ACEA E11-22
ACEA E11-22 oils are mid SAPS1 Super High Performance (SHPD) lubricants for use in mid drain applications.
ACEA recommend ACEA E11-22 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 E11-22 replaces ACEA E9-16 in the latest update of the sequences.
The main physical and chemical requirements for ACEA E11-22 are shown below:
| Requirement | Method | Unit | Limit |
| HTHS viscosity | CEC L-36-90 | mPa.s | ≥ 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-40-93 | % | ≤ 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 E11-22 in comparison to other ACEA Categories.
ACEA E11-22 is typically grouped with a range of other approvals. Some examples of approvals that can be targeted in conjunction with E11-22 are API CK-4, Daimler MB-approval MB228.31, MAN M3775, MTU Type 2, Volvo VDS-4.5 & Deutz DQC III-18 LA.
Typically, OEM approvals outlined by Daimler, MAN, MTU, Volvo and Deutz will build on top of an ACEA E11-22 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 E11-22 introduces additional requirements in comparison to ACEA E9-16.
The changes beyond the ACEA E9-16 category are summarized below:
| Test | ACEA E11-22 vs ACEA E9-16 |
| CEC L-101-09 (OM501LA) | Option included to use OM501LA data in place of Caterpillar C13 test if available |
| ASTM D8048 (Volvo T-13) | Introduced into E11-22 at API CK-4 level. Added to increase oxidation performance requirements vs ACEA E9-16 |
| ASTM D8047 (COAT) | Introduced into E11-22 at API CK-4 level |
| ASTM D7549 (Caterpillar C13) | Caterpillar C13 added, OM501LA data can be used to E9-16 requirements to support E11-22 |
| ASTM D7468 (Cummins ISM) | Limits updated to align with API CK-4 |
| CEC L-104-16 (OM646BIO) | Increase of 2 merit points |
| ASTM D6443 (Chlorine) | Chlorine now to be reported |
| CEC L-112-16 (Seals) | Limits updated to align with latest OEM specifications |
| ASTM D6082 (Foaming) | D6082 foam has been added |
