We also would like to thank you for your continued membership and support and wish you a wonderful holiday season and a healthy and peaceful New Year!

TDG-F-113 – DISI test

The fuel tender is finished and Coryton was selected as the fuel supplier.
The test is now installed and running on Phase 1. The initial validation runs are in line with the expectations.
Everything is on track and the test development should be finished by the end of 2018 as planned.


Candidate oil A has been selected as low reference oil and the results look very promising with all runs failing due to typical pitting and low micro-pitting. One lab showed high runtime with micro-pitting and is doing internal verification. The RR with high reference candidate oil has started and data from 5 labs is available, showing also good results, with the exception of one lab that showed significant lower running time. Internal verification is done here as well.
In October the group held their meeting where the results were discussed. Results show discrimination between low and high candidate oils in running time until pitting failure. For high reference oil a minimum running time may be specified to allow a clear differentiation with the low ref. oil. Preparation started by SDG Officer on low ref. oil to establish precision data and limits. All the open issues of the draft test method should be addressed and finalized at the next group meeting early April 2018.

TDG-L-107 – M271 Sludge Test

The low calibration oil test results gave good results. Everything went well until the high calibration oils were run. The test was aborted at 240 hours and the proposed 280 hours would not have been reached. This point lies at the same hour for the low calibration which is a big concern. The oil was analyzed but no problems were found. The oil pump was checked as well as the fuel dilution and was also good so from the test method side everything is pretty consistent.
Several scenarios were proposed and discussed in the TDG meeting on October 18th and the TDG agreed to use the remaining funds to evaluate the oil consumption at each test condition. This can be done real time by APL. Some test conditions might slightly need to be adjusted based on this information. The whole point is to run the engine at conditions that consume less oil so that there is more oil in the engine and that all engines can get to the end of the test.
This work will be completed by the end of the year. A new fuel batch will also be blended in parallel. The test development will restart beginning 2018 and is foreseen to be completed by the end of March.

TDG-L-114 - Toyota Diesel Turbocharger Compressor Deposit test proposal

The first TDG meeting took place on November 24th where the Chairman and Vice-Chairman have been nominated. The Chairman will be Michael Schulz from ISP and the Vice-Chairman Paul Decker-Brentano from Toyota. The nominations were approved by the CEC Management Board. There are 11 sponsors confirmed for this test. ISP will be the general hardware supplier. A fuel tender process will also be launched by CEC shortly. The test will be installed at the test lab in February/March 2018 and the RR should start in April 2018.

SPG on Low Soot Wear Test

The SPG concluded that a TDG should be formed to develop two low soot wear tests; a Journal Bearing Wear Test and a Ring / Liner Wear Test. The group had a meeting on November 7th where a draft of the Terms of Reference for the bearing wear test has been prepared. When that is completed, the Terms of Reference for the liner wear test will be drafted.

SPG on Corrosion

The Terms of Reference for the SPG on Corrosion have been endorsed by the member associations and they will now nominate members to join and start with the SPG.


CEC has decided to close the Surveillance Group as it becomes more and more difficult to produce elastomers for this old seal compatibility test (RE1 and RE2) and the new elastomer group SG L-112 is well in place. Labs will still be allowed to run the test but they cannot claim a CEC result. If companies/labs don’t have the full set of elastomer for L-039, then they should use CEC L-112. A note was added in the ACEA 2012 sequences and on the CEC website to reflect this decision.


The Test Method is in good control but the QR has deteriorated slightly from r =1.0 and R =0.9 in the original Round Robin (where the test control limits were defined) to r=1.2 and R=1.0. Also since the Round Robin in 2015 to date a reduction in severity in both reference oils has been observed. This is in the region of ~5 merits (Avg PC) on RL 256 (HR) and ~2 on RL255 (LR), effectively increasing discrimination.
4 test laboratories are running the test on a routine basis. Unfortunately Daimler Lubes has had to resign from the group, but a representative from the Daimler Berlin engine plant is able to continue to participate.
The Test method is published and continues to be updated as required.
The Reference Oils and fuel continue to be available.
Test “life expectancy” is now out to beyond 2018. Hardware is being reused so 4 tests in total can be achieved on each cylinder block. Requirements are defined for their reuse and there is no evidence that this change has had an impact on severity, although very little reference oil data is available. A new batch of pistons and rings has been produced and their performance is currently being assessed by ISP.


