ethanol-free gas station List

All Phillips 66 gas stations sell ethanol free 91 octane here in Des Moines. Its nice because they even have separate fuel hoses for the 91, so you can be sure that there is no ethanol residue in the hose from a previous customer. BTW: None of the Phillips 66 stations are listed on that site you mentioned.

We use ethanol free gas in our boats and our personal watercraft.
I've used that site before in the past, and it was fairly accurate and useful.
Now we just go to the same places every time, so no more searching.
The stations we use offer it year round, specifically for their clientele.
They know it's hard to find, and they charge a significant premium for it.

My experience around here has been that it's not any one particular brand.
It's more like specific stations that have just chosen to carry the ethanol-free formulation.
They're usually around the lakes, because it's popular with boaters willing to pay the premium.
And there's no easy way to confirm if it's actually ethanol-free, other than to trust them.
Whenever I'm pumping it, I sometimes wonder if I'm really getting what I'm paying for...

Phase separation where the alcohol/water mixture ends up on the bottom of the tank is the problem and once it separates it is basically irreversible ! Some additives help delay it but most 2 cycle engine makers recommend never using gasohol stored for more than 30 days !!
Alcohol washes down the oil film that is needed in a 2 stroke for LUBRICATION a very bad thing. So the marine environment where water is ever present and fuel can sit around for longer periods of time.....makes it a big problem. Real synthetic oil (ester based) not the highly refined petroleum based stuff now legally being sold as "synthetic" is said to NOT be washed down as easily but is much more expensive.
Some of the 928s which are seldom driven are obviously at risk of phase separation and you could have a couple of gallons of alcohol/water in the bottom of the fuel tank.

That is very good but sobering information Jim. Especially for those folks who let their car sit. In winter, I always store with e-free. I am lucky as there are two stations within 5 miles of my house.

No so much around here, but I found a Sunoco Station in South Hill, VA (on the way to VIR) back in Novemeber that sells it and doesn't upcharge. $1.97seems like a lot now, but back in Nov, it was not bad at all for Super. Actually, I think it was a little less than the ethanol stuff.

I must be the only 928 owner not overly concerned about this. All my cars not requiring premium have been running 87 with 10% ethanol without any fuel issues, including my 928's which are parked every winter (except the 87 and the supercharged 81, they get premium)
For those who think this is going to rot out your gas tank, consider Todd's twin turbo is running E85 with the stock tank and Bosch 044 pumps.
Other cars we've been involved with converting to E85, the only modification necessary is larger injectors and sometimes a higher flow pump since ethanol is less efficient and requires more fuel.
Carbureted engines? That's a different story and doesn't apply to the 928. I use ethanol free gas for my small engine fleet with carbs.
I think sometimes people confuse ethanol with methanol which will eat through rubber / plastic not rated for its use.

so , is there a power difference with non ethanol gas? certainly, if you need more gas to make it work, that takes the place of air, and that lowers power, so thats no good. wonder if they have this in California... ill have to check that program. (from the link.. nothing near 200-300miles away from the bayarea)

I run 10% in everything. 87 in the motorcycle and 944, 93 in the 928 and Cayenne. M/C, 944 & 928 get a full tank of fresh, along with SeaFoam at the end of the season and get parked for the winter (usually Thanksgiving until April 1st). Oil gets changed too.
I've had the 944 for 10 years now. I don't drive it anywhere near as much as I used to (about 800 miles last summer). If the 10% ethanol was going to cause issues, I'd be one of the first to experience them.
I've mostly given up trying to convince anyone that there's nothing wrong with it. For example, how would it be physically possible to "have a couple of gallons of alcohol/water in the bottom of the fuel tank." It would get drawn out when the car is run. If it was that bad, the car either wouldn't start or wouldn't run for very long.

Nope. I'm the exact same way.

I know what phase separation is. And how it happens. Just about every site that comes up on a google search is "Gloom and Doom" catastrophic failure predictions. I don't see that happening.
It takes over 0.5% water for that to happen. That's over a pint in a 20 gallon tank. I drive a semi with about 200 gallons capacity. I drain the water out of the water separator every time I fuel. It's rarely more than a tiny amount. I'm also a pilot. We drain the tank sumps during preflight inspection. Again, it's rarely more than an ounce or two (maybe 40 gallons fuel capacity).
I probably shouldn't have said "I don't think it's possible."
I should have said "It simply doesn't happen."
A few years back, for several years, I'd drive my 944 almost exclusively during the summer. I'd drive my Chev Blazer the mile or so to work. I'd go to work on Saturday, work all week, come home on Friday and have a week off. So I'd drive the Blazer about 1 mile, once a week. I ended up needing a solar trickle charger because I didn't drive it enough to keep the battery charged.
I'd fill the tank maybe three times all summer long. And I had zero fuel related problems. If phase separation due to water from condensation is a real problem, what I did with that truck would have almost certainly caused it to happen.
As a kind of funny aside, I live where winter gets cold. Water from condensation can get into the fuel lines and freeze up, blocking the lines. Everyone used to use "Heet", which was an alcohol product that would absorb the water and lower the freezing temp of it so there wouldn't be problems. It was typical to put a bottle in every third or fourth fill up. I haven't used it at all since they added ethanol to the gas.
