100 Octane
Thanks,
You won't see any performance increase unless you're highly modded. My CLK had no performance benefit at the drags on that gas.

The only thing you can get on a military installation is 93 at around $2, no other options. So I end up paying around $7 a gallon for the 100 High Octane Gas.

I dropped $150+ in expensive fuel (at the time it was $6/gallon when 93 went for $2/gallon). Never helped a lick performance-wise, except it turned my exhaust tips a little blue.
our ECUs adjust automatically? aren't they using 100+ in europe?
The reason European fuel has a higher octane rating is they use a different formula. Here in the US this is the following formula:(RON + MON) / 2
In most places around the world (including Europe and Australia), the Research Octane Number (RON) is what’s posted on the pump. There is a second rating called the Motor Octane Number. Both numbers are determined using a variable compression engine, but the MON uses heated fuel, the engine is run at a higher RPM, and the ignition timing is adjusted during the test. The MON is always eight to ten points lower than the RON.
This means the exact same 98 octane gallon of UK fuel, is rated at 93 or 94 octane in the U.S. 100+? I suppose it's available, but I've never sought high octane fuel overseas. My rentals get the cheap stuff
And MarcusF is correct – US number is lower by around 4 points. So our 93 equals to European 97-98.
By the way, lower octane has higher power and burns longer. And higher octane has more controllable burn (something like that). It is my understanding that it’s better to control at the higher RPM, which we don’t use in the daily driving were we need more power at the lower rpm (think stop and go traffic)
unless you're running a different tune that takes higher octane into account, or unless you're running forced induction with high boost and need to control detonation, you won't see any benefit from 100 octane. If anything, your car will run slower as higher octane fuel combusts at a slower rate.
Use the recommended octane for a stock car. Nothing more, nothing less.
The easiest solution is simply getting Toluene, its 114 octane unleaded race gas, you can pick it up at most paint stores in one gallon jugs for $10-13 (sherman williams & etc). You can get it in 5 tanks or 55 gallon drums as well (although its a bit overkill). You only need to run a few gallons to get the effects; honestly anything over 96-97 octane isn't going to really do anything extra. Its totally 100% safe and is already in the gas at the pump (just in smaller quantities obviously). It is not recommended in concentrations higher than 40% (so just add 2 gallons to a full tank, or 1 gallon per half tank, and that's all you need really).
The ENEOS NEW Vigo high-octane gasoline. I think it is only sold in UK and Japan. I think they tried to market it in the US and was rejected.

Summary:
ENEOS NEW Vigo, a sulfur-free high-octane gasoline that the Company began supplying in January 2005, addresses environmental problems with its sulfur-free guarantee by improving fuel and acceleration efficiency by adding a friction modifier, and by providing the leading engine-cleaning capability in the Japanese market. By adding a new high-performance cleaning agent, we advanced the cleaning capability that the previous ENEOS Vigo possessed. The cleaning agent cleans the inside of the engine, and can reduce air intake valve grime by as much as 86%. This in turn reduces the regulated exhaust emission components (carbon monoxide, hydrocarbons, nitrogen oxide) by 10-30%. As it contains a friction modifier (the only such product in Japan), fuel consumption is improved (CO2 emission is reduced) by 3%, and acceleration is improved by up to 5%.
Hence the fact that this is the #1 Rated Gas in Japan for several years.

I don't have any performance mods except for the Supersprint exhaust from mid~back.

ENEOS Sales pitch aside, just make sure its unleaded and not alcohol based and you should be fine. Toluene or Xylene will do the job although Toluene seems to work better IMO, xylene is technically 117 but for some reason the effects were not as pronounced. hope that helps.

With Obama wanting to increase fuel efficiency maybe the Eneos Vigo Gas will get lucky enough to make it to the United States. Then you will be able to test and feel the difference.
Months ago I told my friend who street races his mod'd 1JZ here in Japan to use the Eneos Vigo gas instead; I followed up and asked him the other day if he made the transition over to Eneos Vigo Gas and if he has noticed better performance. In short he said yes and from now on it will be the only gas he uses.
So here you have it
2 People - Tested and Approved
1 Person - Untested, No Factual Data, Unapproved
I tend to lean towards Benchmarks and not White Papers. You decide
The only Eneos Vigo statement I disagree with is the wording of where it states that "fuel consumption is improved (CO2 emission is reduced) by 3%". What I have noticed is a 3% increase in fuel consumption. I would not call an increase of frequently filling my tank improvement.

"Octane is Octane" evidently is not true seeing that I and my friend have tested both types of High Octane gas. I guess someone has failed to read where it states that Eneos has special additional additives which gives a 5% increase in power. The rational is the same difference as adding Toluene to your current tank of gas. Duh~
Now I see why your statements are often corrected by other forum members. 
"ENEOS Sales pitch" HA you make me laugh.
