I just bought 10 gallons of 114 to boost up my octane after winter storage. It was $4.69/gallon. thats up about $1/gallon from a year ago.

Compression, compression, compression. If you don't run a high compression engine, you don't need high octane. Octane prevents pre-ignition caused by compression. In a higher compression engine, the fuel/air may (will) explode under compression before the piston reaches the top of it's stroke. Imagine the stresses when that happens. That little "knock" you here is your piston being jammed back down on it's up-stroke. Not good! However, as many have stated above, if you don't need it, don't spend the money on it.
