CITGO

CITGO is the brand of CITGO Petroleum Corporation, an independent refiner that runs three refineries designed to process a broad range of crude oils. The company makes transportation fuels, lubricants, petrochemicals and solvents, and it also handles fuel supply and energy trading. Its gasoline is sold under the TriCLEAN name.

Most drivers know CITGO from the branded stations that sell its fuel, which are locally owned rather than run by the company. Club CITGO is the loyalty program, and Walmart+ members can redeem Walmart gas savings alongside it. Pipeline and terminal emergencies go to a separate 24/7 line, while general fuel questions go through the customer service contact on the company's site. A Pflugerville address is listed for the company, and its corporate headquarters is in Houston.
