ACEA E6-08 Issue 2
Overview
ACEA E6-08 Issue 2 oils are low SAPS1 Ultra High Performance Diesel (UHPD) lubricants designed for use in 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).
ACEA E6-08 Issue 2 oils are typically SAE 10W-40 based on API Group III base oils. The main physical and chemical requirements for ACEA E6-08 Issue 2 are shown below:

ACEA E6-08 Issue 2 is usually coupled with Daimler MB-Approval 228.51 and MAN 3477.
Both Daimler and MAN performance specifications build on top of an ACEA E6-08 Issue 2 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.
Changes
There are a number of changes to the requirements for ACEA E6-08 Issue 2 in the ACEA 2010 issue of the oil sequences.
The changes for ACEA 2010 are summarised below:
| Test |
Change for ACEA 2010 |
| OM602A |
Replaced by OM646LA |
| OM646LA |
Wear test evaluating exhaust cam wear |
| OM441LA |
Replaced by OM501LA |
| OM501LA |
New test evaluating engine and piston cleanliness |
| Mack T12 |
Replaces Mack T-10 for evaluating wear and corrosion. |
Not only does ACEA 2010 bring changes in the engine hardware used in the evaluation of ACEA E6-08 Issue 2 oils, both the new OM646LA and OM501LA tests will also be the first engine tests in the Heavy Duty Sequences to be run with a modern 5% biodiesel (B05) fuel.
Relative Performance
The relative performance diagrams presented below compare Lubrizol’s interpretation of the performance of requirements of the ACEA 2010 E6-08 Issue 2 oil sequence with the ACEA 2010 E4-08 Issue 2 oil sequence
This comparison illustrates how both sequences are expected to provide similar performance in terms of bore polish, wear protection, soot handling and piston cleanliness. However, ACEA E6-08 Issue 2 is expected to have a greater level of corrosion 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 2010 E6-08 Issue 2 oil sequence with the ACEA 2010 E9-08 Issue 2 oil sequence.
This comparison illustrates how ACEA E6-08 Issue 2 is expected to provide a higher level of aftertreatment system compatibility and piston cleanliness. Both are expected to provide similar performance in terms of bore polish and ACEA E9-08 Issue 2 a greater level of corrosion protection, wear protection and soot handling.
