Engine Oil Performance and Engine Service Classification (Other than "Energy Conserving")


<p>This SAE Standard outlines the engine oil performance categories and classifications developed through the efforts of the Alliance of Automobile Manufacturers (Alliance), American Petroleum Institute (API), the American Society for Testing and Materials (ASTM), the Engine Manufacturers Association (EMA), International Lubricant Specification Advisory Committee (ILSAC) and SAE. The verbal descriptions by API and ASTM, along with prescribed test methods and limits are shown for active categories in Table 1 and obsolete categories in Table A1. Appendix A is a historical documentation of the obsolete categories.</p> <p>For purposes of this document, active categories are defined as those (a) for which the required test equipment and test support materials, including reference engine oils and reference fuels, are readily available, (b) for which ASTM or the test developer monitors precision for all tests, and (c) which are currently available for licensing by API EOLCS.</p> <p>The current processes for initiating new classifications were developed through the cooperative efforts of the Alliance, API, ASTM, EMA, ILSAC, and SAE. New ILSAC classifications are developed using the procedure defined in API 1509 Annex C. New API “C” categories are added using the procedure defined in API 1509 Annex D. New API “S” categories are added by the API Lubricants Group.</p>


J183_201611 was created to introduce API HD Categories CK-4 and FA-4 before the "first license" date of 01 Dec. 2016. Although this was successfully achieved, the revision process highlighted several items needing updating and/or revision. • Pare down the “more recent ASTM tests” section • Need to update J183 to “catch up” to all the editorial changes that have been made to Tables 1A-1D (due to changes balloted by API for their document on engine oil licensing, API 1509). • Add a service description for Category CJ-4 • Bring obsolete category CF back into J183. Somehow, CF has been completely removed from J183 in some previous revision(s). The intent is to “recycle” as much of the previous write-up(s) on category CF as reasonable, to avoid trying to create one entirely ab initio. • Run through the editorial changes identified by voting members, that were allowed to be deferred to later revision(s). • Other editorial (typo corrections, grammatical errors) as spotted in the text.
