Delaware Gas Price FAQs
What is the average gas price in Delaware today?
The current daily averages for regular, mid-grade, premium, and diesel are displayed in the dynamic tool at the top of this page.
Why do Wilmington and Dover gas prices differ?
Wilmington is heavily influenced by the Philadelphia metro market and I-95 commuter demand, while Dover relies more on regional Delmarva supply chains and US-13 traffic patterns.
Why can beach towns cost more at the pump in summer?
Stations in coastal areas like Rehoboth Beach face massive seasonal tourism spikes. Higher demand and the logistical cost of delivering fuel down the peninsula during crowded summer weekends can push retail prices up.
Is diesel included in Delaware gas price data?
Yes, the tool tracks Delaware diesel prices alongside unleaded options, which is essential for commercial truckers, agricultural transport, and RV travelers navigating the state’s freight corridors.
Are Delaware gas prices higher or lower than nearby states?
Delaware prices often sit between Pennsylvania and Maryland. Because Delaware does not have a state sales tax, some border shoppers assume fuel is always cheaper, but daily pump prices depend heavily on wholesale supply costs and local station competition.
