Gas Pump Habits That Could Be Draining Your Wallet

Gas prices may fluctuate, but one thing that remains constant is everyone wants to save money at the pump. While you can’t control fuel prices, you can control your habits when filling up. Unfortunately, some common gas station practices could be quietly draining your wallet. Here are four habits you should avoid to make the most of every gallon.

1. Topping Off Your Tank

Topping off your tank after the pump automatically shuts off might seem like a good idea, but it’s not. This habit can cause fuel to overflow or get sucked back into the pump’s vapor recovery system, meaning you’re paying for gas you’re not even keeping and potentially damaging your vehicle. Trust the pump to know when your tank is full and resist the urge to add those extra cents.

2. Not Using Rewards or Discount Programs

Many gas stations and grocery stores offer rewards programs or fuel discounts that can help you save a few cents per gallon. Skipping out on these programs means you’re leaving money on the table. Sign up for loyalty cards, use apps that track gas prices, or take advantage of grocery store promotions that offer fuel discounts. These small savings can add up significantly over time.

3. Ignoring Tire Pressure

While this habit doesn’t happen directly at the pump, it’s one of the biggest contributors to wasted fuel. Underinflated tires increase rolling resistance, which forces your engine to work harder and burn more gas. Before heading to the station, check your tire pressure and inflate them to the manufacturer’s recommended levels. A quick check can save you money on both gas and tire wear.

4. Not Checking for Price Differences Between Pump Grades

Some stations display the price for regular gas prominently, but the price jump to mid-grade or premium might not be obvious until you’re already pumping. Always double-check the price of the grade you’re selecting before you lift the nozzle. Accidentally choosing the wrong button could mean paying significantly more than you intended.

5. Leaving the Engine Running While You Pump

Leaving your car running while fueling up might seem harmless, but it’s unnecessary and can even be unsafe. More importantly for your wallet, idling wastes fuel—especially if you’re waiting for a line to move or letting the pump run slowly. Shutting off the engine not only saves gas but avoids potential wear and tear.

6. Not Fully Inserting the Nozzle

If the pump nozzle isn’t properly inserted into your tank, it can trigger the auto shut-off too early or cause fuel to spill. That means you might stop short of a full fill or lose money to drips and vapor loss. Always make sure the nozzle clicks securely into place before squeezing the handle.
