ACEA E11-21
ACEA E11-21 oils are mid SAPS1 Super High Performance (SHPD) lubricants for use in mid drain applications.
ACEA recommend ACEA E11-21 for use in vehicles fitted with advanced exhaust aftertreatment systems for the reduction of particulate matter (DPFs) and the oxides of nitrogen (EGR and/or SCR) in combination with low sulphur diesel fuel.
ACEA E11-21 replaces ACEA E9-16 in the latest update of the sequences.
The main physical and chemical requirements for ACEA E11-21 are shown below:
| Requirement | Method | Unit | Limit |
| HTHS viscosity | CEC L-36-A-90 | cP | ≥ 3.5 |
| Sulphated Ash | ASTM D874 | %wt | ≤ 1.0 |
| Phosphorus | ASTM D5185 | %wt | ≤ 0.12 |
| Sulphur | ASTM D5185 | %wt | ≤ 0.4 |
| Evaporation loss (NOACK) | CEC L-40-A-93 | % | ≤ 13 |
| Total Base Number | ASTM D2896 | mgKOH/g | ≥ 7 |
The requirements of the Cummins ISM test places emphasis on enhanced soot related wear control for ACEA E11-21 in comparison to other ACEA Categories.
ACEA E11-21 is typically grouped with a range of other approvals. Some examples of approvals that can be targeted in conjunction with E11-21 are API CK-4, MB228.31, MAN M3775, MTU Type 2, Volvo VDS-4.5 & Deutz DQC III-18 LA.
Typically, OEM approvals outlined by Daimler, MAN, MTU and Deutz will build on top of an ACEA E11-21 baseline with additional performance requirements in areas such as wear protection and protection against oxidation.
Note 1 : SAPS refers to Sulphated Ash, Phosphorus and Sulphur, the levels of which are often restricted in the latest performance specifications.
Changes
ACEA E11-21 introduces additional requirements in comparison to ACEA E9-16.
The changes beyond the ACEA E9-16 category are summarized below: :
| Test | ACEA E11-21 vs ACEA E9-16 |
| ASTM D8048 (Volvo T-13) | Added with limits to align with API CK-4. Increased oxidation performance requirements vs ACEA E9-16 |
| ASTM D8047 (COAT) | Introduced into E11-21 at API CK-4 level |
| CEC L-101-08 (OM501LA) | ??? |
| CEC L-109-16 (OM646BIO) | Increase of 2 merit points |
| CEC L-112 (Seals) | Limits updated to align with latest OEM specifications |
| ASTM D892 (Foaming) | Added to E11-21 to align with ACEA E4-21, E7-21 & E8-21 |
| ASTM 6443 (Chlorine) | Chlorine now to be reported |

ACEA E11-21 and ACEA E9-16
This comparison illustrates how both sequences are expected to provide similar performance in most areas. However, ACEA E11-21 is expected to provide a higher level of performance in terms of protection against oxidation.
