The most recent wholesale reads from EIA's daily ULSD spot series date to July 20: New York Harbor at $4.118/gal and the Gulf Coast hub at $4.039/gal. Those are untaxed bulk prices, not pump prices, and they predate this week's retail read by one week. WTI crude (Cushing) stood at $84.38/bbl and Brent (Europe) at $86.99/bbl on that same date per EIA's daily spot series. Crude is roughly half the cost of a gallon at the pump and reaches the retail price with a lag of days to weeks.

The US DOE number sits 40% above its 5-year median for this calendar week.
