Frictional and engine cleanliness properties of 2-cycle engine oils are apparently related. This tentative conclusion is reached after comparing results from a friction rig with those measured in various water- and air-cooled engines.Early results also show that: bright stock improves the frictional properties and engine performance of 2-cycle engine oils; additives which impart dynamic stick- slip (chatter) to an oil perform poorly in high performance engines; and insufficient data are available to determine the merits of ash and ashless type detergents.
