Because I'm on the comp list, I get my Cruising World after everybody else . . . (I think they wait for returned issues .. . give me a week or so to be able to comment on the article.
If you mean 15% ethanol, that's E15.
E85 is 85% ethanol and is available some places like the corn belt but only specially built engines can use it.
For the moment, E15 is supposed to be used only in late-model automobile engines (I think I read 2004 or something like that . . . don't have the bulletin handy). That means with our older model cars we'll have to read the pumps very carefully.
The ULSD thing came up among the Good Old Boat editors just the other day. It's been a fact in California since 2006. Everyone else is just catching up.
I did a bit of Googling but couldn't come up with any hairy scary stories (not like the E10 in old boats horrors). The official gummint page on the subject said the needed additives are put in before retail distribution.
