  • Better engine performance
    Shell Helix HX7 removes up to 39% more sludge than Shell Helix HX5.
  • Longer protection thanks to enhanced oxidisation resistance
    Shell Helix HX7 provides up to 24% more protection than Shell Helix HX5.

Active cleansing and protection for your car

Shell Helix HX7 motor oil uses special active cleansing agents to help engines operate efficiently. In studies by an independent agency, drivers said that their cars felt more responsive after a Shell Helix HX7 oil change.

The oil in a clean engine can flow quickly to where it is needed, ensuring the engine is better protected.

The excellent cleaning power and shear and oxidation stability of Shell Helix HX7 mean that it goes on delivering its benefits from one oil change to the next.

Shell Helix HX7 is specifically formulated for fuel-injection gasoline engines that are fitted with catalytic converters and blow-by-gas recirculation. The oil meets vehicle manufacturers’ specifications and severe-service applications, and has formulations for different fuels, engines and environmental conditions.

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 HX7:

  1. Up to twice as effective at removing sludge as a normal mineral oil.
  2. It offers up to 19% more protection than other synthetic leading brands tested.
  3. Greater fuel efficiency.
  4. Maintains viscosity and stays in grade throughout the oil-change interval.
  5. Reduces oil volatility and therefore oil consumption and the need for top-up.
  6. Smoother, quieter drive.

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 HX7 exceeds these specifications:

  • API SN/CF
  • ACEA A3/B3/B4
  • JASO SG+
  • MB approval 229.1
  • VW 5025 00/505 00
  • PSA D Level III
