1.1 This test method is commonly referred to as the L-60 test.2 It measures the oil-thickening, insolubles-formation, and deposit-formation characteristics of automotive manual transmission and final drive axle lubricating oils when subjected to high-temperature oxidizing conditions. 1.2 The values stated in inch-pound units are to be regarded as the standard except for the catalyst weight and oil weight measurements, for which the unit is gram; the oil volume, for which the unit is millilitres; and the alternator output, for which the unit is watt. The SI values in parentheses are for information only. 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 hazard information is given in Sections 7, 8, and Annex A3.
