SO !!!!.  Here in the northeast we have made peace with it.  Very few to no places to get non-ethanol fuel.  Just make sure the car is prepped for it and away you go.

Very happy there's a Buc-ee's 10 minutes down the road that sells 90 octane non-ethanol. The 57 just loves that stuff!

It helps to have compatible plumbing. I also use Sta-bil. If your vehicle sits for long periods, you might also consider draining the carburetor.

If this becomes common practice, I think there will be the need for some carburetor rejetting. I tested fuel last summer and found just under 10% ethanol here in louth east Michigan..............https://www.epa.gov/renewable-fuel-standard-program/final-rulemaking-modifications-fuel-regulations-provide-flexibility

Further to Blacktie's post re fuel stabilization.. To stabilize for Ethanol " specifically",  use a product like Staybil "360" which is designed to mitigate it's effect on your fuel system.. There may be other similar products, but I don't have info on  them..

I’m stuck with ethanol blended gasoline in Taxifornia; I’ve been using Star Bright Star Tron enzyme additive for 8-10 years in my 56. In 10,000 miles I’ve not had a fuel related problem. I’m sure the gasoline in the carbs evaporate over time; if I drive the car once a week it’s one pump and start. 2 weeks it’s 2 pumps and a month takes at least 20 seconds of cranking. I use 1oz with 10-12 gallon fill up.

D. L. Racer: If after a month or so your car is very slow starting, & if you have some Lawn mower fuel or other available. Try removing the Air cleaner cover & carefully pour say 1/2 to 3/4 once of fuel in the carb venturies.  That should get the engine to start briefly & pump up some fuel to restart if needed..

Here are some early morning thoughts on the subject.

Using 19000 BTU/lb for gasoline and 12500 BTU/lb for ethanol, you end up with a 3½% reduction in energy at the 10% ethanol content levels.  If using 45 MJ/kg for gasoline and 25MJ/kg for the energy density of ethanol, then at the 10% ethanol content you lose 4½% of the energy density.  With a reduction in energy content, there will be a reduction in the fuel economy per gallon.

Supporting this was my 4 cylinder Ranger pickup that typically lost 1½-2 MPG when using the 10% ethanol blended gasoline versus non-ethanol blended gasoline.  While I have not run any ethanol versus non-ethanol tests on my 272 Y, it has seen a decrease in the fuel mileage since the premium fuel I’m using has gone from zero ethanol to 3-5% ethanol.
