IRVING, Texas (AP) — Retail gasoline prices increased an average of 9 cents across Texas this week.

AAA Texas on Thursday reported the average price at the pump was $2.40 a gallon. The nationwide cost for gasoline increased by 6 cents to settle at $2.52.

Houston had the cheapest gasoline this week at $2.34 a gallon. El Paso gasoline prices were the highest statewide, averaging $2.45.

The auto club says Texas gasoline prices have followed the movements of oil prices for much of the summer and will likely continue to do so in the short term. Some analysts predict prices will not move significantly in either direction barring any unexpected events.
