The average price of a gallon of regular unleaded remained steady as a national average, while the price in California jumped 16 cents for the week ending Oct. 7, according to AAA.
While the national average remained at $2.65, more than half of the stations are selling regular unleaded for $2.50 or less, while 77% are selling it for $2.75 or less. Gasoline is 9 cents more expensive than a month ago and 26 cents cheaper than a year ago.
The increase in California to $4.18 per gallon is a result of tighter gasoline stocks on the West Coast, said Jeanette Casselano, AAA spokesperson.
"All regions are seeing planned and unplanned refinery maintenance, but it is only the West Coast that is really seeing gasoline stocks tighten and gas prices increase," Casselano said. "On the whole, we are seeing gasoline demand mostly push lower amid stable, but healthy gasoline stock levels which are ultimately keeping prices cheaper for most motorists."
States with the largest weekly changes after California include Nevada (up 14 cents), Indiana (down 8 cents), Delaware (down 8 cents), Michigan (up 6 cents), Oregon (up 6 cents), Washington (up 5 cents), Georgia (down 5 cents), Maryland (down 4 cents), and Texas (down 4 cents).
States with the least expensive gasoline include Louisiana ($2.27), South Carolina ($2.28), Mississippi ($2.28), Texas ($2.31), Alabama ($2.31), Arkansas ($2.31), Missouri ($2.32), Virginia ($2.32), Oklahoma ($2.33), and Tennessee ($2.34).
Meanwhile, the price of a gallon of diesel fell 1.9 cents to $3.047, which is 33.8 cents lower than a year ago, according to the U.S. Energy Information Administration.
