  • Active Cleansing Technology
    Excellent engine protection against the build-up of deposits.
  • Low viscosity level
    Greater fuel efficiency compared with a 15W-40 mineral oil.
  • Good oxidation stability
    Resists oil degradation throughout the oil-change interval.

Designed to make Japanese engines more efficient

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

Shell Helix HX5 AJ is designed specifically for Japanese engines. It uses special Active Cleansing Technology to help engines to operate efficiently.

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

Shell Helix HX5 AJ is specifically formulated for fuel-injection gasoline engines with blow-by-gas recirculation. It is also suitable 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 HX5 AJ:

  1. Provides excellent engine protection by continuously helping to prevent deposit build-up.
  2. Resists oil degradation throughout the oil-change interval.
  3. Reduces oil volatility and therefore oil consumption.
  4. Greater fuel efficiency compared with a 15W-40 mineral oil.
  5. Longer catalyst life.

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 AJ exceeds these specifications: API SL/CF, ILSAC GF-3.
