How to File a Complaint Against CITGO

Customers experiencing a problem involving a CITGO-branded station, fuel quality, loyalty program or consumer interaction should identify the specific station and transaction before contacting the company.

Step 1: Contact the Station

If the issue occurred at a CITGO-branded gas station, contact the location and ask to speak with the station owner or manager because individual locations are independently operated.

Step 2: Keep the Receipt

Retain the fuel receipt, transaction record and station address so CITGO can identify the branded location.

Step 3: Contact CITGO Customer Service

Call 1-800-423-8434, Option 1 and provide the station, transaction and complaint information.

Step 4: Submit the Online Contact Form

Use CITGO’s official Contact Us page and select the topic that best matches the complaint.

Step 6: Follow Up With Customer Service

If the initial response does not resolve the concern, follow up through CITGO Customer Service and provide the prior case information.

Step 7: Request Additional Review

Ask whether the issue can be reviewed by the appropriate fuels, branded-retail or corporate team.

Step 8: Handle Emergencies Separately

For a pipeline or terminal emergency, call 1-800-471-9191 immediately rather than submitting an ordinary consumer complaint.
