Valero Investment Recovery Opportunities
Making Products from Gasoline to Asphalt

Valero’s refineries produce gasoline, diesel, jet fuel, asphalt, petrochemicals, lubricants and other refined products.

  • Key to Valero’s success has been its ability to upgrade and expand refining operations to produce high-value, clean fuels from a wide variety of crude feedstocks – two-thirds of which come from discounted feedstocks.

Processing a Variety of Crude Stocks

As an independent refiner, Valero does not drill for oil. It purchases a variety of feedstocks and is able to adjust its feedstock mix based on market conditions.

  • Valero acquires crude oil from producing leases, domestic oil trading centers and ships delivering cargoes of foreign and domestic oil.
  • Heavy sour and residual oil; medium sour oil; and light sweet and other oil each represent about one-third of the feedstocks.
Improving with Clean Technologies

Valero has made significant expenditures to produce cleaner-burning gasoline, diesel and ethanol-blended fuels. The company understands the importance of employing latest technologies and pursuing alternative-energy opportunities.

  • Valero’s low-sulfur gasoline program reduces sulfur emissions from cars and allows new automobile technology to reduce emissions of nitrogen oxide and hydrocarbons. Valero’s low-sulfur diesel program achieves similar reductions.
  • Valero has installed state-of-the-art "scrubbers" at most refineries that dramatically reduce sulfur dioxide emissions from Fluidized Catalytic Cracking Units, central units in the refining process.
Safety is Valero's Priority
Safety, both occupational and process, is integrated into every facet of operations, resulting in recordable-injury rates that are among the lowest in the industry.
