4、 must send a letter to General Motors (GM) with the form in Appendix A completely filled out. If GM personnel want additional information, the marketer must present the full American Chemistry Council (ACC) data package to GM. Oil marketers must meet all the requirements contained in GM6094M and may
5、 not claim conformance to selected portions only. 3.2 Oils must meet all requirements of the American Petroleum Institutes (API) Engine Oil Licensing and Certification System (EOLCS) for International Lubricants Standardization and Approval Committee (ILSAC) GF-4 certification, as specified in API P
6、ublication 1509, latest edition. The product must have a current API license. 3.3 All engine tests must be conducted according to the procedures specified in the ACC Product Approval Code of Practice, as specified for licensing a product to use the ILSAC Certification Mark. It is the intent that the
7、 product actually supplied under this specification (that is, the final formulation) will have passed all requirements defined herein. In the event that GM does not agree with the suitability of any read across, base oil interchange, or other change, GM reserves the right to require additional testi
8、ng. 3.4 In addition to meeting the Society of Automotive Engineers (SAE) J300 requirements, the candidate oils must also meet the following requirements for American Society for Testing and Materials (ASTM) D4684 with no yield stress (35 Pa): 0W-30 30 000 cP max at 40C (non- critical) 5W-30 40, 000

13、quirements of GMW3059, Restricted and Reportable Substances for Parts. 4.3 Initial Approval. No claim shall be made by any marketer until representative initial production samples, if requested, have been approved by General Motors Powertrain (GMPT) Materials Engineering as meeting the requirements
14、of this specification. 4.4 Inspection and Rejection. All material manufactured to this specification shall be equivalent in every respect to the initial samples approved by engineering. There shall be no changes in either formulation or manufacturing processes permitted without prior notification an
15、d approval by engineering. Lack of notification by the supplier constitutes grounds for withdrawal of approval to the specification. While samples of the product may be taken and checked for conformance to this specification, the supplier shall accept the responsibility for their product meeting thi
16、s specification without dependence upon GMs inspection. The laboratory performing chemical and physical tests on the product must also participate in a proficiency-testing program (round robin) that is approved by GMPT Materials Engineering. Upon request, GMPT Materials Engineering must receive copi
17、es of the proficiency testing reports directly from the test program administrator. 5 Approved Sources Engineering qualification of an approved source is required for this specification. Only sources registered with GM under this specification number have been qualified by engineering as meeting the
18、 requirements of this specification. 6 Coding System This material specification shall be referenced in other documents, drawings, VTS, CTS, etc. as follows: Engine oil per GM6094M 7 Release and Revisions 7.1 Release This material specification originated in April 1989, and was first approved in Mar
