Abstract

This specification covers lubricants for two-stroke-cycle spark-ignition gasoline engines that are prone to ring sticking and damage caused by deposit-induced preignition, piston scuff, spark plug fouling, and piston varnish. The engine oils should be tested for performance, ring sticking and piston deposit, lubricity, and preignition.

Scope

1.1 This specification covers lubricants intended for use in two-stroke-cycle spark-ignition gasoline engines, typically other than outboard motors, that are particularly prone to ring sticking, but which are also liable to suffer damage arising from deposit induced preignition, piston scuff, spark plug fouling and piston varnish.

1.2 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.
