ACEA E9-12

Overview

ACEA E9-12 is a new mid SAPS1 requirement Ultra High Performance Diesel (UHPD) lubricants for use in mid drain applications. ACEA E9-12 contains many elements of the North American API CJ-4 specification.

ACEA recommend ACEA E9-12 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.

ACEA E9-12 oils are SAE 15W-40 based on API Group II base oils and 10W-XX based on either API Group II or Group III or a mix of Group II/III base oils. The main physical and chemical requirements anticipated for ACEA E9-12 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 ≤ 0.12
Sulphur ASTM D5185 %wt ≤ 0.4
Evaporation loss (NOACK) CEC L-40-A-93 % ≤ 13
Total Base Number ASTM D2896 mgKOH/g ≥ 7

The unique inclusion of the Mack T-11 and ISM engine tests in this category places an emphasis on enhanced soot handling performance and soot related wear control. This means that ACEA E9-12 takes a global position, aligning with global OEM specifications such as Daimler MB228.31, Volvo VDS-4 and Deutz III-10LA.

E9-12 anticipates baseline performance for Euro VI emission legislation, which demands mandatory DPFs on all vehicles in Europe (aligning with EPA 2010).

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

Changes

A number of changes to the requirements for ACEA E9-12 have been introduced in the ACEA 2012 issue of the oil sequences.

The changes for ACEA E9-12 are summarised below:

Test Change for ACEA 2012
CEC L-105 Low Temperature Pumpability test added

Relative Performance

The relative performance diagrams presented below compare Lubrizol's interpretation of the performance requirements of ACEA 2012 E9-12 oil sequence with the ACEA 2012 E7-12 oil sequence.

ACEA E9-12 and ACEA E7-12 

ACEA E9-12 vs E7-12

This comparison illustrates how both sequences are expected to provide similar performance in terms of bore polishing and piston cleanliness. However, ACEA E9-12 is expected to provide a higher level of performance in terms of corrosion protection, soot handling, aftertreatment compatibility and wear protection than ACEA E7-12.

The relative performance diagrams presented below compare Lubrizol's interpretation of the performance of the ACEA 2012 E9-12 oil sequence with the ACEA 2012 E6-12 oil sequence.

ACEA E6-12 and ACEA E9-12  

ACEA E6-12 vs E9-12

This comparison illustrates how ACEA E9-12 is expected to provide a greater level of corrosion protection, wear protection and soot handling than ACEA E6-12. ACEA E6-12 has a higher level of aftertreatment system compatibility, piston cleanliness and bore polish resistance.
