RE: Octane? Tachron in Water Torture?


Of course there is much more to the chemistry than just the burn rate.
However the effect of the stronger chemical bonds  found in higher
octane fuels results in a fuel that does in fact burn slower and resists
igniting prematurely.  At least that's how my Physical Chemistry
professor explained it.  

Since you stated that what I wrote was "completely incorrect" I have to
assume that you in fact believe that 93 octane contains more energy than
89. Or was this just a statement intended to throw a little gasoline on
the flames (so to speak)?

It is nice to read two completely incorrect  analyses of use of octane
as aopplied to internal combustion engines.  Both begin with an
assumption adn make a series of statements that go  downhill from there.

The internet is full of  information that is FACTUAL about octane
ratings and 
how they are derived and  how gasoline manufacturers make gasoline of 
different octane ratings. It is  pretty heavy chemistry, not just slow
burn rate. 

May  I suggest some homework, gentlemen?

Ben, I'm surprised  at you. Usually you have some pretty good basic
behind your  non-mainsteam ideas, reflective of careful research and
This time you  fired without looking, it  seems.

I AM NOT a petroleum  engineer, nor do I ever hope to be one. But when I

needed answers to the octane  questions 25 years ago, I spoke to
chemists and engineers, and learned  more than I can now remember. And
it was NOT 
that octane is  slow-burn.
