The fuel system is specifically built to handle E10-E15 fuel without any issues or performance loss. E0 fuel in michigan is extremely expensive and offers zero benefits.
I started running a 50-50 mix of E85 with premium E10 fuel as a way of dealing with spark knock in my SD4. (after reprogramming the ECU of course) So far it is working fine and have not seen any adverse effects of the alcohol on the stock fuel system.
As mentioned by DarkHorizon the system was built to handle E10. The only advantage to running E0 would be a slight increase in fuel mileage. But if it costs you more than E10, then net/net you haven't saved any $$

Its only a dollar a gallon more, for the 20 gallons I buy a year I'll spend the extra buck..
E10 and E0 collect the same amount of water at the same RATE but E10 will hold a very slight amount more. This is why alcohols are used as storage stabilizers and fuel line antifreeze so that the absorbed water into the Gasoline part of fuel phase seperates the alcohol can absorb the water left behind and prevent it from freezing.

A bit wrong...
E10 or Station Pumps labeled 10% or "up to 10%" Ethanol is Fine w/ old cars not just Fiero. Even in the 70's most OM and other docs from car makers say 0 - 10% E and 0-5% Methanol. (Methanol is mainly used in "Dry Gas.") Many areas the stations say 10% but often has less to much less E for many reasons.
E15 to E85 is for "Flex Fuel" vehicles. Station Pumps w/ them should tell you this. Don't use them on any vehicles w/o this "feature" or Can "eat" fuel system parts
Yes, Non Ethanol Gas is rare or Regulated in many places. Example: Some areas only have this at Marinas for boat use. They often won't sell for other uses, more so for cars/trucks because doesn't have Road Tax etc. and often dyed red or purple. If caught having Dyed gas in road cars is often a big problem w/ State's "IRS" equiv getting big Fines and even Jail Time.

The gasoline pumps in my state (NJ) say that the gasoline COULD contain up to 10% Alcohol. Only well to tell for sure is to buy a test kit. You may be getting pure gas or E10.

I stand by the e15 statement. The only concern is emissions and other related fuel injection performance, which is more than capable of handling the e15. From a corrosion standpoint, there are no differences between e10 and e15.

Ethanol is hygroscopic, which means that ethanol attracts and absorbs water moisture. Ethanol mixed gasoline fuels (E10, E20, E25, and E85) can readily absorb over 40 times more water than non-alcohol gas.
Ethanol’s affinity for water means it acts as “dryer” because it readily absorbs water and holds it in suspension. This also lets it act as a fuel antifreeze in cold weather climates.
We switched to E5 and E10 gas here (from whatever it was before). I use E5 because Dutch motoring organization ANWB has warned E10 is not suitable for cars built before 2000.
But you're saying E10 is fine to use in our Fieros?
Ethanol is the same as alcohol. Ask any engine builder what alcohol can do to the inside of an engine, particularly the rings and cylinders. Also, ethanol eats traditional rubber lines and seals as those found on older cars like the Fiero. As a drag racer, I know this well.
I will only use what comes out of a typical pump on my late model daily drivers. Ethanol free goes in all my old cars, generator, lawn mowers, and related yard tools.

Yes, read Fiero Owners Manuel etc. But for you and how rarely you drive, stay w/ E5 or strait gas. Get tank full if you think won't drive enough in next few weeks.
E5 and E10 in the EU maybe more accurate and = to 5% and 10% in most member countries.
Again, US Station Pumps may say 10% but "up to 10%" Ethanol is more accurate in most to all markets.
Actual Ethanol added is done (mostly) at "local" Fuel Distributors to comply w/ local EPA fuel blend rules. Besides most areas have "Summer" and "Winter" gas blends.... EPA and/or States orders blends for an area. Currently 9 "bouquet blends" across the US. (Down from ~ 21 EPA fuel blends a decade+ ago causing "gas shortages" in some markets.)
US "Fuel Markets" may cover a Region, a State, or even a City for EPA and State rules and part or all is the US Federal Clean Air Act and rules that EPA made after. Example: SE PA including Philly often Fails to meet Fed Clean Air rules and Fuels are made to different specs then more rural areas of PA. So SE PA might get X blend but other parts of PA might get Y even Z blends that's often cheaper to make. (not that you see in Fuel prices at the pump because PA High Fuel Taxes etc.) NY and some others have similar setups. But Most to Entirety of DE NJ and others often Fails to meet Fed Clean Air rules because of I95, I295, US301, NJ Turnpike, etc. on top of whatever local traffic plus business and home emissions affects even the rural areas.

Seems when storing a vehicle it would be good to run some Ethanol free gas through it too. Thoughts?
Good question, in the link I posted it seems there is good and bad to both fuels, my main concern is winter storage.. However I don't think any harm will come with E free gas, anyone think otherwise ?
