GRADES CC, CD CF AND CG-4. THE USE OF THE lllGHEST GRADE AVAILABLE IS
RECOMMENDED. THE OIL YOU SELECT SHOULD BE USED ON A REGULAR BASIS WHEN
POSSmLE.

Oil Pressure
The engine's oil pressure, during operation, is indicated by the oil pressure gauge on the instrument panel
During normal operation, the oil pressure will range between 35 and 55
NOTE: A newly started, cold engine can have an oil pressure reading upwards of 60 psi. A
warmed engine can have an oil pressure reading as low as 35 psi. These readings will vary
depending upon the temperature of the engine and the load placed on the generator.
