Mine was used for motor oil as well. Did a good burn out and power washing and it was nice and clean. Like was mentioned...all metal has some sort of lubricant on it at some point. Once you season it you have layers of buildup between your food and the metal anyway. Been using it for about two months now without any issue or odd tastes or anything.
