Is this bad for the 2k3????
Are you talking stock engine condition? If so, it won't really do anything for you, except maybe get you slightly worse gas mileage due to change in burn characteristics of the higher octane fuel. Now if you're boosted, it will help you out because the engine won't have to pull as much timing to compensate for the preignition you normally/usually get when using 91-93 octane fuel. I have no expereince with using 100 octane fuel in this platform, but I have used it in several others that were turbocharged...so I am basing my informed opinions on that information.
My friends put in 100 octane "airplane fuel" from an airport 2 weeks ago and nothing happened to their cars....so this week i decided to try it on my car and nothing went wrong.......I put in like 4 gallons to a more than half full tank of 93 octane.

just because his car didn't "roll over and die" immediately doesnt mean its not bad for it EVENTUALLY...but keep using it bro....

OK, so it probably raised the total octane rating to like 94.5...which is still a far cry from the 100 octane you posted in your question/poll. And why did they use AVGAS (which contains lead additives). They WILL absolutely regret that later...

BAsically,
The higher the octain rating the more compression you can run on your engine without having to worry about pre-ignition otherwise known as detonation which will quickly burn a hold right through your piston.
In answer to the question "if it's so good why don't they sell it everwhere?" The higher the octain rating the more "refined" the gasoline is & thus the more it cost to refine it.
Guess that you boys are just a might too young to remember the old sunnoco pumps where you simply turned the dial to select the octaine rating that you wanted, all the way up to 103! (this is what the 11:1 compression HO engines run). I used to run my bikes on 100.
Running higher octain than your engine needs to prevent pre-ignation does only one thing for you.... it spends more money than you need to.

At select 76 locations in California they do sell 100 at the pump. San Jose and Stockton are two that I can think of. I say it's good and it will eliminate any detonation (pinging) you might be having from the crappy 91. At least in California

AVGAS is leaded but the 76 race gas I'm talking about is not. The original post did not specify AVGAS.

I thought he stated it rather plainly myself...
a friend of mine has a tack car running a completely built engine running a fatty turbo uses 100+ octane....not a street car and he gets the gas at a performance shop...dont know if itll do any good to a stock car, might even harm?

Its not going to hurt anything, but I dont think it will help either. It just means that you would safely be able to bump compression or advance timing if you had a chip or something.
Its probably useless to run 100 in a stock NA engine.

DOnt know if it hurts or not but I know airplane fuel is rated 100LL which is low lead. Dont know if lead is harmful to our engines or not but just letting you know that it does contain lead.

Won't hurt the engine but it will smoke the catalytic converter. The lead binds or coats the platinum in the cat and makes it useless. It will affect emission tests, in some cases even start making it fail emissions. Doesn't take much either.
Anyone that puts leaded gas in a cat-equiped car deserves this>

How did you friend get ahold of airplane fuel. They are not designed the same as regular fuel that we use in our cars everyday. It's not a bad thing but it can cause a lot of pressure on the parts while will blow apart, perhaps fracture the piston rod. Since higher octane require more engery to denotnate the combustion. So why do you think Aircraft use turbine fan instead of car engine. I would advise against using it if you were putting it in on a regular basis.

What in the world are you talking about
? I don't know too many piston driven aircraft that have turbines...I can only guess that you are confusing AVGAS and Jet Fuel (we used JP5 in the Navy). AVGAS is very similar to regular automotive fuel, except that it's usually higher octane and contains lead additives. Jet fuel, on the other hand, is like a mixture of some of the characteristics of diesel and kerosene...

Is putting in 100 octane bad or good for the engine?
Post ONLY if you know what you are talking about PLEASE!
The original post (above) said 100 octane. He didn't mention avgas until you asked if he was all stock. I did not read all of the replies before I posted because this was supposed to be a poll. A simple misunderstanding. My bad on not seeing avgas 3 or 4 replies down
