Wyoming Average Gas Prices: Current Benchmarks and LNG Context
As of May 30, 2026, the wyoming average gas prices for regular unleaded gasoline stand at $4.454 per gallon, according to AAA fuel price data. This represents a 2.0-cent-per-gallon increase from the previous week and positions Wyoming's regular gasoline at approximately 10 cents above the AAA national average of $4.356 per gallon. Diesel fuel in Wyoming averages $5.394 per gallon, while mid-grade and premium grades average $4.720 and $5.026 per gallon respectively.
Current Wyoming Gas Price Breakdown by Grade
| Grade | Current Avg. (May 30, 2026) | Yesterday Avg. | Week Ago Avg. | Month Ago Avg. | Year Ago Avg. |
|---|---|---|---|---|---|
| Regular | $4.454 | $4.479 | $4.534 | $4.070 | $3.149 |
| Mid-Grade | $4.720 | $4.761 | $4.822 | $4.376 | $3.433 |
| Premium | $5.026 | $5.067 | $5.122 | $4.652 | $3.714 |
| Diesel | $5.394 | $5.419 | $5.499 | $5.123 | $3.435 |
The year-over-year comparison reveals Wyoming gasoline prices have risen approximately 41.4% for regular grade since May 2025, when prices averaged $3.149 per gallon. Diesel fuel shows an even steeper increase of 57.0% year-over-year, reflecting broader tightness in heavy-fuel supply chains.
Regional Variation Within Wyoming
Gas pricing varies significantly across Wyoming's major metropolitan areas, with Casper and Cheyenne showing distinct local market dynamics. Casper's current regular gasoline average stands at $4.268 per gallon, approximately 19 cents below the state average. Cheyenne reports a current average of $4.317 per gallon for regular gasoline, still 14 cents below the statewide benchmark.
- Casper regular: $4.268/gallon (19 cents below state average)
- Cheyenne regular: $4.317/gallon (14 cents below state average)
- Cheapest station statewide: $3.17/gallon (GasBuddy survey)
- Most expensive station statewide: $4.29/gallon (GasBuddy survey)
- Price spread across Wyoming: $1.12/gallon
LNG Cost Benchmarks: The Industrial Alternative
For industrial and commercial fleet operators evaluating fuel alternatives, LNG pricing benchmarks provide a critical comparison point against conventional gasoline and diesel. As of April 1, 2026, LNG bunker vessel prices in the ARA (Amsterdam-Rotterdam-Antwerp) region range from $860-870 per metric ton for bulk contracts of 1,000 MT and 250 MT respectively. When converted using the high heating value factor of 15.28 MWh/MT, these prices translate to approximately $56.50-57.10 per MWh.
- LNG bunker vessel ARA region (250 MT): $870/MT
- LNG bunker vessel ARA region (1,000 MT): $860/MT
- LNG bunker vessel Baltics (250 MT): $900/MT
- LNG bunker vessel Baltics (1,000 MT): $885/MT
On an energy-equivalent basis, LNG remains competitive for heavy-duty transportation applications where diesel substitution economics favor lower per-MWh fuel costs despite higher infrastructure investment requirements. The Baltics region commands a premium of approximately $30-35 per MT over ARA pricing, reflecting regional supply constraints and transportation logistics.
Historical Price Context and Volatility Patterns
Wyoming gasoline prices have experienced significant volatility throughout 2026, with the monthly price trajectory showing a clear upward trend from April's $3.980 average to May's $4.454 average. The month-to-month increase of 11.9% represents one of the steepest single-month jumps observed in Wyoming's recent fuel price history.
GasBuddy's survey of 494 Wyoming stations indicates average prices rose 2.0 cents per gallon in the week ending May 30, 2026, while the national average fell 1.4 cents per gallon to $3.56/gallon during the same period. This divergence suggests Wyoming-specific supply dynamics, potentially related to regional refinery throughput, pipeline constraints, or seasonal demand patterns unique to the Mountain West.
Strategic Implications for LNG Industry Stakeholders
For executives and procurement teams monitoring the liquefied natural gas ecosystem, Wyoming's gasoline price trajectory provides contextual market intelligence regarding regional fuel demand patterns and substitution economics. The sustained premium of Wyoming gasoline over national averages, combined with diesel's steeper 57.0% year-over-year increase, creates a compelling economic case for LNG adoption in commercial fleet operations where total cost of ownership calculations favor lower per-energy-unit fuel costs.
Information on global LNG cargo tracking and independently-sourced spot price assessments from ICIS covers 700 LNG vessels globally, providing the analytical infrastructure necessary for evidence-based procurement decisions in volatile fuel markets. Decision-makers should integrate these gasoline price benchmarks with LNG contract structures to optimize long-term fuel procurement strategies across the complete LNG value chain.
