[Psml] Electric Motor Oil Question

[C. Henry Depew]

Greetings!
       I am trying to repair a slump pump with a wiring problem.  I 
took it apart and had a puddle of very light oil appear 
unexpectedly.  From the looks of things, the oil is inside the pump 
case with the motor.  It must be non-conductive since it covers the 
motor if you turn the pump on its side.
      Anyone have an idea as to what type of oil this is and were one 
obtains a fresh supply?
