31 a gallon, based on AAA’s list of average state prices

California had the most expensive price for gasoline on Oct. 12 at $6. 31 a gallon, based on AAA’s list of average state prices. You can often find prices lower than the state average at convenience store gas stations, as I paid $6. 09 a gallon at a nearby AM PM minimart in Northern California on Oct. 11. Consumers in other states, such as those in the South, can find gasoline at convenience store gas stations, such as RaceTrac, for about $2 to $2. 50 less than California stations, with state gas averages of about $3. 80 in Georgia, $3. 82 in Texas, and $4. 07 in Florida.
