ACEA E7-22
ACEA E7-22 oils are Super High Performance Diesel (SHPD) lubricants for use in mid-drain applications.
ACEA E7-22 contains many elements of the North American API CI-4 specification. ACEA E7 is the minimum performance requirement for heavy duty applications.
The main physical and chemical requirements for ACEA E7-22 are shown below:
| Requirement | Method | Unit | Limit |
| HTHS viscosity | CEC L-36-90 | mPa.s | ≥ 3.5 |
| Sulphated Ash | ASTM D874 | %wt | ≤ 2.0 |
| Phosphorus | ASTM D5185 | %wt | N/A |
| Sulphur | ASTM D5185 | %wt | N/A |
| Evaporation loss (NOACK) | CEC L-40-93 | % | ≤ 13 |
| Total Base Number | ASTM D2896 | mgKOH/g | ≥ 9 |
ACEA E7-22 is typically grouped with a range of other approvals which may vary depending on the viscosity grade. Some examples of approvals that can be targeted in conjunction with ACEA E7-22 are Daimler MB-Approval 228.3, MAN M3275, Volvo VDS-3, Renault RLD-2, MACK EO-N & EO-M Plus, Caterpillar ECF-2, MTU Oil Category 2 and Deutz DQC III-18.
Many of the OEM approvals listed above build on top of an ACEA E7-22 baseline with additional performance requirements in areas such as wear protection and deposit control.
Changes
A number of changes to the requirements for ACEA E7-22 have been introduced in the ACEA 2022 issue of the oil sequences.
The changes for ACEA E7-22 are summarized below:
| Test | ACEA E7-22 vs ACEA E7-16 |
| CEC L-101-09 (OM501LA) | Option included to use OM501LA data in place of Caterpillar 1N test if available |
| ASTM D6750 (Caterpillar 1N) | Caterpillar 1N added as long-term replacement options for the OM501LA. OM501LA data can still be used to support ACEA E7-22 |
| ASTM D6443 (Chlorine) | Chlorine now to be reported |
| CEC L-112-16 (Seals) | Limits updated to align with latest OEM specifications |
| ASTM D892 (Foaming) | Sequence II limit updated to align with latest OEM specifications |
