As we kick off 2026, the latest data from the Bureau of Transportation Statistics (BTS) brings welcome news for drivers and fleet operators alike. Motor fuel prices closed out December 2025 with notable declines in most categories, offering some relief amid ongoing supply chain and logistics challenges.
National Averages: Gasoline Down, Diesel Mixed
Regular Gasoline: The national average price dropped to $2.89 per gallon in December 2025. This represents a 5.1% decrease from November 2025 and a 4.1% decline year-over-year from December 2024.
Diesel No. 2: Averaged $3.62 per gallon, down 5.4% from the previous month but up 3.5% compared to December 2024.
These trends reflect seasonal demand softening, stable crude oil supplies, and broader economic factors influencing energy markets.
Regional Breakdown for Regular Gasoline
Prices varied significantly across U.S. regions, with the West Coast remaining the outlier on the high end:
Region | December 2025 Price | Year-over-Year Change |
West Coast | $3.87 | +1.7% |
Central Atlantic | $3.01 | -2.7% |
New England | $2.92 | -2.3% |
Lower Atlantic | $2.74 | -5.5% |
Midwest | $2.67 | -7.3% |
Rocky Mountain | $2.58 | -9.0% |
Gulf Coast | $2.47 | -4.9% |
The steepest drops were seen in the Rocky Mountain and Midwest regions, while the West Coast saw a slight increase—likely due to regional refining constraints and higher state taxes.
Implications for Logistics and Supply Chain
At Gain Consulting, we specialize in helping companies navigate fluctuating transportation costs. Lower fuel prices can translate to reduced operating expenses for trucking, parcel, and freight operations—potentially improving margins in a competitive landscape. However, diesel's year-over-year increase serves as a reminder that volatility persists, especially for heavy-duty fleets.
These savings opportunities underscore the value of proactive logistics optimization. Whether through carrier negotiations, route efficiency, or mode shifts, small adjustments can yield significant gains when fuel costs shift.
