Finding cheap gas in Baltimore (21218)
Charles Village and Waverly sit in north-central Baltimore, built up in the 1890s as the city's first garden suburb of brick rowhouses and anchored today by the Johns Hopkins Homewood campus and the Baltimore Museum of Art. The district runs roughly up to 33rd Street, with Greenmount Avenue along the eastern edge.
This is dense, rowhouse Baltimore, and dedicated gas stations are genuinely scarce inside the residential blocks where students and longtime residents mostly walk, bike, or take transit. The few stations that exist sit on the busier arterials like Greenmount Avenue and the wider cross streets rather than tucked between the rows.
Maryland carries one of the higher gas taxes in the country, north of 46 cents a gallon, which keeps a floor under prices across the whole city. Within this ZIP your best approach is to fill on the busier through-streets where there is some competition, since the handful of corner stations serving the immediate neighborhood rarely lead on price and you will pay for the convenience near campus.

How to save more on gas in Baltimore
1. Use warehouse clubs
Costco and Sam’s Club typically price 15-25 cents per gallon below nearby stations. Membership pays for itself within a few fill-ups.
2. Fill up early in the week
Stations often raise prices Thursday for weekend demand. Fill up Monday through Wednesday to avoid the lift.
3. Keep tires properly inflated
Properly inflated tires improve fuel economy by up to 3 percent at current prices. Check pressure once a month.
4. Check back tomorrow
Prices can shift 10-20 cents overnight during volatile markets. A quick check before you leave home avoids paying yesterday’s spike.
5. Pay cash at split-pricing stations
Stations with cash and credit split pricing typically save an average of 10 cents per gallon when you pay cash.

About gas prices in Maryland
Maryland is a PADD 1B Central Atlantic state with reformulated gasoline requirements in the Baltimore-DC corridor that add 5 to 15 cents per gallon over the rest of the state. The state gas tax is around 47 cents per gallon, among the highest on the East Coast. Baltimore, Annapolis, and the DC suburbs (Bethesda, Silver Spring, Rockville) all draw supply from harbor terminals at Port of Baltimore plus pipeline imports through Plantation and Colonial systems. Costco, Sam's Club, BJ's Wholesale (popular in the suburbs), Wawa, and Royal Farms lead on value across Baltimore, Annapolis, and Rockville. Western Maryland (Hagerstown, Cumberland) typically tracks Pennsylvania pricing rather than the Baltimore-DC corridor.
