ASTM D5844-98

1.1 This test method covers a laboratory engine test procedure, utilizing a 1977 350 in. displacement (5.7 L) Oldsmobile V-8 engine. The procedure, using leaded gasoline, evaluates the rust inhibition characteristics of engine oils. The test method was designed to relate particularly to short-trip service under typical winter conditions in the upper midwestern United States. The procedure has been correlated with vehicles, using leaded gasoline, in that type of service and prior to 1978, particularly with regard to rusting. It is one of the test methods required to evaluate oils intended to satisfy the API SH category.

1.2 Information Letters are published occasionally by the ASTM Test Monitoring Center (see Appendix X1) to update the test method. Copies of these letters can be obtained by writing the Center.

1.3 The method may not be applicable for the evaluation of engine oils if unleaded gasoline is used.

1.4 The values stated in inch-pound units are to be regarded as the standard. The values given in parentheses are for information only.

1.5 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.
