A recent report from GasBuddy indicates that Mondays offer the lowest average gas price in most of the United States.
That follows the trend of GasBuddy’s research for the last several years. To come up with the data for its latest report, GasBuddy says it analyzed fuel prices from the GasBuddy app from January 1 to December 16, 2021.
In the new findings, GasBuddy says it found that Thursday is the worst day to buy gas in 28 states, and Wednesday (the worst day in 16 states) is the second-most expensive day.

“Though there is variation in daily gas prices across different states, the consensus is that filling up at the beginning or end of the work week, on Monday or Friday, is the best way to save money,” Patrick De Haan, head of petroleum analysis at GasBuddy, says in a news release. “Following Monday, Sunday is the cheapest day to fill up. But even if you can’t always time your fillups, the golden rule is to always shop around before filling up.”
