ICS 75.100                         PCD 25

Revised Standard from Last Update.

1 SCOPE

1.1 This standard covers lubricants primarily intended for use in automotive, four-stroke, spark ignition, air cooled, air-cooled, gasoline engines such as those fitted to scooters, mopeds, motor cycles etc.

1.2 This standard prescribes the requirements for the four grades (see 3) of lubricants as applicable to spark ignited four-stroke gasoline engines.

1.3 Lubricants conforming to the requirements of this standard may also be prescribed/recommended by engine manufacturers for use in other types of fourstroke gasoline engines.
