The Triple-A Texas Weekend Gas Watch says the statewide average gas price in Texas is $2.72 a gallon for regular unleaded. That price is down three cents from a week ago, and is $1.08 more than a year ago. The national average is $3.04. Crude oil prices are up slightly, gas demand increased over the past week, and price fluctuations are expected over the holiday weekend as more people hit the roads. The average price at the pump in Austin is $2.68.
