Some are accustomed to light for Shabbos, Yom Tov, and Chanukah with olive oil. Is this olive oil (such as the one sold at my local judaica store here) the same type that one can get in a grocery store, or is it specially prepared to burn in a different way?

  • A quick look at the Wiki page for olive oil indicates that it's 100 percent fat. It should all burn quite nicely. The listing they have of the grades/types indicates that even the "lampante" oil that isn't fit for human consumption can still be used for burning. The different "quality" grades are based on how nice it should taste, not how well they burn. – Gary Nov 12 '16 at 7:39

    @NoachMiFrankfurt Well consider clarifying why a question is relevant; such as its combustion characteristics, in the question. – mevaqesh Nov 13 '16 at 3:51

    @Eliyahu Again, any reasons for relevance should be edited into the question itself. – mevaqesh Nov 13 '16 at 4:44

    I don't know. Its cheaper by my local grocer. My guess is that someone (either the supplier or the grocery) realizes that people think that its preferable and will be willing to pay more for it, which is questionable Assur as Onaah. – Eliyahu Nov 13 '16 at 4:44

Olive oil sold in the stores will work fine (or even better than) the Judaica store oils. Some of the Judaica oils are really low quality even though they charge more for it on average.

I've used both and never noticed much of a difference in burning quality.

  • The fancy label costs a lot, ya know... ;) – ezra Jan 4 '17 at 4:55
