2) Engine Lubrication

a) General
Proper lubrication is one of the most important steps in good maintenance procedure. Proper
lubrication means the use of correct lubricants and adherence to a proper time schedule. Lubrication
points, frequency of lubrication, and recommended lubricants are indicated in Figures 1 and 2.
This section incorporates the engine manufacturer's engine lubrication recommendations from their
"Operation and Maintenance Manual."
Lubrication schedule
Time schedules indicated on the Lubrication Chart, Figure 1, are approximate and based on average
operating conditions. It may be necessary to lubricate more frequently under severe operating
conditions such as: low engine temperatures, high oil temperatures, or intermittent operation.
However, time intervals should not exceed those indicated in the chart without careful evaluation.
b) Oil specification
The engine lubricating oil that is recommended by the engine manufacturer is identified by an API
(American Petroleum Institute) classification designation. The manufacturer does not recommend
any specific brand of lubricating oil.
The use of quality lubricating oil, combined with appropriate lubricating oil drain and filter change
intervals, are important factors in extending engine life.
