Maryland Gas Price FAQs
What is the average gas price in Maryland 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 Baltimore and Western Maryland gas prices differ?
Baltimore benefits from close proximity to marine shipping terminals and high station density, while remote mountain towns in Garrett or Allegany counties face higher transport costs and less local competition.
Does Maryland use special gasoline blends?
Yes, the Baltimore and Washington D.C. metro areas require specific reformulated gasoline (RFG) blends during the summer to reduce smog and meet federal air quality standards.
Is diesel included in Maryland gas price data?
Yes, the tool tracks Maryland diesel prices alongside unleaded options, which is essential for commercial truckers, port logistics fleets, and RV travelers navigating the state’s freight corridors.
Why can Ocean City gas prices be higher in the summer?
Coastal resort towns face massive seasonal tourism spikes. High demand and the logistical cost of delivering fuel down the Route 50 corridor during crowded summer weekends can push retail prices up.
