This standard specification describes four categories of two-stroke-cycle gasoline engine lubricants based on their miscibility with gasoline and their low-temperature fluidity. The lubricant categories are classified according to the temperature at which the tests are conducted. The lubricants shall meet the requirements for viscosity and miscibility with gasoline. Miscibility test method shall be done using a rotator, graduated cylinders, stoppered flask, and freezer, and shall use reference oil and any full-boiling-range gasoline as indicated in the specification. Fluidity test method shall be done using Brookfield viscometer and its associated equipment. All test method shall be in accordance with the calibration and standardization procedure indicated in the specification.



1.1 This specification describes four categories of lubricants intended for use in two-stroke-cycle spark-ignition gasoline engines based on their miscibility with gasoline and their low-temperature fluidity.

1.2 The following safety hazards caveat pertains only to the test methods described in this specification. 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.

1.3 The values for temperature, pressure, and so forth stated in SI units are the standard.
