ethanol free mix?

So much for trying to find non Ethanol fuel in Long Island. For those in other areas you may want to take a look to see if there is anything local:

What do people use to get rid of the nuisances of this govt subsidized, politically correct, "eco- friendly" formulation that takes away long term Porsche performance?

Sorry don't want ethanol in my mix .....

The owner's manual says that the engine will delay timing if the knock sensors indicate a fuel with sub-optimal octane rating is being used. Wouldn't the same thing happen with ethanol "laced" fuel (e.g. the engine adjusts timing to adapt to the fuel)? Does it really hurt long term engine reliability?

I got excited to see my local gas depot was advertising 'ethanol free, 100% gasoline' only to find the only grade they sold was 87 octane regular. <sigh>

ethanol is an octane booster, so I miss the point here I guess

Ethanol added to bost octane and reduce state taxes is OK in the 10% range, but E85 is a No No.

Ahhh. I see. Is the ethanol itself bad for the engine components, or is the additional octane bad?

Ethanol by its nature is corrosive. That's why the E85/Flex Fuel engines have different, more corrosion resistant fittings.

May want to add a little StaBil Ethanol treatment (blue color) to your gas. I hope it works, I add a little with each fill-up. Keeps the gas sweet during prolonged times between drives as well. There's another brand made primarily for boats you could use as well, I forget the name.

Sta-Bil "blue" is the marine formula. They now market a non-marine version. I use it too.

In layman's terms, ethanol attracts moisture, moisture causes corrosion, and that is bad for any car, lawn mower, boat, etc. After that, ethanol contains less energy a unit than gasoline and therefore using ethanol "enriched" gasoline causes lower mileage. Both reasons are sufficient for me to try to find ethanol free gasoline.

Had a station that sold ethanol free gas until a couple of months ago. Station manager told me refinery quit making ethanol free gas and he, nor any other station, could get ethanol free gas in our area. I'm sad.

I never knew that ethanol "enriched" gas could be bad! Based on Nycarrera's link above, my state is not even listed, so I guess I am in the same boat. Also, I read somewhere that stations sell a "winter mix" that has more ethanol than summer mix. Am I right about that, and if so, what is the reason for adding more ethanol in the winter time?

IWe have ethanol as an oxygenate now because it is less "toxic" than MTBE.

Porsche says up to 10% ethanol is allowable (Page 217, 997.2 Porsche Owners Manual)...

Fuels Containing Ethanol

Do not use any fuels containing more than 10 percent ethanol by volume.
We recommend, however, to change to a different fuel or station if any of the following problems occur with your vehicle:
– Deterioration of driveability and performance.
– Substantially reduced fuel economy.
– Vapor lock and non-start problems, especially at high altitude or at high temperature.
– Engine malfunction or stalling.

Allowable, not desirable.

E-10 does something conventional gasoline will NOT do, and that is keep your car DRY. Your P-Car is warranted to run on blends of up to 10%. You are fine. If you live in CA, you've been putting it in your car for a long time.

The whole "Ethanol" thing is many things, really. It's wasted tax dollars subsidizing its cost (at least for a few more weeks). It's wasted resources devoted to its production by refiners that have to meet minimum production standards. It's a plethora of misinformation and innuendo.

But it's not going to ruin your P-car. Period.
