Yes, there is E95 that is used for some diesel engines. When I read it before somewhere it didn't say some. Just that it was used for diesel. Wikipedia says for some diesel engines. I thought I saw it on the E85 site, but can't find it now.
I am not sure if you seen these sites, but here they are. And yes, butanol as 2 more carbon.
