Ohio Motorists are seeing lower gas prices this week and are paying less than the national average. The state average for a gallon of regular gas is $3.56 in Monday’s survey from auto club AAA. That’s 9 cents lower than last week. The Ohio price is 11 cents below the national average of $3.56, which is 6 cents higher that the national average a week ago. Analysts expect further increases in pump prices this summer as greater demand, unrest in Egypt and production disruptions in the U.S. and other countries push up the price of crude oil and gasoline. The cheapest average gas price in Ohio Monday is in Toledo at $3.47. GasBuddy.com is reporting gasoline selling for $3.36 cents a gallon at the Marathon at 515 State Street.
