Those two things sound impossible together. They happened anyway, and the reason is a number most people never look at.
In 2025 Americans drove 1.2% more miles than the year before — but used 1% less gasoline, averaging 8.9 million barrels a day.
Basis: U.S. Energy Information Administration, “Increasing fuel efficiency leads to decreasing gasoline consumption” (April 10, 2026)
The missing piece is fuel efficiency: how far a car goes on the same amount of gas. It improved 1.9% in 2025 — more than enough to cancel out the extra driving.
Basis: Same EIA article
Compared with 2019, gasoline use is down 4%. EIA expects it to keep falling through 2026 and 2027, as fuel economy keeps improving and the growth in miles driven slows down.
