DETROIT DIESEL
LUBRICATION AND PREVENTIVE MAINTENANCE
To obtain the best performance and long life from a Detroit Diesel engine, the Operator must adhere to the following
schedule and instructions on lubrication and preventive maintenance.
The daily instructions pertain to routine or daily starting of an engine and not to a new engine or one that has not been
operated for a considerable period of time. For new or stored engines, carry out the instructions given under Preparation
for Starting Engine First Time under Operating Instructions.
The time intervals given in the chart on the following page are actual operating hours or miles of an engine. If the
lubricating oil is drained immediately after an engine has been run for some time, most of the sediment will be in
suspension and, therefore, will drain readily.
All authorized Detroit Diesel Allison Service Outlets are prepared to service engines with the viscosity and grade of
lubricants recommended on the following pages.
