Pay attention to gas station prices, even when you don't need to fill up your own tank. You should begin to notice which gas stations regularly have the cheapest option.
Survey the area you're in before filling up your tank. Gas stations are often concentrated in small areas, such as a truck stop, with their prices listed on large signs. Follow the cheapest prices, and don't let a more expensive gas station reel you in with marketing gimmicks.
