Texas gas prices average $1.57 per gallon

The price of gas keeps tumbling across Texas, settling at $1.57 per gallon this week.

AAA Texas on Thursday reported the average retail price per gallon slipped 12 cents compared to last week.

The nationwide average for gasoline also declined 12 cents to $1.66.

AAA Texas says gasoline prices this week are about $1.30 less than one year ago.

Amarillo has the least expensive gasoline, at $1.42 per gallon, down 15 cents from last week. The association's survey found El Paso with the most expensive gas, averaging $1.69, which is down 11 cents from last week.

Association spokeswoman Sarah Schimmer says demand has fallen for oil and gasoline, in part because increased unemployment has led to less commercial activity.
