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. This test method is commonly referred to as the Mack T-9.

Formerly under the jurisdiction of Committee D02 on Petroleum Products and Lubricants, this test method was withdrawn without replacement in October 2009, because the necessary equipment to conduct the procedure is no longer available.

This test method was developed to evaluate the wear performance of engine oils in turbocharged and intercooled four-cycle diesel engines. 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.
