Kosher Oil, Wicks, and Candles for Chanuka: Difference between revisions

# On Friday afternoon if one puts in the exact measure required, enough oil for a half hour after Tzet, he can use the unfit wicks and oils (wicks and oils unfit for [[Shabbat]] candles). However if he puts in a lot of oil to last longer than the half hour after Tzet, he may not use the unfit wicks and oils (wicks and oils unfit for [[Shabbat]] candles).The Shamash on Friday afternoon can’t be lit with the unfit wicks and oils.<ref> Meiri([[Shabbat]] 21b), Sh”t Rashba 1:170, Bet Yosef 673, Rama 673:1 say this difference by Friday afternoon. S”A 672:2 rules that if the oil lasts longer than the required half hour it’s permitted for benefit. Therefore, the Bach 673, Pri [[Chadash]] 673, Eliyah Raba 673:5, Pri Megadim M”Z 673:2, and Mishna Brurah 673:6 write that there’s a concern that one will fix the wick to draw better and violate [[Shabbat]]. Similarly the Bach 673, Shaarei Knesset Hagedolah 673:5, Magen Avraham 673:1, Eliyah Raba 673:3, and Pri [[Chadash]] 673 write that the Shamash can’t be lit with unfit wicks and oils because it’s permitted for benefit and there’s an issue of fixing it to improve it. </ref>

# Some have the Minhag to add some water to the oil as long as the wick is immersed in the oil so that it’s able to light. <Ref> Yafeh Lelev 2, 671:2. </ref>

# [[Chanukah]] oil that was left under a bed should preferably not be used for [[Chanukah]] candles but if there’s no other oil available one can use that oil. <Ref>Piskei Teshuvot 663:5 </ref>

# Oil which is inedible, according to most opinions is totally fit and permissible to be used for [[Chanukah]] candles, however, some say that it’s preferable to use edible oil. <Ref>Piskei Teshuvot 673:5, Shevut Yitzchak (vol 5) in name of Rav Elyashiv </ref>
