Cheapest Days of the Week to Fill Your Tank (Backed by Data)

If you’re a driver, you’re probably always looking for ways to save on fuel. The good news is that there are patterns in fuel prices that can help you time your fill-ups for maximum savings. Research and data have shown that the price of gas fluctuates throughout the week, and knowing when to fill your tank can make a big difference in your fuel costs. In this post, we’ll dive into the data-backed trends on the best days to fuel up and how you can use this knowledge to save money.

The Impact of Gasoline Pricing Patterns

Gasoline prices are influenced by a variety of factors, including supply and demand, market conditions, and geopolitical events. However, one of the most significant influencers of gasoline price changes is the day of the week. Studies, such as those by GasBuddy, have shown that fuel prices tend to follow predictable weekly patterns. Knowing these trends can help you plan your fill-ups and avoid paying premium prices at the pump.

Best Days to Fill Up Your Tank

According to data from GasBuddy and other fuel price tracking websites, Monday and Tuesday are typically the cheapest days of the week to fill your tank. Fuel prices tend to rise starting mid-week and peak on Friday or Saturday. Here’s why:

  • Monday and Tuesday: Gas stations are often eager to clear out older inventory before they receive new shipments, which can result in lower prices. Additionally, many stations set their prices early in the week to stay competitive.

  • Wednesday and Thursday: Prices often start to rise around Wednesday, as stations begin adjusting prices to reflect the upcoming weekend’s demand.

  • Friday and Saturday: Gas stations typically raise prices in anticipation of weekend travel, as demand tends to spike during these days. This is when you’ll find the highest fuel prices of the week.

Why Fuel Prices Follow This Pattern

There are a few reasons for this price fluctuation:

  1. Demand: Demand for gas is typically higher at the end of the week as people prepare for weekend trips, making fuel prices more expensive. Conversely, the beginning of the week sees lower demand, leading to lower prices.

  2. Supplier Adjustments: Gas stations adjust their prices based on their supply levels. At the start of the week, stations may have more fuel in stock, allowing them to offer lower prices. By the weekend, fuel supplies can be low, prompting price hikes.

  3. Competition: Gas stations often monitor each other’s prices and adjust theirs accordingly. Early in the week, there’s less competition for price hikes, while by the weekend, stations will price higher to take advantage of increased travel.

Using Gas Price Apps to Your Advantage

To take full advantage of these price trends, consider using gas price apps like GasBuddy or others that track real-time fuel prices. These apps can help you identify the cheapest gas stations in your area, and many even offer price forecasting to let you know when prices are expected to go up or down. By monitoring these apps, you can plan your fill-ups on Mondays or Tuesdays to avoid paying more later in the week.

Additionally, apps like GasBuddy allow you to filter gas stations based on distance, brand, and current pricing, making it easy to pinpoint the best deal before heading to the pump.

Final Thoughts

Understanding the weekly fluctuations in gas prices can make a significant difference in how much you pay at the pump. By filling up on Mondays or Tuesdays, you’re more likely to avoid the higher prices that often hit later in the week. Armed with this knowledge and the help of price tracking apps like GasBuddy, you can make smarter decisions about when to fuel up, helping you save money over time.
