I used to obtain used transformer oil for quite a low price in the '90s. This I used "as is" as a substitute for diesel in my Isuzu pick-up for 4 years with no ill effect on the engine, diesel pump or injectors.
Well, it worked for me! I think that just about any oil will do what diesel does if injected into compressed air (containing oxygen) - combustion will take place and that's what you want.
A diesel burns its fuel. A shop that makes french fries doesn't burn the oil. I think burning fry oil will make black smoke and stink as bad or worse as a diesel that burns petrolium diesel fuel.
You may be thinking of PCBs which were used in transformers prior to the 1970's. Hopefully Jtech didn't accidentally burn any of that in his Isuzu pick-up.
Hero, diesal fuel doesn't need to be flameable at atmospheric pressure, the high compression ratio of the diesal engine is what makes it work with such a wide variety of fuels. Put it under a decent amount of heat and intense pressure and just about anything will combust.

Hopefully not, because it can cause skin cancer after continuous exposure to the oil containing pcb's. I did get info on what to do with transformer oil containing pcb's and the pro's said the only effective way to get rid of it, was to incinerate it! A diesel engine can do that quite well!
No actually it can't. PCB's aren't destroyed unless they're heated to 1200+ Celcius in a oxygen rich fuel mixture for more than 2 seconds (at least acording to Wikipedia) Diesal engine combustion definitly doesn't qualify as incineration.
