Gas Saving Tips for Baton Rouge Drivers

Combine errands into single efficient trips rather than making multiple short trips. Cold engines use significantly more fuel — letting the engine warm up across one longer trip is far more efficient.
Check tire pressure monthly, especially as seasons change — tire pressure drops about 1 PSI for every 10-degree Fahrenheit temperature decrease.
Fill up on Monday or Tuesday mornings — gas prices typically rise Thursday through Sunday as weekend demand increases, then reset lower early in the week.
Use the GasBuddy or Waze app to compare prices within 5 miles of your location before every fill-up. Even a 10-cent difference on 15 gallons saves $1.50 each fill-up.
Join a warehouse club (Costco, Sam's Club, BJ's) — their fuel consistently runs 10-25 cents below local market prices. The membership cost typically pays for itself in fuel savings within the first two months.
