Ohio’s average gas price is lowest in U.S. Posted on January 30, 2017 0 COLUMBUS (AP) — Ohio is beginning this week with the lowest average gas prices in the country. The state average for a gallon of regular gas was $2.02 in today’s survey from auto club AAA, the Oil Price Information Service and WEX Inc. Ohio edged out neighboring Indiana by a penny to claim the lowest average. Prices in Ohio have dropped from an average of $2.35 a month ago and $2.13 last week. But they haven’t fallen enough to match the state average at this time last year, which was around $1.66. The national average was $2.27 today, down a few pennies from a month earlier but higher than the average of $1.80 a year ago. AAA says increases in U.S. oil production contributed to gas price decreases in recent weeks.
