ACEA E9-16
ACEA E9-16 is a mid SAPS1 requirement Ultra High Performance Diesel (UHPD) lubricants for use in mid drain applications. ACEA E9-16 contains many elements of the North American API CJ-4 specification.
ACEA recommend ACEA E9-16 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.
The main physical and chemical requirements anticipated for ACEA E9-16 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 |
Note 1 : SAPS refers to Sulphated Ash, Phosphorus and Sulphur, the levels of which are often restricted in the latest performance specifications.
The requirements of the Cummins ISM test place emphasis on enhanced soot related wear control for ACEA E9-16. The removal of the Mack T-11 and inclusion of the Mack T8-E test now aligns E9-16 with other E categories with regard to soot handling performance requirements.
E9-16 anticipates baseline performance for Euro VI emission legislation, which has led to extensive adoption of DPFs on vehicles in Europe.
Changes
A number of changes to the requirements for ACEA E9-16 have been introduced in the ACEA 2016 issue of the oil sequences. The changes for ACEA E9-16 are summarised below:
| Test | Change for ACEA 2016 |
| CEC L-112 | New seals materials for oil elastomer compatibility |
| CEC L-109 | New oxidation test with biodiesel |
| CEC L-104 (OM 646 Bio) | New CEC L-104 Biodiesel impacted piston cleanliness and engine sludge test |
| Shear Stability | Test can now be run using CEC L-014-93 or ASTM D7019 for 30 cycles, and ASTM D7019 only for 90 cycles |
