Valero’s business is refining and marketing, and the company offers many high-quality fuel products to its customers as well as opportunities for business partners and suppliers. Investing in technologies to make cleaner-burning gasoline, diesel and ethanol-blended fuels is what Valero does. Back in 2000, Valero was a small, independent refiner with 350 retail locations. Today, it is North America's largest refiner, with more than 4,000 Valero-branded retail locations coast to coast. Valero offers quality gasoline, pay-at-the-pump convenience and quick and friendly service.
