Precision matrix for Chrysler Oxidation and Deposit test to finish in mid-September

Precision matrix for the Chrysler Oxidation and Deposit Engine Oil Certification Test is projected to be completed by mid-September, according to Kaustav Sinha, Chevron Oronite’s global project manager for ILSAC GF-6/Dexos. Precision matrix testing started on July 21.

Sinha gave an update on the test at the 2015 JSAE/SAE Powertrains, Fuels and Lubricants International Meeting in Kyoto, Japan this week.

The Chrysler Oxidation and Deposit Engine Oil Certification Test is one of six engine tests that will be part of ILSAC GF-6, the new passenger car engine oil specification being developed by American and Japanese light-duty vehicle manufacturers. ILSAC GF-6 licensing is projected to be ready by early 2018.

The test uses a 2014 PentaStar 3.6-L V6 engine. The test that it will replace, the Sequence IIIG, runs on a 1996 GM Powertrain 3800 V6 engine, which is no longer in production. It runs for 90 hours, with a six-ounce addition of oil every 20 hours. SwRI, IAR, Lubrizol, Afton and Ashland have installed the test and contributed to the prove-out matrix data generation.

So far, the matrix team has completed 12 tests out of the 28 tests that will be run in the precision matrix. Five labs, using seven engine test stands, are participating in the precision matrix.
