Greetings…I would like to know halacha about the oil of non-Jews. thank you
The oil of non-Jews is not prohibited in any special way, however on a practical level like many other products nowadays, we have to make sure that it contains only kosher ingredients, and that it wasn’t processed with machinery that wasn’t kosher. However as far as “the oil of a gentile” there is no problem with that.
See Yore Deah 114-7.
