Octane Level
Being that gas prices are so high,I was wondering if I were to run 100 Octane gas if it would hurt my stock engine.By the way,the 100 octane is 9 cents cheeper than mid-grade gas where I'm from.

Yeah it's a separate pump a the gas station for cars going to the race track to race.What's really funny is the price on that pump really doesn't go up or down very much at all.I guess it must not be that reformulated gas or something.

Higher octane = slower burn.
High compression ratio NA engines, boosted engines (such as TC or SC that run high compression pressures under boost), and cars running N20 require higher octane fuel to prevent knock. Knock is spontaneous combustion, aka "detonation", and is a lot more likely to occur under the severe aforementioned conditions.
If you were paying more for higher octane fuel, I would say you were pissing your money away. But since you are not, I don't think it is going to hurt anything. On the other hand, it won't be of any benefit to you, either. Except that in some cases, the premium fuel grades have slightly better detergents and less gums than the cheaper stuff. But, it's a very trivial difference.

BTW, leaded gasoline was phased out a long time ago due to the health and environmental consequences that go with it. Plus, lead poisons O2 sensors. The high octane fuel on the market is unleaded, to the best of my knowledge.
