Filling up your tank is a little cheaper this week as gasoline prices drop. The price of regular gasoline in the United States fell to an average of $4.354 per gallon on Monday, October 5, according to the federal government's Energy Information Administration (EIA).
Why it matters: although prices have fallen, gasoline is still $1.23 per gallon more expensive than it was a year ago. For a 15-gallon tank, that's about $18 more than in October 2025.
At this week's national average, filling a 15-gallon tank costs about $65.31, compared with $66.98 last week, a savings of roughly $1.67 per fill-up.
The gasoline prices drop was not uniform across the country. According to the EIA:
The Gulf Coast remains the cheapest region, with an average price of $3.911 per gallon.
Diesel fell for the second consecutive week, with the national average reaching $6.199 per gallon, 18.3 cents lower than the previous week. Since hitting its 2026 high of $6.529 on September 21, it has fallen 33 cents. Even so, diesel remains $2.49 per gallon more expensive than it was a year ago.
