(Mishnah): Chachamim permit all oils. R. Tarfon says, we light only with olive oil.

R. Yochanan ben Nuri stood up and said "if so (like R. Tarfon), what will people in Bavel do? They have only sesame oil! What will people in Madai do - they have only nut oil! What will people in Alexandria do - they have only radish oil! What will people in Kaputkiya do? They do not have this or this (only kerosene)!''

Rather, you have only what the earlier [Chachamim] forbade (in the first Mishnah of our Perek).

(Beraisa - R. Shimon ben Elazar): We do not light Tzari, for it is sap [and it is not drawn after the wick, just like pitch].
