Abstract
Problems associated with use of oils for small air-cooled two-cycle engines are mainly piston deposits, ring sticking, spark plug fouling, combustion-chamber deposits, piston seizure, exhaust system blocking and visible smoke.
This paper describes some test methods for evaluation of lubricants for Japanese small air-cooled two-cycle engines.
Results obtained from some of these test are also expressed.
The effect of base oil composition and additive type on lubricant performance is also described.
