Aside from a slight bump in the summer, US gasoline consumption has been on a steady decline. There was a rapid decline in the spring when gas was near $5/gal with the summer bump being the weakest since 2008. The shift to hybrid and electric cars is part of it, but a lot of it is people just aren't driving as much they usually do.
US gasoline consumption hit a peak of 9.7 million barrels a day in September 2019 before falling off for the winter slump. It tanked to 5.7 million/day in 2020 due to lockdowns, which drove prices down to well under $2/gal. It recovered to 9.5 million/day peak in summer 2021 and has been on a decline ever since, currently at 8.6 million/day. Supply has been as much a rollercoaster as the demand, especially this year.
The last time I checked the ethanol content of premium pump gas here in SC was about a month ago, and it was right on 10%.
