They do make plenty of products to remove water from the gas but they shouldn’t be used continuously.

We have 10% ethanol in all our gas here in MN and there are a very large number of stations already offering E15. They are selling it as 88 octane for less than the 87. The average Joe will have no idea what they are buying. I have a diesel truck so easy for me to avoid and I have trained the wife In well on the ethanol subject. Along with that we still have plenty of 92 non-oxy (ethanol free) pumps around, almost every station. The recreation vehicle use in MN is keeping that alive.

I can't tell if you have mods done to your motor that increase its tendency to have pre-ignition/knock. (high comp pistons, turbo, supercharger are things that would.) So really, it might not require that high of an octane rating.
I know when people run e85, they end up having to inject vastly more fuel to match their AFR and power compared to pure gas but it does allow more tolerance to knocking. So potentially, yes. You would need larger jetting to maintain the same power and AFR. With e15 it might be fractionally larger but...

60 % of mower/ chain saw shop business is repairing alcohol damage!!!

About a year ago, I asked a mower shop service guy about damage from alcohol/gasoline effects.
He stated that 60 % of his shop income was from repairing alcohol related damage.
I know porsches are not infrequently used yard equipment, but, if you don't keep the "fuel" constantly moving through the system, you could have some expensive repairs coming soon.
Personally, I am looking at cleaning" up a 6 year, "idle" fuel system.
"F" alcohol.

Another reason to ditch your archaic carbs and CIS.

Update your engine to EFI and better yet, ITB's with EFI to get the most of your motor!

911 engines were not meant to be stifled by CIS and run poorly when cold with carbs! She deserves better than that!

I have 93/95/100 octane available for my Hot Rod.... it's expensive but worth it. Thank goodness I only burn a tank about once a month.

In any case be careful with this stuff! My son races an Ultra4 unlimited class off road racer with a supercharged LS3 in it. It's set up for E85. We have a test kit and typically buy our fuel 55 gallon drums at a time. We test each batch and have found the alcohol percentages all the way from 60% to 90%! So, the tune has to be adjusted pretty much each time we buy fuel. I can't imagine that E15 is going to be any more accurate, so I worry about what happens when you get a batch that just happens to be well above 15% alcohol!

I live in Wa state and just filled the SC yesterday with ethanol free gas and it came to $72. I almost fell over. Haven’t seen prices that high for 10 years when filling my Audi came to $75 and the gas pump shut off at $50 and had to reinsert my credit card for the remaining gallons.

$72 is high but rationalized it as good insurance.

Any other states restrict road use fuel to "E" fuels??

In humboldt county, kalifoania, any purchaser of alcohol free fuels must sign a verification that absolutely none of that there non ecogroovy fuel will NEVER, ever be used on public roads, no how, no way...
AND, they ream you $5 bucks and change for it.

Assuming mix consistency can EFI return performance equivalent to real gas?

I have a few options locally to get ethanol free gas. It's 25-30% more expensive than "regular" gas so if I know I'll be driving a bunch I opt for the corn infused, if the car will be sitting for a while I get the ethanol free.

This stuff was recommended by a Porsche tech friend. It is said to remove (or neutralize, not sure of the chemistry) the ethanol from gas. One ounce per 20 gallons.

I use XP3 in both Porsches especially when the carbed 914 starts to act up. Also use it as n my diesel and A6. Good stuff. Usually every other tank full
