No, it's a total myth.
It will neither increase your mileage nor your power. High-octane fuel is simply a cleaner version of the hydrocarbons used in regular unleaded fuel. It cuts down on the knocking because it is more resistant to self-ignition. And knocking as many unfortunate people have found out, damages your engine. However, not all cars are able to handle high-octane fuels.

No;
Do not waste your money on high octane gas if your car does not require it, it only makes more money for the oil company, most of the methods for raising octane is to add ethanol and that doesn't get as good a mileage as gas alone.

Oh yes it does. Not only does it give better gas mileage it actually is a lot better for the engine. You also will get better Pick UP and restore a lot of loss Horse Power. Because of gas prices, i put Regular gas in, and about 2 or 3 times a month i put Premium. It really helps

Yeah, it is possible to get better gas milage using a higher octane gasoline, but the difference usually is Max: 4-5% only.
But that is alot, if you do not drive a long way to/from your destination, be it work, school, or the bars. LOL (joking, really)
I only use 91 octane in my Ford F-150 flareside, but about every other fill up, I will also add a good fuel injector cleaner additive in the tank, also; this keeps your cylinders free of mold and mildew, er, uh, carbon buildup, whatever~
Like Reverand Rod Flash said once, I get High on the Real things in life: A Clean Windshield, Powerful Gasoline, A shoeshine.... Take Care, lil Bro!

Only use higher octane gas if you have a high performance engine that has high compression or if you have problems with predetination.
If you have a regular engine and don't have problems with predetination, high octane gas will decrease performance--including mpg.
High octane gas is less explosive. High compression engines will cause regular gas to explode prematurely so it's necessary to use high octane gas in them.
Less explosion--less power

No. Higher octane is for high performance engines. Although the gas is cleaner (no sediment), it burns hotter. Use the middle grade if you want, but nothing over 91 octane. Use what your manufacturer recommends.

No. the higher octane is designed for high performance engines.

The extra mileage you gain by using premium gas is negligable.

No, you get better mileage by driving slower, and being easy on the accelerator.
