Gas is least expensive on Sundays, according to a new study.
GasBuddy released a new analysis detailing the cheapest and most expensive days of the week to buy gas in all 50 states. Sunday is consistently the most affordable day, while Wednesday through Friday tend to be more expensive.
Weekly Patterns
Oil prices can fluctuate with seasonal demand, but weekly patterns remain consistent. According to the study, “In most states, prices gradually rise through the week before easing into the weekend, creating a reliable window for motorists to save simply by adjusting the timing of their fill-up.” It is estimated that buying on the lowest-priced weekday instead of the most expensive one can save drivers 4 to 9 cents per gallon.
Price Cycling
In several states, including Texas, Michigan, Indiana, Ohio, and Florida, prices follow a more pronounced pattern. Known as “price cycling,” prices can reset higher on a specific day, then slowly decline over the next several days before the next spike. In these states, the best savings come five to seven days after a price jump. The difference between buying at the peak of the spike and the end of the cycle can be 15 to 45 cents per gallon or more.
Methodology
GasBuddy offers a full state-by-state breakdown of the cheapest and most expensive days. GasBuddy arrived at these numbers by analyzing daily statewide average gasoline prices over the past year and normalized prices within each week to identify patterns independent of seasonal trends. These savings don’t account for any additional discounts.
Takeaways
What drivers can take away from this data is that it can pay to wait. Planning a trip to the pump can result in unexpected savings. If gas prices are a top concern, consider a more fuel-efficient vehicle and the grade of gas your car needs.
