The national average rose slightly over the last week due to continued refinery challenges in the western U.S. that have pulled gas prices up considerably in some states, while one in five states have seen average gasoline prices decline in the last week, according to Patrick De Haan.

The head of petroleum analysis at GasBuddy said motorists should see prices eventually cooling back off, but if refinery issues continue to develop or linger, especially now with maintenance season and less availably capacity online, the expected decline could be offset.

“In addition, with oil prices now above $91 for the first time in nearly a year, there remains some offset from the rising price of oil thanks to Saudi Arabia and Russia’s war on low oil prices, now in its third month,” De Haan said.

Average gasoline prices in Texas have risen 7.8 cents per gallon in the last week, averaging $3.41/g today, according to GasBuddy’s survey of 13,114 stations in Texas.
