Chigma, I add this Starbrite additive that stabilizes and has some enzeme stuff that helps stop this "Phase seperation" that ethanol causes, .................. the ethanol cleans all the crud on the walls and causes problems in the filters.
Haven't we already been burning this stuff for the last several seasons? What is changing for this season? Who would be the authority on this stuff? Who would regulate the chemistry of the new blends? Department of Energy? You can spend an hour with Google chasing down this stuff.
The regulations are there. The mandates and the laws. Congress has said "you -will- use this stuff" They (Gov't agencies) admit that there may be a noticeable loss of efficiency. They have left it to the manufacturers to deal with fallout associated with changes in the chemistry of the fuel.
Eventually they'll figure out a way to handle the less efficient fuel, and the other unforseen side effects such as the alcohol acting as a solvent for water and other impurities or emulisifier of normal gasoline paraffins and waxes. Just think, in the winter we add drygas (isopropyl alcohol) to our automobile gas to absorb water and prevent freezups. The more alcohol they add to our boat fuel, the less chance we will have of seeing water in our Racor filters
The Usenet FAQ on Gasoline has been consolidated here: UseNet Gasoline FAQ
It's full of everything you would ever want to know about gasoline.
Now the question is......how should we best store the stuff in our tanks.. and what is Yamaha going to tell us about how it affects their engine performance?
