ACEA Oil Sequences 2021
The 2021 ACEA light-duty oil sequences are being published in order to address engine developments that are being driven by a combination of regulatory and performance needs, complemented by necessary test maintenance requirements.
Driving the need for this upgrade to the 2016 ACEA light-duty oil sequences
This document details the 2021 ACEA European Oil Sequences for light-duty engines, replacing the 2016 version.
ACEA members that manufacture light-duty vehicles are developing new engine powertrain systems to continue to improve fuel efficiency and deliver the higher performance expected from customers. Improving fuel economy means making use of lighter viscosity oil grades.
Today, the main light-duty engine technologies are gasoline and diesel direct injection (DI) turbocharged engines complemented with stop/start strategies, hybrid and electric technology. Consequently, ACEA members that manufacture light-duty vehicles are introducing new engine tests in two new engine oil Categories to ensure base protection and performance for modern engine hardware.
New engine oil categories
The first new Category is the High SAPS A7/B7-21 with low speed pre-ignition and wear protection for turbocharged DI gasoline engines as well as turbocharger compressor deposit (TCCD) protection for modern DI diesel engines.
The second Category is C6-21 (0W20) providing low speed pre-ignition and wear protection for turbocharged DI gasoline engines as well as diesel turbocharger compressor deposit (TCCD) protection for low SAPS class, being compatible with catalyst & GPF/DPF exhaust aftertreatment systems.
New engine tests for 2021 ACEA light-duty oil sequences
The 2021 ACEA light-duty oil sequences contains five new tests, one successor test and two engine tests are deleted, as follows:
Use of Performance Claims against the 2021 ACEA light-duty oil sequences
- New claims can be made against the 2021 oil sequences as from 1 May 2021.
- From 1 May 2022 onwards, the 2021 ACEA light-duty oil sequences are mandatory for all new claims.
ACEA Oil Sequences for heavy-duty engines
Because the heavy-duty oil sequences are not at the same stage of readiness, at this time we have decided to split the light-duty and the heavy-duty sequences into two separate documents and both will be directly linked with a General Requirements document addressing issues common to both the light-duty and heavy-duty oil sequences.
ACEA expects to publish the 2021 ACEA heavy-duty oil sequences (replacing this updated 2016 version) no earlier than June 2021.
