lower octane burns faster... as such, it doesn't get a chance to burn all of the fuel, it's more of a flash ignition... so you don't get the most efficient use/performance of all the fuel, since it's not all being burned...
higher octane burns slower, so it's considered more efficient, since more of the fuel is actually being used/burned to provide performance...
so yes, you'd probably get better mileage with a higher octane fuel...

hahahaah...
well, may I stand corrected then...
I've always known it to be that higher octane fuel burns slower than lower octane fuel...
"The higher the octane rating, the slower the fuel burns. Therefore, the lower the octane rating, the faster the fuel burns. Now at first this may sound like a bad thing, and many ask "Shouldn't a higher octane burn faster and be better for my car?"
The answer is no. If you've ever heard a "ping" in your engine and someone has told you to get a higher octane fuel, that is because the ping is acutally from the explosion of gasoline in the engine. Gasoline should not explode, but rather it should burn as quickly as possible. A lower octane rating will burn faster, and under the right conditions actually explode, causing that undesireable ping. Upgrading to a higher will allow the fuel to burn slower, therefore not exploding. "
"High octane fuel has more detonation resistance compared to lower octane fuel.
High Compression Ratio + Lower octane = Faster Combustion = Preignition/knock
higher octane = slower combustion"
