There are two explanations provided for the eight day delay in getting new ritually pure oil.
One opinion is that the oil was produced in a region that was a four day journey from Jerusalem. This is the explanation of the Ran on Shabbos 21b. The Meiri identifies the oil producing region as Tekoa.
The other opinion is that the delay was because they were ...
The Mazal Sha'ah on the Rambam infers that the shi'ur l'chayyev for anointing with t'rumah oil is a k'zayis, based on R' Yehudah's opinion in the gemara (K'risus 6b) who holds that a person is liable for a k'zayis of prohibited anointing with the shemen hamishchah (Commentary to Mishneh Torah, Hil. T'rumos 10:2). (One should note that it is still Biblically ...
See this interesting article by Rabbi Yirmeyahu Kaganoff about the production of olive oil. He discusses the issues of fraud in the market and notes that different kashrut organizations have different views on the matter. He quotes the OU as not requiring certification on extra virgin olive oil only (virgin olive oil still needs). He also quotes the Eida ...
This question assumes that the Rishonim or Acharonim grappled with this question. Most were not aware of contemporary sources omitting this miracle, such that they would ask the question and answer it.
If you want, instead, a defense of the existence of the oil miracle, here are two.
That "II Maccabees is, as is well known, an abridgement of a five-book ...
The mefarshim on this portion of Navi (Targum, Rashi, Radak, etc.) explain that the man who died was actually Ovadiah (see Melachim Aleph 18). He was the man who kept 100 true prophets alive during their persecution by Jezebel. He hid them in 2 caves. He also provided for all of their physical needs. The cost of secretly supporting them, not only risked ...
Aruch HaShulchan 265:12 & 265:13 discusses this. From what I understand the Gemara is talking about placing a bowl of water under the candle where it would be prohibited even from Erev Shabbos, however oil with water in a glass is no issue.
Orach Chaim 265:4 says that so long one has no intention that it is being done to extinguish the flame sooner it ...
Rambam, Hil. Avodas Yom Hakippurim 1:3 (from Yoma 12a-b):
זה שנכנס תחתיו אינו צריך חינוך אלא עבודתו מחנכתו
"The one who replaces him doesn't need any inauguration; his performing the avodah [of Yom Kippur, which is reserved for the kohen gadol] inaugurates him."
So he doesn't need anointing at that time (and not after Yom Kippur either, because as ...
http://www.star-k.org/kashrus/kk-kosher-cons-handbk.htm (footnote 10):
One must also wait six hours if he ate french fries that were fried in oil previously used to fry chicken. Therefore, if one eats
french fries (or other deep fried items) prepared in a fleishig
restaurant, he should assume that he is fleishig unless the
certifying agency of the ...
Per the CRC-Chicago it requires a Hechsher.
Q: Does extra virgin coconut oil require hashgacha?
A: Extra virgin coconut oil does require a hechsher.
Rabbi Abe Sharp responded to my e-mail sent to the CRC-Chicago why a Hashgacha is necessary for extra virgin coconut oil.
It may be due to equipment issues and cross-contamination with
Mishna Berura 298:5 and Beer Hataiv 298:2 mention in the name of the Sefer HaKavonos and the Magen Avraham in the name of the Kavanos HaArizal that it is preferable to use a beeswax candle for Havdala.
As you can see in the Halacha the candle is supposed to be an Avuka - which is more than one wick. This also makes it more practical to use a candle over oil....
They used a half of a lug of oil in each candle every night, in order that it would last through the longest night of the year (Menachos 88b). A lug is 6 egg volumes. An egg volume is disputed, but it's accepted to be either around 57 (R' Chaim Naeh) or 100 (Chazon Ish) mL.
So the volume per candle was about 172 or 294 mL, or about 1200 or 2050 mL total.
Indeed, as Menachem commented, it's not necessary to assume that they were made into a dough. No kometz (handful) was taken from such menachos (see Rambam, Hil. Pesulei Hamukdashin 18:8), so it may not have mattered much whether it could hold together as a solid. (With private menachos, on the other hand, the ratio was 1/10 eifah flour (7.2 log) to 1 log oil,...

