I ordered a can to check it out from e-bay for $26.95 including shipping.
Here is my response from Boostane:
Nick,
BOOSTane will help stabilize and slow the negative side effects (corrosion and hygroscopy) of Ethanol, as well as increase the effective octane. However, there is no specific blending chart for this, as we can not predict the quality of ethanol as it is so all over the board.
However, we are aware of customers that have had success with 1 can of BOOSTane Premium per full tank of E85
