Summary

This service bulletin explains how to measure for oil consumption and possible reasons for loss of oil.

 


Information on Engine Oil Consumption Guidelines

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.
