Hey VX Nation!

I was driving on a desolate highway in CT, in need to fill my gas tank, so I wasn't picky about my choice of gas stations. I see this old, run-down Sunocco station with the old style pumps, no pay-at-the-pump, etc. I start pumping my gas, when I look across from my island and see a lone gas pump that touted a very rare 110 Octane-Sunocco's special "Race fuel"-at a price of $7 a gallon!
What is so special about this higher octane? A full tank of gas would cost us $150!! What in the world could possibly justify $150 for a single tank? All you performance guru's, please educate me!!
