Scope

1.1 This test method covers and is commonly referred to as the Sequence VG test,2 and it has been correlated with vehicles used in stop-and-go service prior to 1996, particularly with regard to sludge and varnish formation.3 It is one of the test methods required to evaluate oils intended to satisfy the API SL performance category. 1.2 The values stated in SI units are to be regarded as the standard. No other units of measurement are included in this standard. 1.2.1 Exception—Where there is no direct SI equivalent such as screw threads, national pipe threads/diameters, tubing size, or specified single source equipment. 1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. Specific hazard statements are given in 7.7, 7.10.2.2, 8.3.4.2, 8.4.4.3, 9.2.6, 9.3.4.5, 12.1.1.7, 12.2.1.4, and Annex A5. 1.4 A Table of Contents follows: Section Scope 1 Referenced Documents 2 Terminology 3 Summary of Test Method 4 Significance and Use 5 Apparatus (General Description) 6 Apparatus (The Test Engine) 7 Sequence VG Test Engine 7.1 Required New Engine Parts 7.2 Reusable Engine Parts 7.3 Specially Fabricated Engine Parts 7.4 Special Engine Measurement and Assembly Equipment 7.5 1 This test method is under the jurisdiction of ASTM Committee D02 on Petroleum Products, Liquid Fuels, and Lubricants and is the direct responsibility of Subcommittee D02.B0.01 on Passenger Car Engine Oils. Current edition approved May 1, 2017. Published May 2017. Originally approved in 2000. Last previous edition approved in 2016 as D6593 – 16a. DOI: 10.1520/D6593-17. 2 Until the next revision of this test method, the ASTM Test Monitoring Center will update changes in the test method by means of information letters.
