Gas Price Spells: When to Fill Up for the Best Rates
Ever feel like gas prices magically spike right after you fill your tank? While it might feel like bad luck, there’s actual data behind those price swings—and knowing when to fuel up can be just as powerful as knowing where. With a bit of timing and strategy, you can consistently catch the best deals at the pump without needing a crystal ball.
Here’s your data-backed guide to choosing the best days and times to buy gas, so you can fill up without draining your budget.
Best Day of the Week to Buy Gas
According to long-term data from GasBuddy, Monday is often the cheapest day of the week to buy gas in most U.S. states. Prices tend to rise midweek—especially by Wednesday and Thursday—as stations anticipate increased weekend travel.
Why Monday Matters:
- Stations often reset prices after analyzing weekend sales data.
- Demand is generally lower early in the week, reducing the incentive to raise prices.
- Fewer drivers fill up on Mondays, helping prices stay competitive.
Worst Day of the Week to Buy Gas
Friday and Saturday tend to have the highest average prices. This is when demand spikes due to commuters topping off before the weekend and travelers hitting the road. Many gas stations raise prices by Thursday night in anticipation of the rush.
Best Time of Day to Fill Up
Fill up in the early morning or late evening—ideally before 10 a.m. or after 7 p.m. Prices are typically updated during the day, and early shoppers may catch lower rates before daily increases take effect. Morning fill-ups also help you avoid peak-hour congestion at busy stations.
Avoid Filling Up Right Before Holidays
Holiday travel often leads to sharp increases in gas prices. If you’re planning a road trip, aim to fill your tank at least 2–3 days before major holidays like Thanksgiving, Memorial Day, or the Fourth of July. Prices typically rise the week leading up to these holidays and may remain high until demand settles.
Watch for Local Patterns
Gas price behavior can vary by region. Urban areas may see more frequent price changes due to higher competition, while rural stations often adjust prices less frequently but may start at higher baselines. Use tools like the GasBuddy Price Trends map to monitor changes in your state or metro area.
Set Alerts and Track Trends
GasBuddy also lets you set price alerts based on your location, so you’ll get notified when prices drop near you. Their “Price Heat Map” feature shows real-time fluctuations across different areas, helping you decide whether to wait or fill up now.
A Little Timing Goes a Long Way
There’s no need for fortune-telling when data is on your side. By planning your fill-ups for the right day and time, you can consistently score lower fuel prices and keep more cash in your pocket. Fuel up like a pro—not a last-minute panic buyer—and turn your timing into a money-saving spell that actually works.
