About the EELQMS

The European Engine Lubricants Quality Management System (EELQMS) is a quality system for automotive engine lubricants that are designed to meet the minimum performance requirements of leading European vehicle manufacturers.

These requirements are set out in specifications established by ACEA (the European Automobile Manufacturers Association), which represents leading car, van, truck and bus makers, in its European Oil Sequences.

Lubricants marketers that meet the requirements of one of the ACEA performance specifications (ie Oil Sequences) can include an appropriate performance claim on their product packaging (right). For these claims to be valid, however, the lubricant must have been developed in accordance with the  guidelines outlined in the EELQMS.

The EELQMS is a voluntary quality system but is THE ONLY system that can be used to support an ACEA performance claim. By providing a detailed step-by-step auditable process to follow, it provides reassurance to OEMs, workshops and consumers that engine lubricants on the market meet the performance claims being made for them.

The EELQMS was established in 1996 by the three key engine lubricants industry stakeholders: ACEA representing vehicle OEMs; ATIEL representing lubricant formulators and marketers; and ATC (The Technical Committee of Petroleum Additive Manufacturers in Europe) representing engine lubricant additive package developers and producers.

It embraces various standards, test methods and procedures and Codes of Practice as well as the ACEA Oil Sequences requirements. Its guidelines cover all aspects of the lubricant development from formulation and modification, through engine and bench testing procedures, to performance validation, blending and marketing (see below)They also include requirements for documentation of lubricant development and independent auditing of the process.

In tandem with the creation of EELQMS, ATIEL and ATC developed their Codes of Practice, which provide the technical guidelines to support the quality system.

Since its introduction the EELQMS has led to:

  • more clearly defined specifications for service-fill engine lubricants
  • new test procedures with better repeatability, reproducibility and discrimination
  • consistent higher quality lubricants in the market

The ATIEL Code of Practice is a key element of the EELQMS, providing many of the technical guidelines behind lubricant formulation modification including alterations to the viscosity grade and use of different types or volume of base oils.
