ASTM D3607-08(2016)

5.1 The removal of volatile materials such as gasoline dilution from used engine oils is especially important if the mechanical shear stability or oxidative stability of the oil is being monitored by measuring a kinematic viscosity change in the oil after it has been used in a gasoline engine.

1.1 This test method covers a standardized procedure for removing volatile materials such as gasoline and water from used engine oils prior to further oil analysis.

1.2 It also provides an estimate of such volatiles in used engine oils.

1.3 When an accurate value of the gasoline contaminant is required either Test Methods D322 or D3525 shall be used.

1.4 The values stated in SI units are to be regarded as 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 consult and establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
