1.1 This test method covers an engine test procedure for evaluating automotive engine oils for certain high-temperature performance characteristics, including oil thickening, sludge and varnish deposition, and oil consumption, as well as engine wear. Such oils include both single viscosity grade and multiviscosity grade oils which are used in both spark-ignition, gasoline-fueled engines, as well as in diesel engines. Note 1-Companion test methods used to evaluate engine oil performance for specification requirements are discussed in SAE J304. 1.2 The values stated in either acceptable metric units or in other units shall be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system must be used independently of the other, without combining values in any way. 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. 1.4 This test method is arranged as follows: Subject Section Introduction Scope 1 Referenced Documents 2 Terminology 3 Summary of Test Method 4 Significance and Use 5 Apparatus 6 Laboratory 6.1 Drawings 6.2 Specified Equipment 6.3 Test Engine 6.4 Engine Parts 6.4.1 Hold-Back Fixture 6.4.2 Engine Speed and Load Control 6.5 Engine Cooling System 6.6 Flushing Tank 6.7 Coolant Mixing Tank 6.8 Jacketed Rocker Cover, Intake Manifold Crossover, and Breather Tube Cooling Systems 6.9 External Oil-Cooling System 6.10 Fuel System 6.11 Carburetor Air Supply Humidity, Temperature, and Pressure 6.12 Temperature Measurement 6.13 Thermocouple Location 6.13.1 Air-to-Fuel Ratio Determination 6.14 Exhaust and Exhaust Back Pressure Systems 6.15 Blowby Flow Rate Measurement 6.16 Pressure Measurement and Pressure Sensor Location 6.17 Reagents and Materials 7.
