HOUSTON (AP) - Retail gasoline prices are sharply higher in Texas this week, compared with last week.
The weekly AAA Texas gas price survey released Friday finds regular self-serve is averaging $2.93 per gallon at pumps in 10 Texas cities. That is nine cents higher than last week.
Nationally, the average price rose seven cents to $3.05 per gallon.
Auto club spokeswoman Rose Rougeau attribute the increase to the spike in crude oil prices, which topped $100 per barrel for the first time this week.
Rougeau says supply worries and speculation are at least partly to blame for the crude oil price spike.
The cheapest gas in Texas is in El Paso, where it's averaging $2.83 per gallon, three cents higher than last week.
The most expensive gas is in Texarkana, where the average rose 12 cents to $3.02 per gallon.
These are average per-gallon prices of regular, self-serve gasoline in Texas and nationally, as well as the change from last week, according to Friday's AAA Texas Weekend Gas Watch:
