IRVING, Texas -- Retail gasoline prices across Texas have gone up eight cents this week.
AAA Texas reported on Thursday that the price of a gallon of regular unleaded gas is $3.24. That's up from last week's average of $3.16, but still 18 cents below the national average.
Dallas drivers are paying an average of $3.30, the highest in the state. El Paso has the cheapest average gas at $2.99.
AAA says prices are being driven up by news about a strengthening economy and refinery issues in five states. Prices could rise more as a refinery in New Jersey is set to close at the end of the next month. That will likely require more shipments of Gulf Coast and overseas gas to the Northeast.
