Gas prices aren’t just about location—they’re also about timing. Just like airfare and hotel rates, gas prices fluctuate throughout the day and week. Knowing when to fuel up can help you avoid price spikes and keep more money in your pocket over time.

This guide breaks down the best times to buy gas, based on data from national fuel analysts and real-world trends, along with some practical tips to stretch your fuel budget further.

When Is the Best Day of the Week to Buy Gas?

According to research from GasBuddy, Monday is typically the cheapest day of the week to buy fuel in most parts of the United States. Prices tend to be lower early in the week and gradually rise toward the weekend.

• Monday – Consistently the cheapest day in most states
  
• Tuesday – Also favorable, but slightly more variable
  
• Wednesday to Friday – Mid-range, but climbing
  
• Saturday and Sunday – Often the most expensive due to increased demand
  

Stations frequently update prices in anticipation of weekend traffic, especially in cities and tourist-heavy areas.

What’s the Best Time of Day to Buy Gas?

Fuel prices can change multiple times a day depending on market trends, competition, and supply. However, mornings tend to be the most stable period for pricing.

• Early Morning (6 a.m. to 9 a.m.) – Stations haven’t yet adjusted for market changes or increased demand
  
• Late Morning to Afternoon – Prices can rise as traffic increases and competitors react
  
• Evening Hours – Prices may stabilize again but are often still higher than morning rates
  

To get the best rate, fill up early before your commute or errands begin.

Avoid Refueling Before Holidays or Weekends

Prices almost always spike around holidays, especially Memorial Day, Fourth of July, Labor Day, and Thanksgiving. If you’re planning a road trip or family visit, fill your tank a few days before the surge.

Similarly, stations near highways and airports tend to raise prices during peak travel times. If possible, plan your fill-up in suburban areas slightly off your route.

Use Tools to Monitor Price Fluctuations

Apps like GasBuddy allow you to track real-time prices and see historical trends for your area. Other useful tools include:

• AAA Gas Prices – Offers state and regional fuel price averages
  
• Waze – Shows user-reported gas prices along your route
  

These tools can help you anticipate changes and avoid overpaying.

Bonus Tip: Save Even More with Digital Gift Cards

Beyond choosing the right time, how you pay also matters. With platforms like Fluz, you can earn cashback with a BP virtual card or get rewards with a Shell virtual card even if you’re filling up during peak times.
