How to save more on gas in Ama
1. Use warehouse clubs

2. Fill up early in the week
Stations often raise prices Thursday for weekend demand. Fill up Monday through Wednesday to avoid the lift.
3. Keep tires properly inflated
Properly inflated tires improve fuel economy by up to 3 percent at current prices. Check pressure once a month.
4. Check back tomorrow
Prices can shift 10-20 cents overnight during volatile markets. A quick check before you leave home avoids paying yesterday’s spike.

About gas prices in Louisiana
Louisiana hosts six major refineries along the Mississippi River and Gulf Coast, including ExxonMobil Baton Rouge (one of the largest in the nation), Marathon Garyville, and Phillips 66 Alliance. The state gas tax is around 20 cents per gallon, one of the lowest in the country. New Orleans, Baton Rouge, and Shreveport all post pump prices well below the national average thanks to direct refinery proximity and short supply distances. Costco, Sam's Club, Murphy USA at Walmart, and Brookshire's grocery fuel lead on value across New Orleans, Baton Rouge, and Shreveport. Hurricane season (August through October) creates the only meaningful supply risk, as refinery shutdowns and evacuations can spike prices within days.
