"But if you have a valuable classic car, it is safest to stick with the gasoline it was designed for."
Doesn't make any difference if the fuel is "hydroscopic", as you say, or not. Water, usually, enters a fuel tank due to temperature hanges. Drain the tank for storage.

Hello CORNHICK , Don't worry too much about being confused on the complexity of using ethanol. Most everyone appears to be including myself.
First off, unless something is designed for particular fuel, you should expect some probllems with it. Ethanol is hydroscopic, so it will absorb moisture. The moisture can be a catalyst for corrosian. I don't thinkg 10% ethanol by itself is corrosive to iron or steel. It might be to aluminum.
Chevron has done lots of research on all the common fuel mixtures.
But if you have a valuable classic car, it is safest to stick with the gasoline it was designed for.

No more than 10% should keep the corrosion at bay if you are running the vehicle every day or so. If you let the car sit for a week (assume your a student that doesn't drive everyday) you should stick with straight 87.

If you look up any Rubber, AKA elastomer, Chemical Resistance Charts you will learn that you got it backwards. The common chemicals in gasoline like: Benzene, Naphthalene, Toluene, and Xylene are very bad for rubber, while Ethanol is compatible with different types of rubber.
You can thank chemicals in gasoline for your "dry and brittle" "older seals".
Example - Rubber Chemical Resistance Chart
Ethanol is also rated "Good" for its chemical compatibility with Aluminum.
Material Selected: Aluminum
Chemical: Ethanol
Compatibility: B-Good

And yet those of use that used E10 in 1976 model cars as far back as 1981 somehow had no problems with damage.
Come on, if you haven't figured it out by now, after over 30 years, give it up, you never will figure it out.

The gasoline currently on the market will not hurt the engine in that car and you cannot find ethanol free gas to my knowledge.

use regular 87 . only cost you $2.50 dollars more in a 25 gallon take to use 87 than 89. and it will be better on your car in long run.

Your going to have to stay away from these new fuels. They dont have the umph that you need. Check your owners manual to see what octane you can safely run.

Fascinating stuff. An entire fuel system replacement on a 43 year old car?
Sounds like an incredibly good parts saleman was involved. Could the problem have been the 'corrosive effects' actually loosened up decades of collected particles and let them finally slide through the system?
With the extent of parts replaced, I'm surprised that the transmission, timing chain, and turn signals all didn't fall prey to the shock of 'this junk'.

"I just had to replace the entire fuel system, from tank to carburetor, on my '69 Dodge due to the corrosive effects of this junk."
Right, old age had nothing to do with it. That is why there are no junkyards with rusting hulks, everything lasts forever! LOL!!
Fuel tanks are exposed under the vehicle. Most of them rust out from road salt, or are damaged by rocks, bottoming out, or various other causes. And they have been making replacement tanks a lot longer than they have been making ethanol.
And if you hadn't rebuilt or replaced the carburetor on a 1969 vehicle by now, it had to have been running pretty badly for a long time, there was no way the original float wasn't saturated many years back.

And what makes you think that ethanol caused this problem? It is a well known fact that there are other common components of gasoline that causes breakdown of gaskets, seals, and fuel system.

Ethanol, also called ethyl alcohol, pure alcohol, grain alcohol, or drinking alcohol, is a volatile, flammable, colorless liquid. In fact, ethanol will dissolve build up carbon as it burns, so the end result is a clean engine. Ethanol also attracts water so it will remove water from your gas tank during condensation in the winter months. E10 is fine for your typical vehicle. You should only be concerned if concentration of ethanol is greater than 10% (E10). Since Ethanol attracts water, you get a greater chance of contaminating engine oil during blow-by. Blow-by occurs when the explosion that occurs in your engine's combustion chamber causes fuel, air and moisture to be forced past the rings into the crankcase. When oil is contaminated with water, oil breaksdown quicker and will cause corrosion to engine parts. Blow-by is usually accentuated during engine acceleration.
Engines with bad piston rings will experience more blow-by. Nowadays, blow-by is remedied with the PCV system (positive crankcase ventilation). At a certain pressure, the PCV valve releases fumes back into the engine combustion chamber to be reburned. A PCV valve should be replaced every 15 to 60 thousand miles depending on the make and engine you have. A PCV valve is cheap to replace (usually less than $1) so make sure it is working fine.
One way to prevent water contamination in your gas is to keep your tank full to avoid moisture absorption from the air inside the gas tank. Make sure your gas tank tightly sealed from the outside air.
Advantages:
Domestically produced, reducing use of imported petroleum
Lower emissions of air pollutants
More resistant to engine knock (higher octane rating)
Added vehicle cost is very small
Non-toxic, biodegradable
Cleans combustion chamber
Disadvantages:
Can only be used in flex-fuel vehicles
Lower energy content, resulting in fewer miles per gallon
Limited availability
Currently expensive to produce

My recent experience with E10 has been poor. And we have no choice, it is all that is sold in gas stations in Connecticut.
I just had to replace the entire fuel system, from tank to carburetor, on my '69 Dodge due to the corrosive effects of this junk. Plus my standby electric generator has started to leak fuel due to cracked rubber seals.
If I had a choice, I would not use E10. Other bad thing is that it reduces MPGs. Who needs that these days?

Nice move CORNHICK. A bit hard to do but I think you've gone a long way to fill in the hole you dug for yourself. I expect that you have also impressed more than a few people with your simple words.
We have many "experienced" contributors here and you'll discover that they offer insights that can only come with the miles and years they have collected so a level of respect for their contributions is absolutely necessary.
With a lot of luck, you will be with us long enough to become one of the multi-millionaire point contributors out there and offer the wisdom that can only come from gathered experience and also the effort to try to help others by passing on what you have learned. Good luck out there.

If you're a college student, then you should know that doing research is much better than relying on the opinions of others. Start with whether ethanol is more corrosive to 2000 era automobile parts than gasoline. Then research whether gasoline and ethanol blends have corrosion inhibitors. I think you'll learn that you will be wasting 12c per gallon if you buy the 87 octane fuel.

I have been driving more than twice as many years as you have been alive, and have probably spent more time servicing automobiles, my own, my dad's, my brother's, and my wife's than you have spent behind the wheel.
I have been using E10 in various automobiles since 1981, every regular pump in Manitoba is E10, but, yeah, what would I know?

Well, the 1976 Valiant I inherited from an aunt lasted a LONG time, had no problem with E10, and the engine never suffered damage, was never touched other than oil changes and tune-ups in over 25 years.
