Fiznat for El Presidante!!!

And for the question for the bonus round is, If the first and second ring of the piston are to be 180degrees of each other are the 2 rings on top and below the squigly oil ring thing also to be placed 180degrees of each other. Must answer in correct format, per Alex Trebec.

That is the oil control section of the piston so the more you can seperate those rings the better.
