Can One 2 Cycle Engine Oil Serve the Growing Outboard Market?

The demand for a specially formulated lubricating oil for 2 cycle engines continues to grow. As the rise in output per unit and the number of different engine models and designs continue to increase, lubrication problems steadily rise.

This paper presents engine test results on a number of base stock and detergent additive combinations. Several production model 2 cycle engines ranging in size from 3–80 hp were used.

The results of these tests indicate the complexity of the problem of satisfying the lubricant requirements of all the various engine models and designs with a single lubricant product.
