How to save more on gas in Westminster
1. Use warehouse clubs

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.

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.
