EIA national context (week ending July 13)

For broader context, the U.S. Energy Information Administration’s latest weekly retail update shows U.S. regular gasoline at $3.855/gal for the week ending July 13, up $0.078/gal versus the prior week. U.S. on-highway diesel averaged $4.796/gal for the same week, up $0.218/gal week-over-week. (EIA gasoline and diesel release date: July 14, 2026.)

What this means for local drivers, delivery, and contractor budgets

For commuters and households: today’s regular-gas shift is small, but it matters over repeated weekend trips and weekday commuting. Diesel, meanwhile, is showing a near-steady day-to-day pattern in the AAA metro average—so planning work routes and schedule fuel needs may be slightly more predictable than gasoline.

For contractors and delivery drivers: diesel is still well above year-ago levels in the Milford–Seaford average. If you track fuel costs for estimates, compare today’s metro reference ($4.790/gal) against your last invoice cycle rather than guessing from national headlines.

What to watch next

Because diesel is nearly flat versus yesterday while regular gas is higher, watch whether the “gap” between gas and diesel widens or tightens over the next few AAA updates—especially if you’re fueling both personal vehicles and work fleets.
