בהעלתך את הנרות
Which oil may be used to light Shabbos candles but not Chanukah candles?
Oil from שמיטה may not be burnt unless you benefit from it while it is burning.
You may benefit from the light of Shabbos candles, therefore, Shmitta oil is O.K.
You may not benefit from Chanukah candles, therefore Shemitta oil is not OK.
