ACEA E6-16
ACEA E6-16 oils are low SAPS1 Ultra High Performance Diesel (UHPD) lubricants designed for use in severe duty, long drain applications.
ACEA recommends their use in vehicles fitted with aftertreatment systems for the reduction of particulate matter (DPFs) and oxides of nitrogen (EGR and/or SCR), in combination with low sulphur diesel fuel.
The main physical and chemical requirements for ACEA E6-16 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 | ≤ 0.08 |
| Sulphur | ASTM D5185 | %wt | ≤ 0.3 |
| 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.
ACEA E6-16 is usually coupled with Daimler MB-Approval 228.51 and MAN 3677, MTU oil category 3.1 and Deutz DQC IV-10 LA.
Typically Daimler, MAN, MTU and Deutz performance specifications build on top of an ACEA E6-16 with additional performance requirements in areas such as wear protection.
Changes
There are a number of changes to the requirements for ACEA E6-16 in the ACEA 2016 issue of the oil sequences. The changes for ACEA E6-16 are summarized 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 |
| CEC L-085-99 (PDSC) | Limits established for ACEA E6 |
| 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 |
