Notable moves from the same EIA on-highway diesel survey:
- Midwest (PADD 2): $5.623/gal, down 2% on the week, 51% above its 5-year median. Spring planting season is the seasonal backdrop in the region, and the Midwest carries the widest above-median gap in the survey.
- Gulf Coast (PADD 3): $5.045/gal, down 2% on the week, 43% above its 5-year median. Anchors the low end of the regional map.
- California: $7.182/gal, down 1% on the week, 46% above its 5-year median.
- West Coast (PADD 5): $6.500/gal, essentially flat on the week. The West-vs-Gulf gap holds at 145.5 cents/gal, with the West Coast paying that spread over the Gulf Coast.
- Rocky Mountain (PADD 4): $5.493/gal, down 1% on the week, 41% above its 5-year median.
At the wholesale layer, Gulf Coast ULSD spot settled at $3.857/gal on May 22 (the nearest business day) per EIA's daily spot series. New York Harbor ULSD settled at $3.957/gal the same day. Both are untaxed bulk prices, not pump reads. The retail-minus-spot gap against the Gulf Coast hub sits at $1.666/gal, a proxy for the full hub-to-pump spread including taxes and distribution, not a station margin.
The national number stands 45% above its 5-year median for this calendar week. Every region in the survey runs at least 38% above its own 5-year median.
