Gas Siphoning & Gas Theft Are Rising: How to Protect Your Vehicle
Gas prices are climbing again. Unfortunately, the value of what’s sitting inside your vehicle’s fuel tank is climbing with them.
According to the U.S. Energy Information Administration, the national average price for regular gasoline reached $4.07 per gallon for the week ending August 31, 2026, nearly $0.90 more than a year earlier. Diesel prices have risen even more sharply. The national average reached $5.60 per gallon, while California drivers were paying an average of $7.22
While there isn’t a single national database that directly correlates rising gas prices with gas siphoning, periods of high fuel prices have repeatedly been accompanied by reports from police departments, insurers and news organizations of increased fuel theft.
And today’s thieves aren’t necessarily using a siphon.
Gas Siphoning Isn’t the Only Problem Anymore
When most people picture someone stealing gasoline, they probably imagine a hose being inserted into a gas tank.
But modern vehicles have made traditional siphoning more difficult. As a result, thieves have increasingly turned to a far more destructive method: drilling directly into the fuel tank.

The stolen gasoline might be worth $50 or $100. The damage left behind can cost significantly more. In April 2026, The Washington Post reported on the spread of “drill-and-drain” gas theft as fuel prices increased, with some resulting repair costs approaching $3,000.
That means fuel theft isn’t necessarily just about losing what’s inside the tank anymore. It’s about protecting the vehicle itself.
Fuel Theft Is Making Headlines Again
Reports from around the country show that fuel theft is becoming a renewed concern for both individual vehicle owners and businesses with fleets.

“As fuel prices rise, a new technique of gas theft is spreading”
The Washington Post documented thieves bypassing anti-siphoning protections by drilling directly into vehicle fuel tanks. The report noted that some repairs resulting from the damage can approach $3,000.
JUNE 2026 | Kauaʻi Police Department
Police warn public about increase in vehicle fuel thefts
The Kauaʻi Police Department issued an official warning after an increase in reported fuel thefts. Police said suspects were cutting fuel lines and drilling holes into gas tanks, with incidents occurring in residential neighborhoods, business parking lots, hiking trail entrances and other locations.
Local reporting indicated approximately 20 gasoline theft reports over a three-month period.
JUNE 2026 | Tacoma, Washington
32 fuel-theft reports — many involving commercial and fleet parking
Tacoma Police identified 32 reports of fuel theft in 2026, according to KIRO 7.
Police said many incidents occurred in large parking areas where multiple vehicles were parked together, including commercial lots and fleet parking sites. Tacoma Police specifically encouraged vehicle owners and businesses to use lighting and surveillance systems and report suspicious activity.
How to Prevent Gas Siphoning and Fuel Theft
No single security measure can completely prevent fuel theft. Instead, the goal is to make your vehicle — or your entire parking area — a more difficult and higher-risk target.
1. Park in a Garage or Secured Area
Whenever possible, park vehicles inside a garage, behind a locked gate or within another controlled-access area.
This becomes particularly important for businesses with fleets, where multiple vehicles — and potentially hundreds of gallons of fuel — may be accessible from a single parking lot.
2. Park in Well-Lit, Visible Areas
Choose parking areas with good lighting and visibility whenever possible. If your property or parking area is poorly lit, consider adding motion-activated lighting around vehicles and other vulnerable areas.
The Kauaʻi Police Department specifically recommends parking in well-lit areas and using motion-activated lights as precautions against fuel theft. Thieves benefit from darkness, privacy and time. Better lighting and visibility can make a vehicle or parking lot a less attractive target.
3. Consider a Locking Gas Cap
If your vehicle supports one, a locking fuel cap can provide another barrier against traditional siphoning.
However, it’s important to recognize its limitations. A locking gas cap won’t prevent a thief from accessing a fuel line or drilling directly into the tank. Think of it as one layer of security rather than a complete solution.
4. Be Strategic About How You Park
When possible, position vehicles so that accessing the fuel tank is more difficult. For example, parking near a wall, fence or another vehicle may restrict access to certain parts of the vehicle.
Businesses should also pay attention to where fleet vehicles are stored overnight. Tacoma’s recent experience is particularly relevant: police said many of its 2026 fuel-theft cases occurred around commercial lots and fleet parking areas.
5. Use Video Surveillance
Security cameras can provide visibility into parking areas and valuable evidence if a theft occurs.
Both Kauaʻi Police and Tacoma Police have recommended surveillance as a precaution against fuel theft.
But there’s an important distinction between recording a theft and responding to one.
What If Someone Could Intervene While the Theft Was Happening?
That’s exactly what happened during a recent Deep Sentinel intervention.
A suspicious individual approached a parked vehicle and attempted to siphon fuel. Instead of the vehicle owner discovering what happened the following morning, Deep Sentinel’s security system detected the activity and alerted a Live Surveillance Guard.
The Guard assessed the situation and intervened while the incident was still taking place.
The individual left the property.
That’s the difference between having footage of a crime and having an opportunity to prevent it.
Fuel Theft Can Be an Even Bigger Problem for Businesses
For an individual, a stolen tank of gasoline is frustrating.
For businesses operating fleets of trucks, vans, construction vehicles or other equipment, the consequences can extend well beyond the cost of the fuel. Consider a business with 20 vehicles parked together overnight. A thief isn’t necessarily gaining access to one gas tank — they’re gaining access to an entire fleet.
And if thieves drill into tanks or cut fuel lines, businesses can also face:
- Vehicle repair costs
- Towing expenses
- Insurance claims
- Employee downtime
- Missed appointments or deliveries
- Rental or replacement vehicle costs
Recent incidents reinforce that risk. Tacoma Police specifically noted that commercial lots and fleet parking areas were among the locations being targeted. For contractors, utilities, property managers and other businesses operating vehicle fleets, protecting fuel should therefore be considered part of protecting the property itself.
Don’t Just Record the Crime. Help Prevent It.
Locks, lighting, secured parking and cameras can all make fuel theft more difficult. But ultimately, security comes down to how quickly suspicious activity is identified.
A traditional security camera may provide footage showing exactly how someone stole your fuel.
Proactive video monitoring provides an opportunity to do something while they’re still there.
