That's amazing to hear -- did not know anyone sold or used E85. I still hate ethanol gas, but E85 should have an octane of around 109!
We have lot of E85 around here (Ohio) but you need a car tuned for it to take full advantage. It would not work in a car designed for E10. But in the right car it can be pretty amazing - I had a 2011 Buick Regal turbo as a company car, which is designed for flex fuel and has larger injectors to take advantage of the E85. Since E85 is 105+ octane the wastegate stays closed longer and the power is amazing. Tuners are getting 375+ HP out of the 2.0 liter GM turbos running E85.
But - no free ride - fuel economy on E85 is about 25% less than on E10 due to the lower energy content of ethanol versus gasoline. Back then I was driving a lot of miles, and really enjoyed the power, but the constant fill-ups were a pain and I ended up going back to E10.

I am waiting for the new WaWa to open down the street. Supposedly going to have ethanol free high octane gas. Probably have to pay a premium for NOT having something mixed into it. Just like laundry soap...buy the fragrance free stuff and you pay more because they don't ADD fragrance or perfume. The world is a strange place.
Well, you pay more for a GT3 with less stuff on it!
I'm not smart enough to know what the answer is. But it worries me that we feel the need to increasingly use food for fuel. I guess in the next 20 or 30 years we'll see. Until then I'll keep filling my little P-cars with whatever they sell me at the pumps.
The above link covered changes to Porsche oil standards as well as ethanol compatibility for all Porsche models. Long story short, everything before the Boxster and 996 is only approved for E5 (5% ethanol), which requires adding fuel additives to protect fuel system components.
A more general email about ethanol in general, for those who want to read it, can be found here:

Hey Charles,, what bits of the 996 fuel system (If any) would you keep an eye on as far as Alcohol exposure,,
I know the fuel hoses on the old 911's were horrible for self destructing if they got E* in them.. As well as injector o-rings..
I ran a race car on pure alcohol back in the mid 80's. It is a wonderful fuel for a Turbocharged Race Engine, but is very dry, I had to mix in some Ester based top end lube oil to lube the valve guide and top rings.
It also absorbs water like a sponge. Back then if buying by the barrel in 55 gallon barrel was $2 a gallon, but it took twice as much alcohol to go same distance so compared to gasoline was $4 .
My 996 doesn't have any issues with E10, but all my small engines do !!! weedeaters, lawn mowers , and chainsaws will stop up the small jets if let sit for 4-5 months during the winter. I buy non-ethanol for the small engines. but I have to go out of my way to get it so I get 10 gal at a time.

No. Best we can deduce is that perhaps the extended use of E10 fuels may have something to do with the injector problems we are seeing.
My next service item I was considering was sending the injectors out for refurb..
I run good fuel, and techron in all the cars I own usually a tank before an oil change..
I figured a 03 should be fairly safe generally on E10/15 But I wonder what will happen with E20..

We have had several sets of injectors sent out to be cleaned and tested that have passed to then only fail shortly thereafter. We only use new injectors now, when and where available.
Ethanol is hygroscopic and corrosive for some metals in your block. Such as aluminium. it deteriorated the components that are in direct contact with it.
If your car was made in a period where ethanol was not considered as a possible additive to the fuel a lot of components are made of materials which in fact are not ideal for running with low concentrations of ethanol.
with the right choice of materials the problems that ethanol causes can be delayed not eliminated.
I have used the Lucas Ethanol treatment below on vintage cars based upon a recommendation from a vintage car forum. I really don't know if it helped or not. Reviews on Amazon seem to be good:
