What level does growlithe learn flamethrower?

Torkoal learns flamethrower at level 13, and learns flamewheel at level 15.

Actually Torkoal learns flamethrower at level 30. And although the question didn't ask for "Flamewheel" I'd like to say that "Flamewheel" is not a Pokemon move at all, but I'm assuming they meant "Fire Spin" which Torkoal learns at level 17.
