Who runs ethanol gas?

[ubtripn]

I have two stations in Boise selling non-ethanol. Its all I use since I put my crate motor in. Around here we have E10. What I was told was that means 90% gas and 10% ethanol.

Now the E85 - I was told it is 15% gas and 85% ethanol. That must be wrong.

In any case, since gas prices are down so low I am driving my truck everywhere (talk about a great time for all with classics) but I think I need to upgrade gaskets and fuel hoses to run even E10. Some said I don't have to but my Husqvarna lawnmower developed crystals off E10 that I had to remove then it ran fine again.

Does anybody just run the E10? Have you had issues? Sorry in advance if this is a sore topic.
