The EPA has not yet authorized the 15% mix for small engines and marine use. In addition the recommened 15% blend is for year models of 2007 and later. Even the 10% blend has been a nightmare for marine use AND older "fuel cells" in race cars. In Hawaii the local Formula Ford teams soon discovered that every race car with an older fuel cell tank was damaged and had to be replaced. Pissed off a bunch of folks... Not to mention the mariners who were well beyond pissed.

That narrow criteria for recommended use is virtual proof that they know the 15% blend is going to be a problem for a LOT of people. A very bad decision on so many levels.
