How Much Is E85 Per Gallon? The Current Price and LNG Comparison
As of the October 1-15, 2025 reporting period, the national average price for E85 fuel is $2.63 per gallon, according to the U.S. Department of Energy's Alternative Fuels Data Center. By comparison, LNG (liquefied natural gas) for transportation sells at $4.86 per gasoline gallon equivalent (GGE) in the same period, making E85 approximately 46% cheaper on a per-gallon basis. However, because E85 contains 73%-83% of the energy in a gallon of gasoline, the BTU-adjusted cost narrows the practical savings for fleet operators evaluating total operating expenses.
Current E85 Pricing Data and Historical Context
The E85 retail price has fluctuated significantly over recent years, reflecting ethanol production volumes, corn commodity prices, and gasoline spot markets. On October 1, 2024, the national average stood at $3.56 per gasoline gallon equivalent, down from $4.316 per gallon recorded on June 10, 2022 during peak gasoline prices. The lowest E85 price in the historical record occurred in April 2020 at $2.28 per GGE amid pandemic-driven demand collapse.
E85 vs. LNG: Side-by-Side Fuel Property Comparison
Understanding the energy density gap is critical for procurement teams comparing E85 and LNG. While E85 appears cheaper per gallon, LNG delivers more energy per unit volume, which affects tank sizing, refueling frequency, and total cost of ownership for heavy-duty fleets.
| Fuel Property | E85 (Ethanol) | LNG (Liquefied Natural Gas) |
|---|---|---|
| National Average Price | $2.63/gallon | $4.86/GGE |
| Energy Content vs. Gasoline | 73%-83% of 1 GGE | 100% by definition (1 GGE) |
| Price per Million BTU | ~$12.40/MMBtu (estimated) | ~$18.50/MMBtu (estimated) |
| Primary Feedstock | Corn ethanol + gasoline | Natural gas + biogas |
| Fleet Vehicle Compatibility | Flex-fuel vehicles only | CNG/LNG heavy-duty trucks |
Key Factors Driving E85 Price Volatility
Three primary variables determine E85 pricing at the pump, and executives monitoring ethanol market dynamics should track these indicators for procurement forecasting:
- Corn commodity prices: Ethanol represents ~85% of E85 by volume, and corn accounts for 40%-50% of ethanol production costs.
- Gasoline spot prices: E85's 15% gasoline component ties its floor price to RBOB gasoline futures.
- RFS blending mandates: The Renewable Fuel Standard creates baseline demand that supports ethanol pricing during low-corn-price cycles.
Why LNG Commands a Premium Despite Lower Feedstock Costs
LNG's $4.86/GGE price reflects significant liquefaction infrastructure costs that ethanol blending does not incur. Producing LNG requires cooling natural gas to -260°F, a process consuming 10%-15% of the gas's energy content and requiring capital-intensive cryogenic tanks at refueling stations. By contrast, E85 leverages existing gasoline distribution infrastructure with minimal modification, keeping downstream costs lower despite ethanol's higher per-BTU production expense.
- Step 1: Calculate cost-per-mile using fuel economy data (E85 typically achieves 20%-25% lower MPG than gasoline).
- Step 2: Adjust for energy content: divide nominal price by energy fraction (e.g., $2.63 ÷ 0.77 = $3.42/GGE equivalent).
- Step 3: Compare to LNG's $4.86/GGE and factor in vehicle-specific maintenance savings (LNG engines often have longer oil-change intervals).
Regional E85 Price Variation and Availability
E85 pricing exhibits significant regional dispersion due to ethanol transport costs and state-level incentives. Minnesota, Iowa, and Illinois-where corn production is concentrated-typically offer E85 $0.15-$0.30 below the national average, while West Coast stations charge premiums due to captive gasoline markets and lower ethanol blending volumes. As of April 2025, the Clean Cities Alternative Fuel Price Report showed E85 ranging from $2.57/gallon in the Midwest to $2.82/gallon nationally.
"E85 often gives drivers more bang for the buck than regular gasoline when adjusted for the price per mile, but fleet CFOs must account for the 20% fuel economy penalty in long-haul operations."

Strategic Implications for LNG Industry Stakeholders
For executives in the LNG value chain, E85's $2.63/gallon price point represents a competitive benchmark for light-duty and medium-duty fleet conversion decisions. While LNG dominates heavy-duty long-haul applications due to its superior range and energy density, E85 remains the default alternative for flex-fuel pickup trucks and municipal fleets operating under tight capital constraints. The $2.23/gallon nominal spread ($4.86 - $2.63) narrows to approximately $0.80-$1.20/GGE after energy adjustment, keeping LNG viable for operators prioritizing total cost of ownership over upfront fuel price.
Expert answers to How Much Is E85 Per Gallon Vs Lng The Fuel Comparison Nobody Made queries
What is the current E85 price per gallon?
The current national average E85 price is $2.63 per gallon as of October 1-15, 2025, representing a 26% decline from the October 2024 level of $3.56 per GGE.
How does E85 price compare to regular gasoline?
E85 typically sells for $0.20-$0.30 more per gallon than regular gasoline in normal market conditions, though the spread widened significantly in 2022 when E85 was $0.67-$2.00 cheaper depending on regional gasoline prices.
Is E85 cheaper than LNG for fleet operations?
Yes, E85 at $2.63/gallon is substantially cheaper than LNG at $4.86/GGE on a nominal basis, but fleet economists must adjust for E85's 17%-27% lower energy content per gallon when calculating cost-per-mile.
Where can I find real-time E85 prices?
The U.S. Department Energy's Alternative Fuels Data Center publishes biweekly national averages every October 1-15 and April 1-15, while AAA provides daily gasoline and E85 tracking on its fuel price dashboard.
Does E85 price include federal ethanol taxes?
No, E85 at the pump reflects the blended fuel price without separate line-item ethanol taxes; however, ethanol producers claim the Small Refinery Exemption and Renewable Identification Number (RIN) credits that indirectly affect rack pricing.
Will E85 prices rise in 2026?
Analysts project modest E85 price increases in 2026 if corn harvests remain below trend and RFS mandates expand, but current futures suggest a range of $2.50-$3.00/gallon through mid-2026.
