I used to be able to get F&L Racing 105 octane unleaded in 5 gallon jugs. I would dump all 5 gallons to get to around 95.5 octane and it was like you said absolutely great. I ran 100 octane a few times and didn't notice much of a difference from my 95.5 blend.

100% Correct. I think we kind of top-out at 96. However, when you mix a few gallons in the tank, the characteristics of the car are very different.
