It marked the second largest increase in any state and the highest prices in Oklahoma since December.
On the week, 28 states saw gas price averages increase by at least a nickel, pushing the national gas price average up six cents to $2.33.
Today’s gas price average is nine-cents more expensive than last month, but 19-cents cheaper than a year ago.
It is the largest one-week increase seen at the national level this year.
