[AT] Mixing High Octane gasoline and Diesel fuel

[DieselBob at aol.com]

Dean's reference has it right per my background.  The only things I  can add 
is I can't remember octane having much to do about actually changing  flame 
speed, but higher octane fuels resist "auto-ignition" or detonation and  allow 
the flame to consume the fuel mixture before it detonates.  
 
Diesel's generally run smother on high cetane fuel as it "auto-ignites"  
faster before a lot of fuel is injected and mixed.  They start better and  have 
less noise or diesel rap.
