Thursday is your best day to fill up gas in Oklahoma. According to GasBuddy data, you'll find the cheapest prices on Thursdays. Wednesday is the worst day to buy, so plan ahead and avoid filling up mid-week.
Best Times to Buy Gas in Oklahoma
By Day of the Week:
- Best: Thursday
- Worst: Wednesday
Gas stations raise prices when traffic is heaviest. Since most drivers fill up on weekdays during their commutes, prices tend to spike mid-week. Thursday breaks that pattern and offers a price dip before the weekend rush.
By Time of Day:
Fill up in the early morning or late at night for additional savings. Gas is denser when temperatures are cooler, which means you get more fuel for your money. A gallon of gas takes up less physical space in the morning than it does in the afternoon heat. Gas stations also know most people fill up during the day when they're driving, so they raise prices during peak hours (roughly 9 AM to 5 PM).
Action Steps
- Mark Thursday on your calendar as your regular fill-up day
- Set a phone reminder for early morning (before 8 AM) or evening (after 6 PM)
- Check local prices throughout the week to spot your area's specific patterns, since prices vary by location and station
- Avoid Wednesday when prices typically peak
