One should light only with the inedible oil.

 

One should light only with the inedible oil. Food or drink, if placed under a bed there is a רוח רעה resting on it and may not be eaten. יו"ד סי' קטז ס"ה The בן איש חי פ' וישב writes such oil may not be used to light Chanukah candles. However, if the oil is inedible it's not considered food and there is no רוח רעה on it, therefore, may be used for Chanukah candles.
