If you REALLY need high octane try turbo blue gas, that's 100 octane but it's not cheap by any means. It cost me about $8/gallon over 15 years ago so I'd be afraid to look now.

There's also VP Racing fuel, you can buy that in drums as small as 5 gallons I believe. Some motorcycle & speed shops sell it, if you can't find one that does you'll have to go to a race track.

For older piston airplanes there's stuff like c18, etc but again you'll have to call around.
