IRVING (October 4, 2012)--Regular unleaded gasoline prices in Texas have fallen by an average of 4 cents to $3.54 per gallon, according to the weekly AAA-Texas Weekend Gas Watch survey.

In a statement Thursday, the auto club attributed the drop to global crude oil price declines, the end of the summer driving season, sluggish economic news and a seasonal switch away from more expensive summer gasoline blends.

The statewide average is well below the national average of $3.78, just a penny decrease from last week.

The state's cheapest gasoline was found in Fort Worth, where the average price fell a nickel to $3.47 per gallon.

The most expensive gasoline was in Amarillo, where the average price fell 3 cents to $3.60 per gallon.
