oils.

Why you should use Shell Helix Diesel HX5 E:

  1. Reduced friction to help improve fuel consumption.
  2. Up to 20% more effective at removing sludge from gasoline engines than a normal mineral oil.
  3. Resists oil degradation throughout the oil-change interval.
  4. Reduces oil volatility and therefore oil consumption.
  5. Smoother, quieter drive.
  6. Greater fuel efficiency.

Specifications and approvals

Because lubricants vary in quality, universal criteria are used to describe oil performance and usage. Shell Helix motor oils not only meet these increasingly demanding international specifications but usually surpass them. Shell Helix Diesel HX5 E exceeds these specifications: API CF; ACEA A2/B2.
