It is a rating to determine a fuel`s resistance to auto ignition.
A higher rating means a fuel will ignite at a higher temperature.

Bigger is better. Keep in mind they all have same BTU in them. Only difference is each step from regular is additives to slow burn rate.
Why regular unleaded gets better fuel mileage in a car designed for it over premium.
Now if it's 10% ethanol, it's slightly lower btu as compared to non ethanol.
Key issue here is how and where you drive. And temperature. Not to hot a climate, level ground and you drive easy using gear ranges, regular unleaded will work. As long as it doesn't ping or rattle when you accelerate.
If it does, go to midgrade or premium. A maximum of 10 % ethanol is great. It keeps moisture out of the tank and helps are farmers out.
It's good for 6 months in a semi-sealed tank without anything added.
With all those modifications, sure you need the big number.

However octane adds no BTU (AKA ... power or horse power) to gasoline.
