Higher Octane?

Higher Octane?
Generally stating in any car, can I use 91 octane in a car that says to use 87? I know if you do the reverse you get knocking or pinging. Will using a higher than recommended octane hurt my engine at all? Or will it actually help it?
Cars in question:
2007 Toyota Camry
2008 Mitsubishi Lancer GTS
1998 Ford Explorer XLT

Higher octane doesn't burn faster, it burns slower, that's why turbo cars and high compression cars use it. It's to keep knock in check AKA pre-ignition.

You lost milage because your car spit out unburnt fuel out the tail pipe.
Octane is NOT a measure of power but of the fuels’ resistance to ignition from heat. A higher-octane fuel, under identical combustion chamber conditions, will burn slower.
