Just an FYI for everyone around the capital district in NY. There is a chain of locally owned stations selling 91 octane, ethanol free gasoline. Look for a 'Pit Stop' station. Also, their 87 octane comes out of the pump treated with the additives to combat the ethanol issues. There is a pretty good number of stations, so you should be able to find one with out too much inconvenience. I lucked out and have two to choose from within 5 minutes of my shop. Prices are competitive.
