  • Low-SAPS oil for emission system protection
    Provides long life for diesel engines with diesel particulate filters and three-way catalyst systems.
  • Improved fuel efficiency
    Up to 2.5% greater fuel efficiency compared with a 15W-40 oil.
  • Active Cleansing Technology
    Works harder to protect than mineral oils by continuously preventing soot build-up.

Specially formulated for your Japanese diesel engine

Cleaner engines can operate more efficiently. Efficient engines are likely to be more responsive.

Shell Helix Diesel HX7 AJ-L motor oil uses special active cleansing agents 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 Diesel HX7 AJ-L is specifically formulated for all Japanese light-duty diesel engines, including those with diesel particulate filters. It is approved by all Japanese manufacturers for normal and extended service use.

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 HX7 AJ-L:

Low-SAPS formula provides long life for diesel engines fitted with diesel particulate filters and three-way catalyst systems.

Works harder to protect than conventional mineral oils by continuously preventing soot deposits from building up on engine surfaces.

High levels of antioxidant give excellent oxidation protection.

Up to 2.5% greater fuel efficiency compared with a 15W-40 oil.

Maintains viscosity and stays in grade throughout the oil-drain interval.

Reduces oil volatility and therefore oil consumption and the need for top-up.

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 AJ-L exceeds these specifications: ACEA B1; JASO DL-1.
