Lighting the Menorah

In the stores these days, there are myriad varieties of candles and oils to use for Chanukah lights. However, it is clear that the choicest way to fulfill the mitzvah of lighting the menorah is to use olive oil. The miracle symbolized by lighting the menorah is that olive oil that should have lasted only one day lasted eight. Therefore, it is most appropriate to use olive oil for Chanukah lights.
Indeed, the Maharal of Prague was of the opinion that while any oil can be used, wax candles should not be used at all. Wax candles are so dissimilar to the menorah lights in the Beis HaMikdash that they do not properly reflect the miracle. The halachah is not in accordance with this opinion. Wax candles or any oil may be used. Still, it is most preferable to light with olive oil.
An interesting question was raised about wicks that are wax-coated to facilitate easy lighting. When one lights these wicks, the wax burns before the oil. Can one still observe the hiddur mitzvah of using oil for the lights with wax-coated wicks? Rav Shlomo Zalman, zt’l, answered in the affirmative. The wax burns off rather quickly and the olive oil begins to burn soon thereafter. In essence, the individual is using olive oil, just with a little help from the wax.
