I've been running E10 for almost 20 years in carbureted cars with no issues.
For awhile in the 90's; locally e10 was sold 'seasonally' (in the winter) with non-ethanol sold the rest of the year. The ONLY difference was the e10 cost more, and provided less MPG. Performance? I noticed no difference.
The e10 I now run in my '63 Impala will 'evaporate' faster than non-ethanol; leaving the carb bowl dry after about a week. No big deal to me. It just takes s few more brief starter bursts to start the engine.
Me? I'd use the least expensive fully functional alternative.

I try to run no ethanol fuel in my El Camino because it does not get driven as much as I'd like. Ethanol fuel attracts water out of the air. But around here, the no ethanol fuel is unbranded and is not considered a "Top Tier" fuel so I usually supplement this fuel with a jug of Chevron Techron, BG 44K Platinum, AC Delco X66P or anything from Berryman's.

Lord, this has been beat to death We have had nothing but E10 gas available at the pump in my area for close to 30 years. I simply have not had a problem with it in anything that I own. My daily driver 84 S10, my Wife's 84 Riviera that was driven daily until she retired a year or so ago, all of my lawn equipment etc. In my opinion a big factor is the brand of fuel you use. I use 87 Octane Shell almost 99% of the time.

I bought a new (Returned) lawnmower 3-4 yrs ago that someone had used eth gas in and it screwed up so the person brought it back to Lowes, they sent it to their factory auth. repair and they replaced the carb gaskets (what the Lowes manager told me) then had it marked down pretty low, well enough for me to buy something that says Honda on it lol, maybe my carb stuff sits too much for eth gas

Only issue I have seen is long term storage the fuel can separate. As far as day to day use? no issue. I'm sure possibly over 10 years or more there will be increased erosion due to the ethanol, but not enough to make a difference. My suburban is 15 years old, has only run on ethanol gas and sits for 2 weeks, sometimes more at a time between uses. I just lost the fuel tank sensor a week ago.
That's a 2006? It's fuel injected with an electronic fuel pump, plastic/stainless fuel lines and connectors designed for alcohol, stainless injectors, and 58psi @ the injectors. Carbs use atmospheric pressure and suction to deliver fuel. Carbs are also bare aluminum casting. Ethanol/alcohol is hygroscopic, it absorbs water. Water and bare aluminum do not mix.
The E10 debate may be due to fuel blends in certain states/areas? I can't tell you how many neighbors/strangers lawn equipment I've had to clean the carb due to E10 choking them out.
Highest octane rating for non-ethanol I've found around me is 89 and I'm at the east coast hub for the pipeline!
If the car sits more than 2 days, I would advise against running ethanol blend. I only use non-ethanol and Stabil in my lawn equipment. If you're running rubber hoses, check to see that they're rated for alcohol/blended gas.

I use the Marine Grade Stabil if my vehicles sit for any length of time. It's supposed to remove the ethanol.

That's the problem I have with it, then trying to blow the cobs out after finally getting it started. As long as I drive it every day or two its okay.

I run non-ethenol when ever I can. I spent the winter repairing and replacing small engine carbs and fuel lines, do not need that in my cars and boat. I can find it easily at local stations.

it seems to me i remember reading about the detrimental effects of ethanol on rubber parts.
that brings me to another thought. tanks full or partial for long term storage?
Ethanol free for me in all my small engines, dirt bike and atv. And my Cutlass.
