  Values shown for the current month for regular gasoline at the U.S. and PADD levels in the retail outlets and sales for resale categories are initial estimates calculated using prior history of the series as well as present and past values of other related time series. For all other data, values shown for the current month are preliminary. Values shown for the previous month may be revised to account for late submissions and corrections and are considered final. Annual averages will be available in the April Petroleum Marketing Monthly. " Sales to End Users, Average" includes sales through retail outlets as well as all direct sales to end users that were not made through company-operated retail outlets, e.g., sales to agricultural customers, commercial sales, and industrial sales. Beginning January 2007, oxygenated gasoline is included in conventional gasoline.
