you can also mix in toluene or xylene both has much higher octane rating than normal race gas and is cheaper. I have used both for many years. Tons of information if you google them.
However, increasing octane rating on your gas is not going to do any benefit unless you are programmed for it. It can you a factor of safety from detonation.

5th Gear did a show on Octane Booster that will answer your question. Here is link http://au.youtube.com/watch?v=2jbcCr2ll3c

I have used both toluene and xylene, from the days that I worked at a small refinery here in PA. We called it the 'Asprin" for lousy gas. Heck, I had a 55 gallon of toluene in my garage during the mid 80's.
On a side note, I have been running supercharged cars since 93, and have had EXCELLENT results with 104 black label. It is a CHEAP alternative IMHO, and it works. I have plenty of open track days as proof, during 90 degree plus days of 20 minutes of wide open throttle to back this up.
Above all else, just as you said, if your car does not need it, aka higher octane, you will LOOSE power with it. A car only needs a finite amount of octane, and too much actually hurts performance due to a slower flame front. If your vehicle isn't tuned for it, or doesn't require it, you gain NOTHING.
See yeah

FYI: Toluene = 114 octaine.
I have two 5 gal tanks if anyone needs some.

Dead on my friend

I'd like to also add that most octane boosters don't really boost octane...they prevent or reduce detonation. They were marketed to the muscle car owners with high compression engines that wouldn't run on the reduced octane of gas in the late 70's. Toluene works well for this.
There are a few boosters that actually increase octane and also additives that are oxygenators and contain their own oxygen plus other additives for increased performance.
I've tried most of them with mixed results. Klotz "NITRO" produced the most noticable increase for me in my shifter Kart and Cobra replica but I would NEVER put that stuff in my MB. It requires jetting up the carbs for the increased oxygen and I don't know if the ECU in the E could handle that.
