Hi Ben...

PCB = poly chloronated butinol   or something of that nature   a more 
safer test is to put a few large drops of the oil into water...  if it 
sinks to the bottom or there abouts  its a PCB type oil ...  if it 
floats its most likely not PCB oil... more likely a mineral or castor 
oil.  If it has a blueish to  clear blue its most likely a GE style oil 
( btw which will stink  kinda a sweet sticky smell ) PCB type oil has a 
golden or reddish color...
