We recommend people to mix a few gallons of 100 octane with 91 octane on the track. It will not, however, fix any sort of DI seal failures. That has also been proven as well.  |
What about 93 octane? Of course it's better than 91, but I'm wondering how well it fares compared to 100, for instance, is it 99.9% as good as 100, or only marginally better than 91...

There is a 103 octane pump near me... and I could fill up a 5 gallon gas tank next time I go to the track.

That's not a bad idea at all. Even if there's no additional power to be had, it's a nice safety net for a track day.
