I ran 100 on a stock tune when I ran out of gas at a road course. Car has never ran better, but I drove like a blind grandma so I dont melt my pistons. lol. I put 2 gallons in and went to the gas station and filled up with 87. Car sure ran smooth, I know I must of burned off all carbon deposits.

octane rating is a measurement of resistance to preignition.. meaning simply its more difficult to ignite. if you dont have a bump in timing, compression ratio, or boost, theres no reason to up the octane.

Are you tempted to buy a high octane gasoline for your car because you want to improve its performance? If so, take note: the recommended gasoline for most cars is regular octane. In fact, in most cases, using a higher octane gasoline than your owner's manual recommends offers absolutely no benefit. It won't make your car perform better, go faster, get better mileage or run cleaner. Your best bet: listen to your owner's manual.
The only time you might need to switch to a higher octane level is if your car engine knocks when you use the recommended fuel. This happens to a small percentage of cars.
Unless your engine is knocking, buying higher octane gasoline is a waste of money, too. Premium gas costs 15 to 20 cents per gallon more than regular. That can add up to $100 or more a year in extra costs. Studies indicate that altogether, drivers may be spending hundreds of millions of dollars each year for higher octane gas than they need.
What are octane ratings?
Octane ratings measure a gasoline's ability to resist engine knock, a rattling or pinging sound that results from premature ignition of the compressed fuel-air mixture in one or more cylinders. Most gas stations offer three octane grades: regular (usually 87 octane), mid-grade (usually 89 octane) and premium (usually 92 or 93). The ratings must be posted on bright yellow stickers on each gasoline pump.

Name a fuel nowadays that doesn't have the "cleaning additives" in it? Good luck.
Most people run 100+ octane at the track because they have a specific tunr for it. But there are other reasons to add some higher octane fuel when racing. Engine coolant temps and intake temps can be higher, thus causing your car to be more prone to pinging; having higher octane helps prevent that and saves your engine.
93 is not more pure, the number measures resistance to preignition - just like dom said. There's different ratings out there because automobile manufacturers don't all produce engines that require the same fuel. You'd be surprised how many cars out there require 91 or higher octane.
But, it's your money; keep spending more than you have to...
edit:
HA! You changed your post...I'll leave mine as is so people can enjoy your brilliance...

I've personally taken a log of my car and MPG with my gas. This is why I made that other thread of "What is your MPG" last week. I've never noticed any difference in Performance wise bewtween 87 and 93 on STOCK tuning. Mods to the car were a Full exhaust and CAI. I'm waiting for summer to see if I see a difference between 93 octane on my tune and 87 on stock tune.
It is true that 93 COULD help your car run smoother or clean out your engine such as carbon because of cleaning additives. My friend's RSX Type-R runs better and better MPG for him when he uses 94 octane, but I don't. (BTW I smoked his *** last night)
