1. Scope

1.1 This test method covers an engine test procedure for evaluating automotive engine oils for certain high-temperature performance characteristics, including oil thickening, varnish deposition, oil consumption, as well as engine wear. Such oils include both single viscosity grade and multiviscosity grade oils that are used in both spark-ignition, gasoline-fueled engines, as well as in diesel engines.

1.1.1 Additionally, with nonmandatory supplemental requirements, a IIIGA Test (Mini Rotary Viscometer and Cold Cranking Simulator measurements), a IIIGVS Test (EOT viscosity increase measurement), or a IIIGB Test (phosphorous retention measurement) can be conducted. These supplemental test procedures are contained in Appendixes Appendix X1, Appendix X2, and Appendix X3, respectively.

Note 1Companion test methods used to evaluate engine oil performance for specification requirements are discussed in SAE J304.

1.2 The values stated in SI units are to be regarded as 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, and tubing size.

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 warning statements are provided in 6.14.1.1 and 7.1.

2. Referenced Documents (purchase separately) The documents listed below are referenced within the subject standard but are not provided as part of the standard.
