ROBO Update
The ROBO Bench Test is being considered as an alternative to the Sequence IIIGA for aged oil low temperature pumpability. ROBO Round Robin Testing indicated a mild severity bias on Sequence IIIG reference oils at some laboratories and corrective actions are being taken. However, ROBO will not be ready for a June ASTM ballot but may be ready by December 2008.
Sequence VID Consortium Update
The Sequence VID Fuel Economy Test has completed all vehicle testing and four out of planned five development matrices. Stand design information is likely to be released in the next few weeks. A two month delay in starting the precision matrix is expected. In order to keep the timeline on schedule to meet 3Q 2010 first API license date, the Precision Matrix will be reduced from five months to three months.
ASTM VID Matrix Design Task Force Update
ASTM VID Matrix Design Task Force is hoping to have a recommendation for the ASTM PCEOCP in June.
ESCIT Update
The Emissions System Compatibility Improvement Team, ESCIT, recommended the Sequence IIIG @ 100 hours with the Percent Phosphorous Retention method to be used for measuring Phosphorous Impact. A move to accept this recommendation was tabled so the individual trade organizations - ILSAC, API LC, ACC can discuss. (Click here for more information on these trade organizations)
Also, a letter will be sent by ILSAC/OIL to the Sequence IIIG Surveillance Panel Chair to implement the proposed improvements to the ICP method used in the procedure
Review of GF-5 Timeline
The following issues could impact the Timeline:
• To keep on schedule the Sequence VID Precision Matrix needs to be complete by 3Q 2008.
• The Sequence VIII Surveillance Panel has agreed to buy another batch of bearings to counter the lead leaching problem. These bearings will not be stored in oil.
• ROBO will not be ready for a June ASTM ballot but may be ready by December 2008.
Draft GF-5 Specification
ILSAC response to January 2008 OIL-side revisions
ILSAC responded to OIL side January 2008 counter proposal for the GF-5 specification.
ILSAC proposed relaxing IIIG weighted piston deposits, VG Sludge Parameters, and used oil aeration volume.
In addition, it was agreed to drop the D1748 Panel Rust Test for E-85. The Ball Rust Test was deemed sufficient for rust protection.
ILSAC was opposed to allowing the Sequence IIIGA as an alternative to the ROBO. There was a concern that if the ROBO isn't forced on the industry ILSAC/OIL will not have experience with it and it may not be reliable.
ILSAC proposed keeping the remaining test parameters at the original draft levels.
Preamble to GF-5 Draft Specification
ILSAC and OIL discussed the change in the preamble to the GF-5 draft specification.
OIL asked ILSAC to explain the changes they made to the February 2007 draft. ILSAC said that what was intended was to reflect what OIL requested in an early GF-5 discussion.
10W-30 Sulfur Levels
Data was presented on sulfur and 10W-30 ILSAC oils. ILSAC appears ready to negotiate and offered 0.6% wt.
Seals Task Force Request
The ASTM Seals Task Force to evaluate relative vs. fixed limits for some seal parameters proposed by OIL was accepted and a letter will be sent to ASTM. ILSAC indicated relative limits may be higher.
Aeration Presentation from GM
GM offered an example of the need for air entrainment measurement. GM stated that hardware is a factor in the air entrainment issue but the oil needs to contribute to solving the problem.
