Fuel Conservation Practices
The efficiency of the engine can affect the fuel
economy. Perkins design and technology in
manufacturing provides maximum fuel efficiency in all
applications. Follow the recommended procedures in
order to attain optimum performance for the life of the
engine.
• Avoid spilling fuel.
Fuel expands when the fuel is warmed up. The fuel
may overflow from the fuel tank. Inspect fuel lines for
leaks. Repair the fuel lines, as needed.
• Be aware of the properties of the different fuels.
Use only the recommended fuels. Refer to the
Operations and Maintenance Manual, “Fuel
Recommendations”for further information.
• Avoid unnecessary idling.
Shut off the engine rather than idle for long periods of
time.
