I'd be surprised if you could really tell the difference. I would suggest fuel stabilizer for storage times.

I get 2-3 MPG worse with E10 vs E0.

Your fuel hoses may need changing unless they are recent.
Likewise the diaphragm in your fuel pump if it has one.
And the gaskets in your carb. I had to rebuild the Holley on my Rambler.

The FBHVC has published some recent thoughts here [fbhvc.co.uk] which are worth reading.
Inter alia, they say Ethanol contains approximately 35% oxygen by weight and will therefore result in fuel mixture enleanment when blended into petrol. Petrol containing 10% ethanol for example, would result in a mixture-leaning effect equivalent to approximately 2.6%, which may be felt as a power loss, driveability issues (hesitations, flat spots, stalling), but also could contribute to slightly hotter running. Adjusting mixture strength (enrichment) to counter this problem is advised to maintain performance, driveability and protect the engine from overheating and knock at high loads.
Adjusting mixture strength is very easy on SUs of course, not so easy with fixed jets which generally don't have adjustable air bleeds for intermediate and high-speed.

I always use Super grade which is and fttb will remain E5 or even E0.
And I routinely use an additive, Castrol Valvemaster or the like which is anti-ethanol plus octane boost.

My car has been sitting three months since I broke a bone, it now has half a tank of somewhat stale fuel.

The hoses are the largest worry IMO
The only fuel hose I use now is gates barricade. Not the cheapest - but a lot cheaper than the excess (deductable) on a claim...

I used e10 after my engine swap and neglected to consider the cleaning of the fuel tank.
I soon clogged the 10 micron filter to my fuel injectors. I replaced all the fuel hoses with teflon
lined and gates barricade. I have one piece of ďall fuelĒ braided covering hose in the engine bay,
and can smell fuel if I get close to it. All gasoline has changed since the 70ís and earlier.
Iím currently visiting in Michigan, and non-ethanol gas is hard to find.

Thanks Carl! It turns out there was a Murphy station near our hotel.
In Detroit for the Woodward Dream Cruise. Iím kinda out of my comfort zone among
All the muscle cars-and new Mustangs and a Hellcat or two. Why they never get a ticket
For noise is a mystery. Plus, everyone on the freeway drives like they are escaping
Armageddon!
