While the national average price for a gallon of gas fell below $3, the average price for a gallon of gas in San Luis Obispo County fell eight cents last week to $4.67 a gallon, according to figures from AAA.

In California, the average price for a gallon of gas dropped nine cents to $4.47. Nationally, gas prices fell five cents to $2.9o a gallon.

“The last time the national average reached an even $3.00 or below was in May of 2021,” according to AAA. “Crude oil prices remain on the lower side around $60 a barrel. Sluggish gas demand and cheaper-to-produce winter blend gasoline are also contributing to the drop at the pump.”

SLO County currently has the ninth highest price for gas in the state. Listing the highest average price, Mono County’s price for a gallon of regular gasoline this week is $5.67. Amador County boasts the lowest average cost at $4.02 a gallon.
