How a Metal Screw Can Cost You Hundreds at the Gas Pump
By Greg Collier
Most people know to watch for credit card skimmers at gas stations. They know to cover their PINs and keep an eye on suspicious devices attached to payment terminals.
But what if a thief didn’t need to steal your card information at all?
What if all they needed was a small screw and a few seconds of your time?
Police in the Chicago suburb of Northlake are warning drivers about a surprisingly simple scam that allows criminals to steal gasoline using someone else’s active transaction. While the reports are currently coming from the Chicago area, there is little reason to believe the scam will stay there for long.
Like many successful scams, it is inexpensive, easy to perform, and depends on victims following their normal routines.
What’s Going On?
According to police, thieves are placing small screws inside the nozzle cradle of gas pumps.
The cradle is the section where the nozzle rests when a driver finishes pumping gas. Under normal circumstances, returning the nozzle signals the pump that the transaction has ended.
However, when a screw is inserted in the right spot, the nozzle cannot fully engage the mechanism designed to end the transaction.
To the driver, everything appears normal.
They finish pumping.
They return the nozzle.
They get into their vehicle.
They drive away.
The problem is that the pump may still think the transaction is active.
Once the victim leaves, a thief can simply pull up to the same pump and begin pumping fuel. The gas is then charged to the previous customer’s payment method.
Why It Works
This scam exploits something most drivers never think about.
People assume that putting the nozzle back automatically ends the transaction.
In most cases, that’s true.
Drivers are often focused on getting back on the road, checking directions, answering a phone call, or dealing with passengers. Few people stand at the pump long enough to confirm that the transaction has completely reset.
That brief moment of inattention is precisely what criminals are counting on.
Unlike skimming devices that require collecting card data and later making fraudulent purchases, this scam creates an immediate payoff. The thief gets gasoline right away while the victim drives off unaware that the meter may still be running.
Why Criminals May Like This Scam
From a criminal’s perspective, this method has several advantages.
- It is low-tech.
- It requires minimal equipment.
- It does not involve hacking.
- It does not require stealing card information.
- It leaves victims confused about how the fraud occurred.
Perhaps most importantly, many victims may not immediately notice the theft. They may assume the higher charge was caused by fluctuating fuel prices, a billing error, or simply not paying close attention to the final amount.
That delay gives thieves additional time before anyone realizes what happened.
Red Flags
Drivers should watch for:
- Screws or other objects lodged in the nozzle cradle.
- A nozzle that doesn’t seem to seat properly.
- A pump that does not reset after fueling.
- Missing prompts asking whether you want a receipt.
- Screens that continue displaying the previous transaction.
- Strangers attempting to “help” with the pump.
If something feels unusual, trust your instincts and notify station employees.
Quick Tip: Do not leave until the pump screen resets, asks whether you want a receipt, or returns to zero.
What You Can Do
Police recommend taking a few precautions whenever you fuel up:
Inspect the Pump:
Look at the nozzle cradle before pumping. Check for screws, obstructions, or anything that appears out of place.
Listen for the Click:
Make sure the nozzle fully seats when you return it to the pump.
Wait for the Reset:
Do not leave immediately after hanging up the nozzle. Watch the screen until the transaction officially ends.
Print a Receipt:
A receipt creates a record of your transaction and helps you identify any discrepancies later.
Decline Unsolicited Help:
Do not allow strangers to handle the pump or return the nozzle for you.
Report Suspicious Pumps:
If you find a tampered pump, notify station personnel immediately.
If You Think You’ve Been Targeted
If you suspect someone used your payment method to purchase fuel:
- Contact the gas station immediately.
- Review your receipt and compare it to the charge on your account.
- Notify your credit card company or bank.
- Monitor your account for unauthorized activity.
- Report the incident to local law enforcement.
The sooner you report suspicious charges, the easier it may be to dispute them.
Final Thoughts
Some of the most effective scams are not sophisticated at all.
They do not require malware, stolen passwords, or advanced technology. They simply take advantage of assumptions and routine behavior.
That is what makes this gas pump scam particularly concerning.
Today, the warnings are coming from the Chicago area. Tomorrow, the same trick could appear at gas stations hundreds or even thousands of miles away. Criminals have always been quick to copy schemes that are cheap, simple, and profitable.
The next time you fill up your tank, it may be worth spending a few extra seconds watching the pump reset.
Because if the transaction never really ended, someone else could be driving away with fuel that you paid for.
