Ethanol gas question

Group, As we move closer to winter time, here in the Midwest, my 2011 Rouchcharged VMP tuned Mustang will be sitting a lot when the snow does fly, so question about fuel.
We do have a gas station here that is not listed as Top Tier, but they do sell 91 octane with no ethanol. I know that Ethanol absorbs moisture, so I am thinking to use the 100% Gas for winter with the long garage times would be better than a Top Tier gas with 10% Ethanol.
Actually car seems to like the 100% Gas, so may run it year round, But them not being listed as Top Tier make me a little nervous.
It is a Cenex Station and they do advertize the No Ethanol gas, but I don't know what additives they put in the gas.
Opinions! Thanks


Wow, This 2011 Stang is FAST.

Why not get the one with ethanol and add a fuel stabilizer? That's what I do. No problem for me

" I know that Ethanol absorbs moisture,"......I hear this statement often, but it raises a couple of questions in my mind;
How exactly does moisture get into the fuel...especially if you use a lockable tank neck cap? OR is ethanol in itself a water based fuel? Any links explaining this would be greatly appreciated... for the record, I have used nothing but SHELL 91 since day one, According to info posted on their pumps, Shell 91 contains NO ethanol... the silver (midgrade) says up to 5% ethanol, bronze (regular) up to 10%...

The rest is all FORD

I think it stems from the actual stations, not the cars. I know most marinas don't have ethanol fuel because of this. I imagine maybe the plates that cover the wells aren't exactly the best seal.

From the gas supplier's underground tank. And moist air in your car gas tank condenses ...like cold moist air in the winter on single glazed windows.

Might want to consider a well-proven octane booster. Finding the right one that gives the benefit without the drawbacks is the issue. Seems like klotzlube and toluene are generic ones worth reading about. Some links:

Which octane boost is best? | Fuels and Fuel Additives: Gasoline and Diesel | Bob Is The Oil Guy

Best OCTANE BOOSTER????? - Corvette Forum (see post #5)

Fuel Rating - Octane Comparison - Dyno Tests Graphs - Hot Rod Magazine

I've heard both good things and bad things about Torco... Depends on engine, forced injections, tune, be careful

Torco Accelerator - It's not just an octane booster

There is no good octane booster... So you are going to tell me one pint of something is going to raise 15 gallons of 93 to 101?
If I used 104 octane gasoline it would take roughly 35 gallons of 104 to make 15 gallons of 93, 101 octane... so no there is no octane booster in a pint can.

I don't speak often but when I do, I don't have clue what I am talking about. I just repeat things that I once heard and do not repeat them correctly... My doctor told me it was an ID 10 T problem and it was incurable.
So when I reply to a post or add to a thread I just find the words elsewhere and copy and paste.
