I've Misfueled - What Do I Do?
If you've accidentally put the wrong fuel in your vehicle, don't panic. Follow these steps to protect your vehicle and ensure proper remediation.
⚠️ IMPORTANT: Know the Correct Extraction Method
✗ NOT CERTIFIED
Filler Neck Extraction
Attempting to extract fuel through the filler cap opening. This bypasses anti-siphon safety devices and is NOT manufacturer-approved.
✓ USIFDA CERTIFIED
OEM-Prescribed Methods Only
Fuel pump access panel removal OR full tank removal - following your vehicle manufacturer's service procedures.
Ask your technician: "Will you be using fuel pump access or tank removal?" If they say filler neck extraction, find an USIFDA certified operator.
🚨 IMMEDIATE ACTION REQUIRED
IF YOU HAVE MISFUELED YOUR VEHICLE:
- DO NOT START THE ENGINE - This is critical!
- DO NOT TURN THE IGNITION KEY
- DO NOT ATTEMPT TO DRIVE
- DO NOT attempt to drain fuel yourself
- Contact ONLY operators displaying the USIFDA Mark
Starting the engine will circulate contaminated fuel throughout your vehicle's system, causing extensive damage and significantly higher repair costs.
✅ How to Find a Certified Operator
Look for operators displaying the USIFDA Mark. This mark guarantees:
- Documented DOT/PHMSA hazmat compliance where transport is required
- Proper insurance coverage ($2M+ professional liability (E&O) and commercial general liability)
- Certified fixed repair facilities (USIFDA has not yet certified any mobile operators)
- Compliance with applicable U.S. federal and state regulations
- Proper EPA RCRA/used-oil tracking and disposal procedures
- Comprehensive warranties
⚠️ If an operator cannot show you the USIFDA Mark, do not use their services. They are not certified and may cause further damage or legal issues.

Step-by-Step Guide
Step 1: Stop Immediately
If you realize you've misfueled before starting the engine, you're in the best possible situation. Do not start the engine under any circumstances. If you've already started the engine, turn it off immediately and do not restart it.
Step 2: Secure Your Vehicle
If you're at a gas station, move your vehicle to a safe location away from fuel pumps if possible (without starting the engine - you may need to push it or have it towed). If you're on the road, pull over safely and turn on your hazard lights.
Step 3: Contact a Certified Operator
Contact a USIFDA-certified operator immediately. Only operators displaying the USIFDA Mark are authorized to provide misfuel remediation services. They will:
- Arrange safe transport of your vehicle to their certified fixed facility
- Perform proper fuel extraction and system remediation
- Provide complete documentation and warranties
- Ensure compliant waste disposal
Remember: Only use operators displaying the USIFDA Mark. Currently, all certified operators operate from fixed facilities. Learn why certification requires a governing body.
Step 4: Understand the Process
Certified operators will:
- Transport your vehicle to their certified fixed facility (if needed)
- Extract all contaminated fuel using certified equipment
- Flush and clean the entire fuel system
- Replace affected components per manufacturer specifications
- Test the system to ensure proper operation
- Provide documentation and warranties
Step 5: Verify Certification
Before engaging any operator, verify they display the USIFDA Mark. Ask to see their certification. If they cannot provide proof of USIFDA certification, do not use their services.
Important Information
Your Legal Responsibility
Under U.S. law, you are responsible as the RCRA generator of contaminated gasoline or diesel for ensuring it is handled by properly licensed and insured operators.
Using non-compliant or uninsured operators can result in:
- EPA and state fines for improper hazardous waste or used-oil handling
- Liability for environmental violations if waste is improperly disposed
- Responsibility for cleanup costs if environmental damage occurs
- Denied auto insurance claims if remediation is performed by unqualified shops
- No practical recourse if work is performed incorrectly
✅ Protect yourself: Only use operators displaying the USIFDA Mark.
Insurance & Auto Claims
If you carry comprehensive or collision coverage, contact your insurer before authorizing repairs. Your deductible may apply. Ask for a written estimate and keep records for your claims adjuster. Misfuel remediation may be covered when performed at a certified facility using OEM-prescribed methods — coverage depends on your policy.

U.S. consumers are protected by:
- FTC Act Section 5 — unfair or deceptive practices; file complaints at ftc.gov
