– Q. Dear Rabbi. Is it permitted ‘lekatchila’ (on the onset) to use olive oil for Chanuka lights that was left uncovered overnight in a bottle?

Horav Shlomo Miller’s Shlit’a opinion is that as the Talmud (Chulin 49b) teaches, there is no overnight issues on oil. (See also Beis Yosef Y.D. 116: and Nitei Gavriel 18: !8).
