Sort of my question. In about 1969 when I was a lab tech for a small college I was given 5 gal out of a 55 gal barrel of transformer oil they had for X-ray machine transformers. I still have that pail, tightly capped, sequestered in a junk but dry trailer away from my buildings. Haven't gotten it to haz mat disposal yet. I often wished there was an easy test for PCBs. If it were PCB free it would be nice to have.
