Gasoline prices are once again on the rise.
Regular gasoline is selling for as high as $3.73 a gallon in Erie today, with most retailers charging $3.65 to $3.69 a gallon.
AAA reported Tuesday that prices in western Pennsylvania had risen an average of 6 cents a gallon to $3.72, up substantially from the $3.56 most stations were charging on this date in 2013.
A AAA analyst points to a pair of reasons for the recent high prices.
One of those factors has been the continued unrest between Russia and Ukraine.
Closer to home, AAA notes that refineries are required to began producing summer-blend gasoline by May 1, and often shut down for scheduled maintenance this time of year.
“This decrease in supply can cause prices in certain areas to rise,” according to the car club.
