I have a good friend that has a stock 64 Falcon Sprint. He always uses premium gasoline and nothing say can convince him he is wasting money on premium. Remember, it has a 260 cu. in. engine. Even if the premium fuel does help (which it doesn't) it still isn't going to make much power. I had a 65 Mustang convertible powered with a 260 between Viet Nam tours. It was fun but not a performance machine. Of course, that didn't prevent me from driving it like it was.
Would someone explain how cooling the fuel increases performance. You can densify it by cooling to get more fuel in but that just makes it more rich resulting in less power. That is not difficult to do anyway. Bigger jets will do it on carbs and reprogramming the ECU on electronic fuel injected engines.
I know cooler air is more dense and can get more oxygen in into the engine which lets you also add more fuel to maintain the best air fuel ratio. Kind of like turbo or supercharging. I just don't get the cold fuel trick. I know at one time when F1 didn't allow refueling and they had to carry all their fuel with a maximum capacity tank, some teams were caught cheating by filling with cold fuel right before the race. That allowed them to use more fuel because it would expand as it warmed up. It didn't improve performance though. The extra fuel just let then drive harder longer than the teams not cheating.
