If they smoke too much & blacken the chimney, you've got 'em turned up too high.
That's not the oil, it's you.
Clean the chimney, trim the wick, adjust the wick just high enough in the burner to light, put the chimney back on, and then adjust the flame higher till it starts to blacken the glass again. Back it off to where it doesn't & that's your max high setting.
