The current national average on-highway gasoline price is $3.177, according to the EIA, 3 cents higher than last week’s average. 

Here are this week’s gasoline price highlights from each region of the U.S.:

  • West Coast: Along the West Coast, gas prices rose 4 cents to $4.148. Without including California, gas prices rose 4 cents to $3.877.

According to AAA, the current national gasoline price average is $3.190. This is 1 cent higher than the EIA’s current estimate and 13 cents lower than this time last year.

In a recent press release, AAA said, “The national average for a gallon of regular went up more than 7 cents this past week to $3.21, mainly due to flooding at BP Whiting Refinery in Indiana. The largest refinery in the Midwest shut down operations for several days following a severe thunderstorm. As a result, states in the Great Lakes region saw an increase in gas prices, but they may get some relief soon now that the refinery is back online. Overall, summer gas prices have remained steady and should trend downward as the fall season begins.”
