  • Active Cleansing Technology
    Up to 20% more effective at removing sludge than mineral oil.
  • Maintains viscosity level
    Maintains viscosity and stays in grade throughout the oil-change interval.
  • Long-term oxidation stability
    Resists oil degradation throughout the oil-change interval.

A cleaner, quieter gas engine

Cleaner engines can operate more efficiently. Efficient engines are likely to feel smoother and be quieter.

Shell Helix HX5 G motor oil for gasoline engines uses special Active Cleansing Technology to help engines to operate efficiently for a smoother and quieter drive. In studies carried out by an independent market research agency, a statistically significant number of respondents felt that their cars were quieter after a Shell Helix HX5 G oil change.

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 HX5 G goes on delivering its benefits throughout the oil-change interval.

Shell Helix HX5 G is specifically formulated for fuel-injection gas or gasoline engines with blow-by-gas recirculation. It meets vehicle manufacturers’ specifications.

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 HX5 G:

  1. Up to 20% more effective at removing sludge from gasoline engines than a normal mineral oil.
  2. Resists oil degradation throughout the oil-change interval.
  3. Reduces oil volatility and therefore oil consumption.
  4. 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 HX5 G exceeds these specifications: API SL/CF; ACEA A2.
