that guy is probably running nitro-methane. I would think F1 is using a very high octane specific racing fuel, maybe 110 or higher. most super-fast drag cars are nitro-methane. i'm not sure what nascar uses, it should be 94 octane, since it's suppose to represent a "stock car," but idk...

Not surprised to octane rating for F1's around 110, might even to further extent today.
