Illinois Fuel Prices Show Modest Declines

Illinois drivers are seeing some relief at the pump as fuel prices dip slightly. The latest figures from AAA show regular unleaded averaging $4.90 per gallon, down from $5 the previous week. Despite the decrease, prices remain significantly higher than a year ago—on May 27, 2025, the average was just $3.41. Diesel users are paying even more, with the statewide average at $5.99 per gallon. Although prices are on a downward trend, motorists continue to face elevated costs compared to last spring’s levels, prompting concern for summer travel budgets across the state.
