| Significance and Use | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
|
This test method was developed to evaluate the wear performance of engine oils in turbocharged and intercooled four-cycle diesel engines equipped with EGR and running on ultra-low sulfur diesel fuel. Obtain results from used oil analysis and component measurements before and after test. The test method may be used for engine oil specification acceptance when all details of the procedure are followed. |

| 1. Scope | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
|
1.1 This test method covers an engine test procedure for evaluating diesel engine oils for performance characteristics, including lead corrosion and wear of piston rings and cylinder liners in an engine equipped with exhaust gas recirculation and running on ultra-low sulfur diesel fuel. This test method is commonly referred to as the Mack T-12. 1.2 The values stated in either SI units, inch-pound units, or other units are to be regarded separately as the primary units. 1.2.1 For each parameter, the primary units are shown first. Secondary units may be shown in parentheses, for information purposes only. These secondary units may or may not be exact equivalents to the primary units. 1.2.2 SI units are provided for all parameters except where there is no direct equivalent such as the units for 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. See Annex A6 for specific safety precautions. |
