ASTM D322 for gasoline diluent in used gasoline engine oils by distillation
1. Scope
1.1 This test method covers determination of the amount of dilution in crankcase oils of engines when gasoline has been used as the fuel.
NOTE 1 - There may be cases in dispute, therefore, the user of this test method is advised to establish whether this method will be accepted. There may be cases where Test Method D3525 results will be set as the referee value.
1.2 The values stated in acceptable SI units are to be regarded as the standard.
1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use.
