Fill up before holidays.
As you probably know, holidays are the worst times to fill up with gas. Because more people are on the road, gas stations will all typically dramatically raise their prices. This doesn’t mean you shouldn’t drive close to holidays, however. Just be sure you fill up your tank before the holiday break. Prior to Labor Day, Thursdays through Mondays can mean the highest prices. After Labor Day, Wednesdays and Thursdays can signal increases. Watch for station promotions throughout the year, and jump on them when you can.
