Saving 10 cents per gallon at the gas station can feel like a small victory, especially when the price at the pump keeps climbing. Some drivers will happily cross town for the cheaper sign, even if the detour adds 20 minutes to the trip. The trouble starts when the savings look impressive on the receipt but barely register in the household budget.
The math depends on three things: how much fuel the vehicle holds, how far the driver travels, and whether the trip replaces driving that would happen anyway. A bargain station along the usual route can be a genuine win. A special expedition for cheaper gasoline can turn penny-pinching into an expensive hobby, complete with traffic lights.
