ACEA Oil Sequences

The ACEA 2016 European Oil Sequences for Service-fill Oils comprise 3 sets (classes) of sequences: one for Gasoline and Light Duty Diesel engines; one specifically for Gasoline and Light Duty Diesel engines with after treatment devices and one for Heavy Duty Diesel engines. Within each of these sets there are categories which reflect different performance requirements – three (A3/B3, A3/B4 & A5/B5) for Gasoline and Light Duty Diesel Engines, five (C1, C2, C3, C4, C5) specifically for Engines with After Treatment Devices, and four (E4, E6, E7, E9) for Heavy Duty Diesel Engines.

The ACEA Oil Sequences define the minimum quality level of an engine oil for self-certification to EELQMS (European Engine Lubricants Quality Management System) and presentation to ACEA members. Individual member companies may indicate performance parameters other than those covered by the tests shown or even more stringent limits.

ACEA Sequences always indicate a year. The year numbers for ACEA Sequence is intended only for industry use and indicates the year of implementation of that severity level for the particular category. A new year number will indicate, for example, that a new test, parameter or limit has been incorporated in the category to meet new / upgraded performance requirements whilst remaining compatible with existing applications. An update must always satisfy the applications of the previous issue. If this is not the case, then a new category is required.
