 Using high octance to run cooler only applies to high compression engines.
For arguments sake lets say 8:1 an up -- The "modern" hi-tech engines.
With these you may/will notice a difference in engine operation.
 However, when you can count the compression ratio with one hand, there is
nothing the gasoline affects by way of pinging or heat creation. Theres no
chance for anything to happen.  I think it was Bill that said you could put
a mouse ontop of the piston (I like that little explanation) and it wouldn't
know anything happened except for an up and down ride on the piston.
In such a case, hi octane gas is not going to do anything for you. And it
won't do anything for the engine.   All these engines do is burn whats there
by nature of burning alone--when you bump up compression, then you start
relying on "voodoo" =) science and you introduce side effects (pinging,
heat etc.) as compression increases, and thats what high octance gas is for,
minimising these side effects.  For, if you put a mouse in these engines,
it would be a squished little flat bugger, especially at 12:1. =)  At BTC
you may have the same cylinder volume, but at TDC, that volume has been
radically reduced (compressed) and gases create heat as they are compressed.
No compression, no heat. No high octance required.
