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 ...
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 ...
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 ...
Wikipedia brings the following quote from Rabbi Maimon, father of the Rambam:
"אין להקל בשום מנהג ואפילו מנהג קל. ויתחייב כל נכון לו עשות משתה ושמחה ומאכל, לפרסם הנס שעשה השם יתברך עמנו באותם הימים. ופשט המנהג לעשות סופגנין, בערבי אלספינג, והם הצפחיות בדבש, ובתרגום: האיסקריטין, והוא מנהג הקדמונים משום שהם קלויים בשמן, זכר לברכתו"
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 ...
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 ...
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
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.

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.
,כי אם אסוך שמן: ופי' חכמינו זכרונם לברכה שעובדיה היה מדליק תמיד שמן לבני הנביאים אשר בלילה לא יכבה נרם, ראוי שיהיה נס בשמן:
Interestingly enough, he quotes "Chazal" but I see nobody else mentioning it.
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 ...
According to the Beis Yosef in siman 671 they needed to go through the tahara process of para aduma which took seven days and one more for the oil making. He also brings the Ran who says the oil refinery was 4 days travel away. Four there, four back, there's eight days for you.
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.
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 ...
Since there are a variety of opinions out there, I thought it would be worth including the metaphoric law of the land: the Italy Kosher Union. On their Kosher Food list, they write the following:
Extra virgin olive oil is generally allowed without control
In general, all extra-virgin olive oil are permitted.
Other oils like soybeans, corn, ...
The olive oil we get in the store is not really pure olive oil, as such it has nothing to do with that Gemara. Our "pure extra virgin olive oil" is roughly 30% real olive oil, the rest is made up of other cheaper oils or processed to change the natural taste of the oil.
See here and here for starters, but this seems to be a well documented fact.
In fact, ...
Rambam (Hilchot Megillah u'Chanukah, ch 3) states that we celebrate the military victory and the re-institution of Jewish sovereignty in Israel. We celebrate for 8 days because the oil burned that long.
Rabbbi Michael Taubes in a YU shiur “Berachot on Worldly Pleasures” quotes the Ramban (Chidushei HaRamban to Berachot Chapter 8, s.v. nireh li) who writes that the benefit has to be from something which enters into the body; this is why no berachah, he says, is recited over things like a cool, refreshing shower, a nice hot bath or a pleasant breeze, even ...
