Component

Engine and engine cooling

Summary

All engines require oil to lubricate and protect the load bearing and internal moving parts from wear including cylinder walls, pistons, and piston rings. When a piston moves down its cylinder, a thin film of oil is left on the cylinder wall. During the combustion process, part of this oil layer is consumed. As a result, varying rates of oil consumption are accepted as normal in all engines. The purpose of this bulletin is to describe different instances where oil consumption occurs and to make available a worksheet to assist the technician in determining if oil consumption is excessive.
