But which states are seeing the biggest spikes - and which the lowest? [iSeeCars answers that question in its new gas costs study](https://www.iseecars.com/fuel-cost-impact-by-state-study). It found that overall annual fuel costs rose by $706 nationally between January and April 2026. State-level increases ranged from $487 to $1,029. Wyoming drivers had the largest statewide increase, with average state-level annual fuel costs increase, climbing by $1,029.  But if you factor in certain vehicles, those costs increased even higher for drivers in some states.   It cites Toyota Sequoia drivers in Tennessee as an example - with their estimated annual fuel costs jumping by $2,190.   Large SUVs dominated the model rankings for fuel-cost increases, led by the Chevrolet Suburban, Nissan Armada, GMC Yukon XL, and Toyota Sequoia. **States With the Biggest Annual Fuel Cost Increases** Here's a look at the top 15 states with the biggest annual fuel cost increases from January through April 2026.  1. Wyoming  - Up $1,029  2. Utah - Up $967  3. Arizona - Up $963  4. Idaho -Up $956  5. Mississippi -  Up $947   6. Oregon - Up $922 7. Louisiana - Up $875 8. Kentucky - Up $872 9.

Washington - Up $846 15. **Texas - Up $837** iSeeCars says these states were not necessarily the places with the highest absolute fuel costs, but their combination of higher annual mileage and rising fuel prices created the largest increase in what drivers can expect to pay over a full year. **States With the Smallest Annual Fuel Cost Increases** The states with the smallest fuel-cost increases were all below the national driving average of 13,323 miles per year. 1. New York - Up $487   2. Hawaii followed - Up $499  3. Massachusetts-  Up $508  4. Vermont - Up $514 5. Pennsylvania -Up $525 About The Study iSeeCars says it analyzed over 2.1 million 3-year-old used cars sold in 2025. Estimated annual fuel costs were calculated based on each vehicle’s average annual odometer reading in each U.S. state and the average cost of fuel in January 2026 vs. April 2026. The dollar difference was used to rank states and models by their increased financial burden.
