AAA Texas says retail gasoline prices have held steady this week and remain at an average $3.16 per gallon. The association survey also found nationwide prices at the pump were also unchanged Thursday at $3.41 per gallon. El Paso has the highest average gasoline prices statewide at $3.24 per gallon. Beaumont and the Dallas-Fort Worth area have the least expensive gasoline at $3.10. AAA says gasoline prices have been declining amid the transition to winter-blend fuel, which is less expensive to produce, plus cheaper crude oil prices and lower demand.
