What you have there isn't pure ethanol it says right on the top ethanol blend blended with what denaturing agent I am referring to pure ethanol
This link may be better. En.wikipedia.org/wiki/ethanol
This thread is about ethanol in gasoline. What you refer to as "pure ethanol" doesn't wind up in your fuel tank. Not from a bowser anyway..
The MSDS I linked to might say "Ethanol Blends" at the top but then later on says :
CHEMICAL NAME: CAS No: PROPORTION:
Ethanol 64-17-5 >95.5%
Water 7732-18-5 To make up to 100%
Sure, a denaturing agent (most usually methanol) is added at or before the loading gantry in line with government regulations, but it wouldn't be more than 10% - of the 10% of the "Ethanol" that winds up being sold as E10.
In summary: "E10", as you buy it at the bowser, is ordinary ULP (if there is such a thing) containing up to 10% "Ethanol" (it could also, legally, be anywhere between 90% and 100% ULP - but that's a whole separate discussion). That "10% Ethanol" may contain up to 10% methanol and up to 1% water (it might not also) depending on the customer - hardly enough to do any damage on it's own, but worth consideration anyway.
It's worth remembering that someone once said "Oils ain't oils!" - well, guess what, "E10 mix ain't E10" either and will vary widely from 100% gasoline downwards depending upon the time of year, the cost of production and where you buy it from.
EDIT: It seems what we call "E10" over here, you guys call "gasohol"
