Wow 
, a 100 octane, it must be expensive? You purchase by the liter, so that must get really expensive I wonder if we will get 100 octane at our gas stations in the US (highest is 93 octane). That would be really nice, especially for acceleration purposes. 
A friend of mine told me that you can purchase race car gas at (I think 110 octane) for about $5 to $6 a gallon depending on mixture and type of car you are competing with.

100 octane is not just 100 octane, because Europe and the US (Canada) uses different standards. Don't know about the rest of the world... In Europe, the Research Octane Number (RON) standard is used, whereas the US uses an average of MON and RON, the Anti-Knock Index (AKI). In comparison, AKI 94 octane in the US is the equivalent of RON 100 octane in Europe. Gasoline pumps typically post octane numbers as an average of two different values. Often you may see the octane rating quoted as (R+M)/2. One value is the research octane number (RON), which is determined with a test engine running at a low speed of 600 rpm. The other value is the motor octane number (MON), which is determined with a test engine running at a higher speed of 900 rpm. If, for example, a gasoline has an RON of 98 and a MON of 90, then the posted octane number would be the average of the two values or 94. It would be too simple to use an international standard I guess
High octane gasoline does not outperform regular octane gasoline in preventing engine deposits from forming, in removing them, or in cleaning the engine. Nor does it improve performances. You should select the lowest octane grade at which the car's engine runs without knocking i.e 91 for E60. Occasional light knocking or pinging won't harm the engine, and doesn't indicate a need for higher octane. On the other hand, a heavy or persistent knock may result in engine damage.

Modern cars have kock sensors. If knocking is detected the ECU turns back the timing. This results in serious power loss.
In the end:
1. You can't damage your engine with low octane gas.
2. With higher octane gas the ECU advances your timing and you have more power.

If it doesn't increase performance, why are they using high octane gasoline then in racing ???

Because they are meant for it ! NOW E60's are meant for 91..

That's what ? 93 octane US ?!?
