COLUMBUS, Ohio -- After weeks of increases, Ohio gas prices have flattened out.
The cost for a gallon of regular gas in Ohio was averaging $3.58 in Monday's survey from auto club AAA, the Oil Price Information Service and WEX Inc. That's about a penny lower than last Monday.
Monday's price is 35 cents higher than a month ago, but is 2 cents lower than last year at this time.
The national average Monday was about $3.50 per gallon, which is up 4 cents from last week, and 23 cents higher than a month ago.
Analysts say prices are up because of seasonal maintenance at refineries, and crude oil prices rising as Russia's advance into Ukraine raised fears of economic sanctions against one of the world's major energy producers.
