100 Octane stations in CA

There are quite a few 76 stations here in California that pump 100 octane. Here is the list:

This is arguable, but I believe the answer is yes.

Yes you will get a small boost in HP using 100 octane..

When I tried 100 in Vegas in my 91 z-28, the difference was noticeable... can't imagine what the SS will do

How does using 100 octane without any change to timing net any power?

I imagine the LS3 is smart enough to know when its there, but a 91 Z-28?

Explain! =)

Higher octane burns slower = longer burn cycle = less strain on motor (the horsepower piece is arguable). It seemed more efficient and the car pulled harder. About 10 miles into the tank, I noticed a difference

My daily driver picks up 50hp when I throw 100 octane on it , However I have a separate file to run it (push of a button)

I always thought these gas stations were there for old cars that absolutely needed the higher octane. However, I thinks it's great that some of you guys have gotten noticeable preformance increases! Since different levels of octane do mix proportionally, ie. half a tank of 92 + half a tank of 100 = a full tank of 96, I wonder what the optimal ratio would be to give you a noticeable increase without having to fill the whole Camaro up with 100. I don't have any problem spending the extra 20 cents a gallon for Supreme (91/92 octane), but I really don't want to fill up a 19 gallon tank at $8.20 a gallon...$155.80

I have a station about five miles from my house. I go there to fill my 5-gallon gas can with $40 of 100. It hurts the wallet, but I can run more aggressive timing and not have to worry about torching a piston.

Octane rating
From Wikipedia, the free encyclopedia

The power output of an engine depends in part on the energy density of its fuel, but similar fuels with different octane ratings have similar density. Since switching to a higher octane fuel does not add any more hydrocarbon content or oxygen, the engine cannot produce more power.


Source==http://en.wikipedia.org/wiki/Octane_rating

Why do people believe all the nonsense other people write? Andyrew, 50 HP? you're crazy. Octane slows the fuel burning so that it burns while the piston is on the downstroke, therefore the energy is released on the downstroke rather than the upstroke causing power loss and ping. Octane does not add any more energy to the fuel mixture that is not already there. It does not help clean your engine. It has none of those properties. It is only neccessary in high compression engines to prevent knock. If your engine is tuned properly and there is no knock present, adding octane is simply a waste of money.

This may be true, but my right foot doesn't agree

You're absolutely right. It's an anti-knock agent, nothing more. Merely an old wives' tale placebo effect these guys are "feeling".
