Where can you buy 97 octane pump gas?

About 165 psi on a compression gauge is the limit for using pump gas that is readily available on any corner (probably 91/92/93 octane). 91 is all you can buy here in The Socialist People's Republic of Mexifornia.
Run the motor to bring the coolant temperature up into the normal operating range. Remove all spark plugs to make the motor easier for the starter to turn over. Disable the hot line to the ignition coil to prevent a fire. Allow at least 5 "chuffs" from each cylinder to allow the test gauge needle to reach the max reading. I like to have a spare, fully-charged battery standing by....or another vehicle that I can jump from in the event I run down the test vehicle's battery. Have a good set of jumper cables standing by also.
