The world’s most comprehensive source for petroleum information, products & prices began in 1977 with the award-winning Oil Express Newsletter, quickly expanded in 1980 into the only source, and the world’s most comprehensive database of U.S. wholesale petroleum prices. We now distribute the most accurate, reliable and referenced petroleum prices via fax, newsletter, e-mail, Internet, 3rd party vendors, and through one of the nation’s first commercial on-line services — PetroScan. OPIS is comprised of more than 40 information specialists, including the most experienced editors and pricing experts in the business. Pricing experts track more than 70,000 rack prices for heating oil, gasoline, diesel and kerosene, and thousands of contract prices for jet fuel, LP-gas, residual fuel, and ethanol. More than 85,000 retail gasoline prices are also tracked daily. Our editors not only cover the market, and report breaking stories — but also provide inside analysis on what the trends mean and how they could affect prices and purchasing decisions. Our client list is strictly confidential, and includes the top 200 oil companies, thousands of distributors, traders, government and commercial buyers of petroleum products.
