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...
