I don't believe that Chevrolet (or any other) car Dealership has any such expertise. If they were asked a technical question, such as mentioned, and they actually followed-up, they would likely refer it to a Zone office or other available "factory" resource available to them.

please I am tired of reading a million articles about using 10% ethanol gas !! There is absolutely nothing wrong with using ethanol gas Simple solution DRIVE THE CAR !!!! Most of all the people that have problems with ethanol gas are the people who put their cars to sleep for long periods of time or for the winter (6 months ) and wonder why come spring they have all sorts of of problems.. People are like sheep they will follow and listen to what others say without absolutely no proof of theory.. If you live in an area that uses salt on the roads than yes I would wait for a good rain to wash it away. However if the roads are clear fire her up and drive the car ..heck have spoken to some corvette owners and they said they will not drive there car because it’s too cold out ..😳😳 .. you guys treat these cars like they were never abused and driven. I Been running 10 % ethanol for over 35yrs in all my classic cars and never ever had one problem with rubber corrosion or anything else related to ethanol gas because I don’t let them sit idle for months and look at them in the garage. The gas is never idle for long periods of time . I can guarantee you come spring you will see a 100 posts about carburetor problems , wheel cylinder's leaking, gaskets leaking blah blah blah . DRIVE YOUR CARS often , even if you just start in the garage for 20 minutes it better than looking at it with a cup of coffee !!!!!! Your car will thank you
Great to have choices. You can choose to run E10, and I can choose not to for reasons that are valid for me/us.

Re. post #13.... Mel,
According to the website I researched,
"The boiling point of regular gasoline is typically within a range, with the initial boiling point around 122°F to 158°F, while a 10% ethanol fuel mixture (E10) will have a slightly lower boiling point due to the presence of ethanol, which boils at a lower temperature than most gasoline components."
If I recall correctly, the difference is about -9*F. The 'base' gasoline used will have a specific boiling point, depending on additives, etc. Adding 10% ethanol to that same fuel will reduce the boiling point of the mixture.

You mean search engine Google lied again?
Anyway, the point is, run the corn recipe. No sense being paranoid and unnecessarily spending extra cash on Ethanol Free. (unless it's the last tank before storage)
Long term storage is the main issue with corn squeezin'. And that is why I learned to never store a vehicle with a full tank.
The sooner you get fresh gas in the spring, the better off you are.

I would love to purchase 94 octane non-alcohol gas. But none close to me. Since I use Marine Stabil for my outboard, I use it in the Corvette too. Hopefully it prevents damage from the 10% ethanol.
I went to the Stabil website. They sell STA-BIL®Storage, STA-BIL® Diesel Formula and STA-BIL® Marine

Not C3 related but, when I had a cuddy-cabin boat, I used Stabil for winter storage. It had a huge tank, maybe 35 gals.
In the spring I would start the boat on the trailer with the stern drive immersed in a barrel of water.
It quit. Would not start either. Had a SBC with a Quadra J.
Pull the fuel filter and it was coated not only in pink, but strands of fiberglass too. Completely plugged. WTH? The gas tank was fiberglass.
I had a hell of a time getting all that fiberglass residue out of the fuel system. I figured the Stabil ate the tank, eroded it, whatever.
Never used it again. Switched to Lucas Anti Ethanol-Safe-Guard.
