The ATIEL Code of Practice is accepted industry-wide as best practice for the development and manufacture of engine oils conforming to European ACEA (Association of European Automotive Manufacturers) standards.

It has helped to set standards and quality guarantees for lubricants made or marketed by oil companies that adhere to its guidelines. It provides a benchmark for auditing the development and production of lubricants and ensuring the validity of performance claims made for them.

The ATIEL Code of Practice is updated every one to two years to reflect changes in technical performance specifications, engine testing etc. To ensure that you are aware of, and using, the latest version you can sign up to receive automatic notification of changes or updates to the Code of Practice by e-mail (top right).
