The PBS news had a blip about the USA upping ethanol to 15% to cut fuel costs a few cents US per gallon. They implied it may hurt air quality and IMO the odor from the B.S. is the biggest factor in the air quality. What about future costs to motors?

15% ethanol coming?

Not for Canada - not yet. 15% Ethanol doesn't like cold weather starts, so that rules out most of Canada.

Many Ford products are rated for E15.
Can’t say I agree with that option much as it lowers fuel economy.

Flex fuel vehicles have been around for a long time.
Is cost per mile ever calculated? Imagine if they went metric and less is better.
Ethanol is "half burned" compared to regular hydro carbons (alcohol molecules are Hydrogen, Carbon AND Oxygen)... less energy per volume.
So the question is, will the lower energy content of the extra Ethanol offset any savings in the cost per gallon. Could be a false savings....

All that matters to the average Joe is the price the pump says all the other stuff is just noise.

Yup. Another government turd. Rewarded car makers for making vehicles compatible with E85 but afaik, you basically can't buy E85 in Canaderp. Maybe a literal handful carry it.
Edit:
Anyone know details about flex fuel branding? I assume they dont bother with an ethanol sensor and just lose a bunch of power when running on e85? The only people I know that run e85 are using it to make power and they need to upgrade fuel pumps, injectors and ideally add an ethanol gauge to try to avoid blowing it up.

How can I compare the energy content of alternative fuels and gasoline or diesel? - Greater New Haven Clean Cities Coalition
…What implications does this have for overall fuel and vehicle comparisons? Alternative fuels have varying energy densities and are measured using a number of different units, which can make […]

gasoline 116090 BTU gallon
Ethanol 76330 BTU gallon only 65% of the energy
A gallon of 15% should have 98676 BTU from the gas and 11449 from the ethanol = 110125 BTU but if you mix gas and ethanol the individual quantities don't equal the combined quantity because of molecule size. To get a full gallon one has to start with more than the 85% and 15% of a gallon so theoretically the BTU content of a measured gallon of E15. Now they can advertize concentrated fuel.

If you only get 75% of the energy per gallon do you only pay 75% of the taxes?

What you need to know about E15 fuel - Hagerty Media
Ethanol-blended fuels like E15 are not new, but their availability during the summer months is. Learn the pros, cons, and when to avoid E15.

I think it's the same C2H5OH.... the only difference is the mix.
I think people would be complaining a lot less if we could get e85 for a few $/L and it didnt have methanol in it.
