1.1 This test method is commonly referred to as the Sequence VE test² and has been correlated with vehicles used in stop-and-go service prior to 1988, particularly with regard to sludge and varnish formation and valve train wear. It is one of the test methods required to evaluate oils intended to satisfy the API SJ performance category.

1.2 The values stated in either inch-pound units or SI units are to be regarded separately as the standard. Within the text, the SI units are shown in parentheses when combined with inch-pound units. Some of the figures and forms have identical numerical designations, but with the letter M following the numerical designation: these are alternative figures and forms that contain SI units.

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 precautionary statements are given in 7.7, 7.8.9.6, 7.8.13, 7.10.2, 7.10.3.2(c), 8.3.4.2, 8.4.4.3, 8.4.5.2, 9.3.4.4, 9.6.1.2, 12.1.1.5, 12.1.4.5, 12.2.1, 12.2.1.5, Fig. A3.6, and Annex A8.
