Hi Eric: Ya I have seen this one and had actually posted on gasoline with no Ethanol here in our area. Alberta, Canada. We still have Esso, Shell and Petro Canada with 91 octane with no ethanol. There is a cheap way to check for Ethanol in gasoline. You take a small water bottle and put about 1" to 1-1/2" water in it. Draw a line at that water lever. You then fill the bottle couple inches from the top with the fuel your testing. Need room to expand and shake. Shake the mixture up slowly as the bottle will pressure up some. Let it settle after shaking for approx 5 minutes. If the fuel contains ethanol it will mix with the water and can be seen very clearly as the water level on the bottle will now be higher. Our 91 fuels here have no Ethanol. Our 94 from Chevron is ethanol free. Most all other 94 octane fuels here have ethanol.
When we dynoed our engines here they made the most power on 94 fuel that contain ethanol. We run ethanol gas in the summer months but never let it sit in the carburetor for long periods of time.
