I while back I posted something about my mechanic expressing concerns about ethanol going to 15%. I took note and hoped it wouldn't. Don posted a warning on the Mercury forum to be very careful about where we get gas and pay attention to the % of ethanol. He said the country will see an increase in usage now that the restrictions have been lifted. He said that it has not been used in the summer months for 10 yrs but now it will be. How likely is this to happen to a point where we can't find any 10% ?? He said using 15% will cause damage and void the warranty. So I guess some of may very well be screwed this summer if we can't get 10%....or am I "the sky is falling" syndrome? it won't be that bad?
