From a report by the Ministry of Economy of El Salvador:

The United States reported its second increase in its oil inventories on February 7 of this year, in which its production reached a record of 10.25 million barrels per day (bpd) in the last week, as reported by the U.S. Energy Information Administration (EIA); where an 11 week downward streak was reversed, affected by low temperatures and the holiday season.

As a result, distillate stocks, including diesel and heating fuels, rose by 3.9 million barrels per week, compared to the expectation of a 1.4 million barrel per week drop, allowing for slight drops in diesel and distillate prices.
