Performance Evaluation Of A Versatile Two-Cycle Lubricant Additive 790080

Boating Industry Associations (BIA) TC-W certified two-cycle engine oils are used in a variety of both air- and water-cooled engines. Some high performance two-cycle engines used in the motorcycle and snow-mobile market have shown performance deficiencies with current TC-W quality lubricants. This paper traces the development of an additive capable of meeting the demands of severe air-cooled engine tests as well as the current TC-W lubricant specification for water-cooled engines. Tests developed to evaluate lubricant performance in both air- and water-cooled engines are described. The need for standardized test procedures in addition to the BIA TC-W specification is shown.
