ATIEL, the technical association for the European lubricants industry, this week published an updated version of its Code of Practice, which sets guidelines for the development of ACEA automotive engine oil sequences for the European Automobile Manufacturers’ Association. Issue 22 of the code includes the ACEA 2021 update to the association’s light-duty engine oil sequences, which had their commercial launch in May. Issue 21 is still available on ATIEL’s website for reference for valid claims against the 2016 sequences. Lube marketers are permitted to promote products as meeting the 2016 light-duty sequences until April of next year. The organization’s codes of practice are available for free download here.
