It was my understanding that higher octane gas simply
burns at a higher temperature.   Energy contents is no
different so there is no advantage to using higher
octane gas. However, if your timing is advanced beyond
specs and your using a higher octane fuel you will see
increased performance but at a higher combustion
chamber temperature and pressure.   Might as well add
some sodium phosphate to the antifreeze  and bake
well.   gary

I occasionally use Super Unleaded as it yields
slightly better (read:
seat-of-pants) performance when attempting to stay
above 70 MPH up
those
hills when loaded with STUFF.

It's just Regular gas around town.

I only use regular.  I thought that was what we were
supposed to be
using.
Not so?
