Under the European Engine Lubricant Quality Management System (EELQMS), lubricant marketers or manufacturers making claims against the ACEA Oil Sequences are required by ACEA to submit a Letter of Conformance to ATIEL. Submission of a Letter of Conformance implies a commitment to develop and manufacture engine lubricants in accordance with the guidelines described in the ATIEL Code of Practice. Currently, some 80 lubricant companies in Europe have signed a Letter of Conformance.
In addition, ACEA members have confirmed in writing that to the extent that they market lubricants under their own brands, their suppliers have all signed the Letter of Conformance, whether or not the ACEA members make claims against ACEA sequences for the lubricants marketed under their label.
The Marketers' Letter of Conformance is shown in Appendix E of the Code of Practice and the template can be downloaded below, along with a list of signatories. Letters of Conformance are normally renewed every two years in line with updates to the Code of Practice – see renewal process document below.
Base Stock Manufacturers
Base stock manufacturers, including partner groups, wishing to declare that they manufacture base stocks in accordance with the ATIEL Code of Practice (Base Stock Quality Assurance guidelines described in Appendix B) may also sign a Letter of Conformance.
The Base Stock Manufacturers’ Letter of Conformance is shown in Appendix E of the Code of Practice and the template can be downloaded below.
