sorry but 10% ethanol isn't a 6 molarity nitric acid
Your 0-rings were about to leak anyhow, IF you had just filled up on the e10...shit, straight methanol takes a long as time to eat through rubber. I've run E85 on a walbro 190, siemens off the shelf injectors, aluminum rail and regulator and NEVER had a leak on the system. Its been this way for 2 years and sits for long periods of time (worst for systems as it then gets time to eat the material).
so your statement =

my ass off
Now being the foremost "expert" out of the group at hand and having tested ethanol (as well as other such fuels) in a both chemistry and IC engines labs, taking courses (and TA'ing) courses on IC enignes, sitting through invitation lectures and reading many SAE papers on it (as a professional SAE member). Hell, IC engines are part of my degree.
So, with that said, E10 will yield a slightly worse gas mileage. Over my
2 years of running it, I had noticed a 1-2 mpg drop in my mileage, as is expected. I will also state that I have yet to hear of anyone having an issue with e10 as part of there fuel system. This being my connections to bass clubs (boat engines and lots of them), working at 2 performance shops, many friends who run garages and shit tons of people who are "car guys" anyhow. Hell even the little old ladies at my church who come to me for car help haven't had any issues...as usual people are blowing shit out of proportion with a lack of knowledge and experience on the subject. It can but most likely won't give you any trouble (anytime soon).
