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 mPa.s ≥ 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

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.

Note 1 : SAPS refers to Sulphated Ash, Phosphorus and Sulphur, the levels of which are often restricted in the latest performance specifications.


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 summarised below:

Test Change for ACEA 2016
CEC L-112 New elastomers for the oil elastomer compatibility tests
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

Relative Performance

The relative performance diagrams presented below compare Lubrizol’s interpretation of the performance of requirements of the ACEA 2016 E6-16 oil sequence with the ACEA 2016 E4-16 oil sequence.

ACEA E6-16 and ACEA E4-16

ACEA E6-12 vs E4-12

This comparison illustrates how both sequences are expected to provide similar performance in terms of bore polish, soot handling and piston cleanliness. However, ACEA E6-16 is expected to have a greater level of corrosion protection, wear protection and the highest level of compatibility with advanced aftertreatment systems.

The relative performance diagrams presented below compare Lubrizol's interpretation of the performance of requirements of the ACEA 2016 E6-16 oil sequence with the ACEA 2016 E9-16 oil sequence. The introduction of new biodiesel tests are reflected across the relevant axis in the performance tool.

ACEA E6-16 and ACEA E9-16

This comparison illustrates how ACEA E6-16 is expected to provide a higher level of aftertreatment system compatibility and piston cleanliness. ACEA E9-16 has a greater level of corrosion protection, wear protection, soot handling and bore polish performance.
