Delaware gas prices

See Delaware fuel infrastructure See your local terminals in Delaware

Delaware has relatively moderate gas prices for the mid-Atlantic region. The state's gas taxes are lower than its neighbors, especially compared to Pennsylvania and New Jersey. That tax advantage makes Delaware a popular fill-up stop for drivers traveling the I-95 corridor.

The state is small and close to the Philadelphia-area refinery complex, which gives it good access to fuel supply. Delaware doesn't have its own refineries, but proximity to the mid-Atlantic refining hub keeps transportation costs low. Prices across the state are fairly uniform since it's only about 100 miles from top to bottom.
