To combat ethanol, I only know of two product - Sta-Bil Marine, and Yamaha Fuel Med RX.
Both products eat the ethanol in your gas. Both products are also fuel stabilizers. You can get the Sta-Bil Marine at any Wal-Mart. You can get the Yamaha product at any Yamaha motorcycle dealership (they should carry it). The Yamaha product comes in a little 3.2 ounce bottle, similar to the little 2-stroke oil bottles you get for your weedeater, and it should cost under $2 for it. <thumbsup>
Shib, believe it or not, I'm very familiar with most of those gas stations on that list - sources for Race Gas in Phoenix. I've been to alot of them before. Also, there's a Love's in Sierra Vista, off Buffalo Soldier Trail, that sells VP100 and VP110 at the pump, but it's not on that list.
