Which State Has the Cheapest Gas? Oklahoma Holds the Title at $3.946/Gallon
Oklahoma has the cheapest gas in the United States, with an average regular gasoline price of $3.946 per gallon as of May 11, 2026. This positions Oklahoma approximately $0.038 below Mississippi ($3.984) and $0.052 below Arkansas ($3.998), completing the top three lowest-priced states. The national average stands at $4.475 per gallon for the week of May 25, 2026, meaning Oklahoma's prices run roughly 11.8% below the national benchmark.
Top 10 States with Lowest Gas Prices (May 2026)
The Southern and Midwestern regions dominate the lowest gas price rankings, reflecting proximity to Gulf Coast refining infrastructure and lower state fuel taxes.
| Rank | State | Average Price (USD/gal) | Below National Average |
|---|---|---|---|
| 1 | Oklahoma | $3.946 | 11.8% |
| 2 | Mississippi | $3.984 | 11.0% |
| 3 | Arkansas | $3.998 | 10.7% |
| 4 | Louisiana | $4.005 | 10.5% |
| 5 | Texas | $4.034 | 9.9% |
| 6 | Georgia | $4.038 | 9.8% |
| 7 | Nebraska | $4.039 | 9.7% |
| 8 | Alabama | $4.067 | 9.1% |
| 9 | Kansas | $4.081 | 8.8% |
| 10 | New Mexico | $4.125 | 7.8% |
Top 5 States with Highest Gas Prices (May 2026)
West Coast states and isolated markets face the highest prices due to stricter fuel specifications, logistics costs, and limited refinery competition.
- California - $6.158/gallon (37.6% above national average)
- Washington - $5.762/gallon (28.8% above national average)
- Hawaii - $5.650/gallon (26.3% above national average)
- Alaska - $5.264/gallon (17.6% above national average)
- Nevada - $5.240/gallon (17.1% above national average)
Price Disparity Analysis: Oklahoma vs. California
The price gap between the cheapest and most expensive states exceeds $2.20 per gallon, representing a 55.8% differential that reflects structural market dynamics. California's premium fuel requirements, carbon pricing mechanisms, and refinery constraints drive its elevated costs, while Oklahoma benefits from Gulf Coast proximity, lower state taxes, and robust domestic production.
LNG Industry Context: How Gasoline Pricing Relates to Liquid LNG Markets
While gasoline prices reflect domestic refining and transportation dynamics, LNG pricing operates through separate global mechanisms tied to natural gas hub indices (Henry Park, TTF, JKM) and long-term contract structures. However, both markets respond to shared inputs: crude oil indexation in some LNG contracts, transportation infrastructure costs, and geopolitical supply chain risks. Understanding regional fuel cost disparities helps energy executives assess transportation economics for LNG feedstock logistics and competing fuel adoption in transport sectors.
Key Takeaways for Energy Executives
- Oklahoma leads with the cheapest gas at $3.946/gallon, 11.8% below national average
- West Coast premiums persist: California exceeds $6.15/gallon, 37.6% above national average
- Gulf Coast states dominate the bottom 10, benefiting from refining infrastructure and lower taxes
- Year-over-year increases of 41% reflect broader energy market tightening since 2025
- Strategic procurement teams should factor regional price differentials into logistics and fleet fueling strategies
Key concerns and solutions for Which State Has The Cheapest Gas The Answer Shocked Us
What factors drive interstate gas price differences?
Four primary factors determine interstate variation: state fuel tax rates (ranging from ~18¢/gal in some states to 50¢+/gal in others), proximity to refining hubs and pipelines, fuel specification requirements (e.g., California's CARB gasoline), and regional supply-demand balance and competition intensity.
How does the national average compare year-over-year?
The US Retail Regular Gas Price is $4.475 for the week of May 25, 2026, up 41.03% from $3.173 one year ago, according to Energy Information Administration data. This represents a -0.33% decline from the prior week's $4.49 level.
Which region consistently offers the cheapest gas?
The Southern US-particularly Oklahoma, Mississippi, Arkansas, Louisiana, and Texas-consistently records the lowest prices due to Gulf Coast refining capacity, lower state taxes, and abundant domestic supply. Today, the lowest gasoline prices in the nation are predominantly found in the Southern and Midwestern regions.
Does gas price vary by day of week?
Yes. A GasBuddy survey found gas is cheapest on Monday and most expensive on Friday and Saturday. Consumers can save by filling up early in the week when demand pressure is lowest.