A group meeting was held on November 8th, 2017 to clarify the fuel blending procedure as the test has a repeatability problem. The data show that the blending procedure has an impact on the test severity. Some group members believe that there are other reasons impacting the test severity but there is no evidence to prove this for the time being.
Based on the recent Low reference fuel results obtained from several labs, it has been agreed that the current test variability with low reference fuel is not acceptable by the SG F-110. Although the test still shows a difference in rating between Non IDID Pure base fuel and IDID Contaminated Low Ref Fuel, the test variability needs to be significantly improved to return to the original RR Outcome. Therefore, the next RR, now planned for completion by end Q1 2018, will include a specific and tighter fuel preparation protocol to minimize as much as possible the Low Ref Fuel related variability.
All RR Data will be loaded on TMS. The next RR outcome will then be reviewed by SDG and statistical criteria will be updated to confirm – or not – the variability issue of the DW10C Test.

If at the end of this RR the test doesn’t not show that it is repeatable, the group will declare the test out of control.

Statistical Development Group - Update of the Statistics Manual

Procedure 2 (Test Monitoring Systems, Analysis of Test Monitoring Data and On-Line Data Depositories) of the Statistics Manual has been updated. A paragraph has been added to section 1.5 “Frequency of Reference Testing” and Appendix D “Considerations for Changing Reference Fluid Testing Frequency in CEC Performance Tests” has been added. You can find the updated section on CEC website.

Overview of the CEC Management Board Meeting on September 26th and November 28th, 2017

The latest CEC MB meetings took place on September 26th, 2017 at the ATIEL offices in Brussels and on November 28th at theCEC offices in Brussels. The following items were decided/discussed:

CEC Test Life Plan
Following feedback from the CEC Strategic Workshop, the CEC Management Board has reviewed the CEC Life Plan. The currentdocument didn’t provide enough detailed information and it was not clear how long the test will be available or when a replacementtest would need to be developed. The title of the document has also been changed to “CEC Test Availability and Life Plan”and now contains 4 spreadsheets (TDG, SG-Fuel, SG-Lubes and SG-Transmission tests). This is a good reference document forthe group chairmen and will be actively used. The file is being updated on a regular basis and is posted on CEC’s extranet (navigate to the extranet at the top and click on the Life Plan under ‘CEC information at the bottom). Somefurther comments on the overall availability of the test were received and additional changes will be implemented. An updatedversion will be available soon.

CEC Communications
A survey has been conducted amongst the CEC members in the past few months to understand from individuals how they use thecurrent CEC communication tools and to better understand their expectations. The results of the survey were discussed inthe Management Board Meeting and the main strengths are that useful and relevant information is available and that qualityof the information is also good. The weaknesses are the ease of use and the look and feel. Therefore this would need to beimproved and the website needs to be much more user friendly for both the users and the back end. The Management Board iscurrently looking for offers from several website providers and the next steps, as well as budget will be further discussedin the coming months.
In the meantime the following improvements have been made to the current website following some comments from different users:

 • Test methods: documents can now be printed/downloaded at the same time
 • Progress reports: a filter has been added so the user can view them by most recent updated instead of by SG/TDG

CEC Management Board Representatives
Due to changing responsibilities for some of the representatives in the CEC Management Board, the following people will representATIEL and ACEA:

 • Neil Briffett and Nick Clague for ATIEL (replacing Volker Null)
 • Paul Decker-Brentano, Bengt Otterholm and Paul Greening for ACEA (replacing Anders Roj and Suhair Abdelhalim)

Chairmen Appointments SG's

Alex Haythornthwaite (Lubrizol) has been appointed as the new Chairman of SG-L-014 and Alex Piquet (BP) as the Vice Chairman.

CEC TMS Updates

Here are the latest developments on the CEC Test Monitoring System:

Completing the data entry process: It is most important that users complete the data entry process and make sure that their data are listed in the ’Registrations‘ table on TMS. The data entry page shows a List of Temporary Data for each test type. The fields are validated by TMS as the data are entered. When the data entry is complete, the Process button on the tope right of the page needs to be selected, and the entries will then appear in the registrations table.
When you select a test type, TMS will tell you if there are completed records that are still to be processed.

Enhanced lab status report: In the Management menu of TMS, the Lab Status Report has been improved. Chairmen and SDG representatives can assign the status of labs and instruments. This status will be reflected in the Admin Report.

SG-L-036: A new version of the HTHS test has been created and is awaiting release. This version records the result of the reference at 100 degrees C.

SG-L-085: Minor modifications have been made to the data dictionary to remove the pan batch number on PDSC data entry.

SG-F-098: As part of an ongoing process to make data entry more easy, the DW10B data entry proforma has been revised and simplified. Accordingly the data dictionary and data entry page have been revised in line with the proforma.  Copies of the latest proforma can be downloaded from the DW10B page on TMS.

SG-L_109: A new field 'V100_NOFUEL', the fresh oil (with no fuel added) KV100 value, has been added to the OXI109 data dictionary. It is in the 'Data Entry' group.

European Base Oil & Lubricants Summit: 28-30 November, 2017 in Antwerp, Belgium
