If you've traveled along the interstate in our tri-state area recently, you may have noticed the shocking difference in gas prices between Pennsylvania, New York, and Ohio.

According to AAA, the average price of gas in Ashtabula County is $3.15 per gallon, compared to Chautauqua County's average price of $3.31 per gallon, and Erie County's average of $3.72 per gallon. 

The price difference is leading to some drivers to search for cheaper gas across state lines.

"At the price right now it's $0.60 less than it is in Erie, so it's quite the savings," said Eileen Bowen, who's traveling from McKean, PA to Cleveland, and filling up at the Shell gas station on Ohio Route 7. 

"From McKean to here it's less than 1/2 an hour," continued Bowman. "So I guess you have to figure out is it worth the mileage and how much you're going to save, and if you have the time to do it."

But gas prices aren't just cheaper in Ohio. In New York State, at the Seneca Native Reservation, prices can be found for as low as $2.93 a gallon.

Dave Wharton, a Western New York native traveling to Indiana, says the reservation is usually where he fills up, as it's cheaper than other gas stations near him.

"The [reservation] is usually anywhere from 20 to 50 cents cheaper, depending on where you shop around. Here [in Ohio] it's about a dime cheaper, so for a dime I don't stop."

So with Pennsylvania's gas prices so high, would it be better for to simply cross over into Ohio or New York for cheap fuel?

"If you do the math you're really only saving a total of $5 to $6 to fill your tank," said Tiffany Stanley, Public & Community Relations Manager for AAA East Central.

"So we would suggest that you do not take that trip, especially because if you're down to about 1/4 of a gallon of gas, you risk possibly getting stranded on the side of the road, or running out of gas. So we would not suggest that you take that trip."

Stanley says those who live close to state borders may find it more economical to cross the border for cheaper gas. 

Stanley also adds that consumers should brace for seasonal gas price increases as summer grows closer.
