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.
