ACEA E4-16 oils are Ultra High Performance Diesel (UHPD) lubricants designed for use in severe duty, long-drain applications.
The main physical and chemical requirements for ACEA E4-16 are shown below.
|HTHS viscosity||CEC L-36-A-90||mPa.s||≥3.5|
|Sulphated Ash||ASTM D874||%wt||≤ 2.0|
|Evaporation loss (NOACK)||CEC L-40-A-93||%||≤ 13|
|Total Base Number||ASTM D2896||mgKOH/g||≥12|
ACEA E4-16 is usually coupled with Daimler MB-Approval 228.5 and MAN 3277, MTU Oil Category 3 and Deutz DQC IV-10.
Daimler, MAN, MTU and Deutz performance specifications build on top of an ACEA E4-16 baseline with additional performance requirements in areas such as wear protection. Daimler MB-Approval 228.5 also specifies an ash level of 1.0-2.0% which prevents low ash formulations from carrying the same approval.
ACEA E6 was first introduced into the ACEA Oil Sequences in 1998. Although the testing requirements for ACEA E6 have been updated with each issue of the sequences it was not until 2008 that the severity was increased. This was due to the replacement of older engine tests with new engine tests.
A number of further changes to the requirements for ACEA E4-16 have been included in the ACEA 2016 issue of the oil sequences.
The changes for ACEA E4-16 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|
|Limits established for ACEA E4|
|Shear Stability||Test can now be run using CEC L-014-93 or ASTM D7019 for 30 cycles,
ASTM D7019 only for 90 cycles.
The relative performance diagrams presented below compare Lubrizol's interpretation of the performance of requirements of the ACEA 2016 E4-16 oil sequence with the ACEA 2016 E6-16 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 E6-16 is designed to have a greater level of corrosion protection and the highest level of compatibility with advanced exhaust aftertreatment systems.
The relative performance diagrams presented below compare Lubrizol's interpretation of the performance of requirements of the ACEA 2016 E4-16 oil sequence with the ACEA 2016 E7-16 oil sequence.
This comparison illustrates how both sequences are expected to provide different performance with ACEA E4-16 providing similar bore polishing but greater piston cleanliness than ACEA E7-16. ACEA E7-16 provides a higher level of performance in terms of wear protection, soot handling and corrosion protection.