Slightly less explicitly, since olive oil was directly associated with light back then:
אמר רב יהודה אורה זו תורה וכן הוא אומר (משלי ו, כג) כי נר מצוה ותורה אור

Logically, you've got to consider the reasons things are considered kitniyos: the item is used to make some kind of flour, the item is grown among chometz species, the item was historically confused with chometz in storage or preparation -- and sometimes, there's just a longstanding minhag that the item is kitniyos.
Sesame is considered kitniyos by every ...
Based on the OK article I mentioned in this answer, coconut oil would need a hechsher.
According to the Wikipedia article on coconut oil, all the different methods of creating coconut oil involve cooking or baking the coconut, and some of the methods involve additives.
The OK article discusses the concerns involved in oil production, and how Extra Virgin ...
The OK has an article (archived link) on olive oil production and kashrut concerns.
In the article they explain the differences between the different levels of olive oil (i.e Extra Virgin, Virgin, Fino, olive oil, and light olive oil), both in processing and in the nature of oil itself.
The article say that:
Only Extra Virgin Olive Oil goes through no ...
According to Shemirat Shabbat K'Hilchato as cited here, there is a leniency regarding oil, which is how Wikipedia describes this product:
Regarding applying hair cream on Shabbat, Shemirat Shabbat Kehilkhatah
writes that one may be lenient and apply hair oil, but only in small
quantities so that one should not come to squeeze it out of the hair.
R Binyanim Tabadi was asked this question by someone who ate one spoon of olive oil every day, enjoyed it and wanted to know whether to make a blessing in light of the gemara you quote. He answered as follows (see here for the full Hebrew response - second question on the right)
There is a dispute amongst rishonim on the proper blessing. The Rambam ...
CANOLA OIL from the Orthodox Union.
Canola oil, which is a form of rapeseed oil, should be considered kitniyot.
The Star-K (Baltimore Va'ad Hakashrus also lists Canola Oil in its list of Kitniyos
CRC goes into the details as to why rapeseed oil (Canola oil) is considered kitniyos (based on Maharsham I:183 that it was used in Europe). Note that the CRC ...
שלא יסוך זר בשמן המשחה - שלא למשח בשמן המשחה שעשה משה אלא כהנים לבד. שנאמר (שמות ל לב) על בשר אדם לא ייסך. ונתבאר בכתוב שמי שמשח (שנמשח) בו במזיד, חיב כרת, שנאמר (שם לג) ואשר יתן ממנו על זר ונכרת. ואם נמשח בו בשוגג, חיב חטאת קבועה. כלומר, שאין חלוק בו בין הדל והעשיר אלא דבר קבוע הוא לכל.

The Malbim mentions it.

Interestingly enough, he quotes "Chazal" but I see nobody else mentioning it.
Olive oil fraud is rampant. Just because something claims to be virgin olive oil, that doesn't mean that it is. Therefore, all other possible issues aside, I would not automatically assume that it is kosher. [A quick test to help determine if you have genuine olive oil is that olive oil should harden in the fridge. If it doesn't, you know that it's not ...
Here's what I understand from the Gemara:
Drinking oil alone doesn't get a bracha since it's mazik- it's like having a stand-alone butter, but a little better for you.
Drinking oil through anigron, the oil doesn't get a bracha because it's tafel to the anigron- think butter on bread. You wouldn't have the oil because it's mazik. It's there to enhance ...
People have told me soaking it in ammonia also works. I soaked my oil glasses in ammonia for a couple of days and it worked pretty well. I did keep it outside while I was soaking it because of the smell and because I have little kids around.
The Sefer Shalal Rav brings many answers such as that rule only applying while the Mizbeach was functional.
Another very clever answer he brings (which seems to me to be the best one) is that Rav holds (See top of Pesachim 17a-רב משקי בית מטבחיא תני, אבל משקי בי מדבחיא מטמא with Rashi D"H Midi Hu- משקה המטבחים דם ומים אבל משקה מדבחיא היין והשמן שהם משקה ...
