Most of finished motor gasoline sold in the United States is about 10% fuel ethanol by volume.

Very first sentence. 'About 10%' is not the same as 10%, and 'Most' means not all gasoline is 'about 10%'. You can still buy ethanol free gasoline.

That's why it's phrased as "May contain up to 10% ethanol." Without testing a sample you won't know exactly how much ethanol it contains.

    About 10% is not the same as 10%

    That's correct, using EIA's numbers, it's actually 10.12% ethanol in 2023!

    Math: 0.33b / 3.26b -> 10.12%
