AAA Texas Weekend Gas Watch says the statewide average gas price in Texas is $3.05 a gallon for regular unleaded. That price is up three-cents from a week ago, and is $1.20 more than a year ago. The national average is $3.40. A drop in demand has helped slow price increases, but crude prices above $80 a barrel are keeping pump prices high. The average price at the pump in San Antonio is $2.94.
