Dave and Pat, from knowing both of you for a long time on this forum, I know what you guys post always is the truth and factual. I respect your opinions. I'm also glad you both (and some others) have had such good success with it. The only thing I can offer is what I have been seeing in the marine industry I was in for the past 25 or so years. For us it has become a major pain. Here are some other viewpoints on the subject:

Another problem with ethanol blended fuel is "Phase Separation". Here is a brief explanation of that issue:

What is ?phase separation?, and how do I deal with it?
If significant amounts of water are present in a fuel tank with gasoline that contains ethanol, the water will be drawn into the fuel until the saturation point is reached for the three-component mixture of water + gasoline + ethanol. Beyond this level of water, phase separation could cause most of the ethanol and water to separate from the bulk fuel and drop to the bottom of the tank, leaving gasoline with a significantly reduced level of ethanol in the upper phase. If the lower phase of water and ethanol is large enough to reach the fuel inlet, it could be pumped directly to the engine and cause significant problems. Even if the ethanol water phase at the bottom of the tank is not drawn into the fuel inlet, the reduced ethanol level of the fuel reduces the octane rating by as much as 3 octane numbers, which could result in engine problems.

So maybe my opinion is clouded because the boat engines I am experienced in are more prone to problems from ethanol than car motors. Cars tend to use up their fuel faster than boats, maybe keeping it fresh enough to not cause the degree of problems boaters have been experiencing. That might be why some hot rodders are also having these problems as our rods tend to sit idle for longer periods than our daily drivers.

Just a thought.
