I'm going to have to admit that she is the most BITOG member that exists: Frying up fish in Motor Oil.
The chemistry in motor oil is not safe for human consumption. Many years ago there was a news clip about some foreign country where food was fried in motor oil and the results were devastating to those who consumed it. Granted that that was several decades ago so the chemistry of motor oil has changed but there is no way that this can be considered to be safe for human consumption.
