Finding cheap gas in Washington (15301)
Washington is the county seat of Washington County in southwestern Pennsylvania, sitting at the crossroads of Interstates 70 and 79 with US Route 19 running through. That intersection of two interstates makes it a genuine travel hub, and the stations near those interchanges catch a heavy stream of through-traffic.
Pennsylvania's gas tax is the highest of any state, so the baseline price here runs well above the national average. The competition at the I-70 and I-79 ramps is real, with travel-oriented stations pricing against one another for drivers passing between Pittsburgh and points south and west.
For residents, the stations woven into the city and along Route 19 away from the interstates can sometimes beat the high-volume highway pumps. Washington is also home to a college and sits in the heart of southwestern Pennsylvania's natural-gas country, but at the pump the steep state floor is what matters most, and the gap between the interchange stations and the quieter in-town options is where you can claw a little of it back.

How to save more on gas in Washington
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 Pennsylvania
Pennsylvania has the highest motor-fuel tax in the country at roughly 58 cents per gallon, a legacy of using gas-tax revenue to fund the state highway system rather than relying on tolls. Sheetz, Wawa, and Rutter's are the regional powerhouses for value pricing across Philadelphia, Pittsburgh, and Allentown, while Costco and Sam's Club fuel offer the cheapest absolute prices when membership math works out. Western Pennsylvania (Pittsburgh, Erie) draws fuel from Ohio refineries and tends to price 5 to 10 cents below Philadelphia, which pulls from Northeast pipeline shipments and reformulated gasoline blending.
