About Diesel price vs crude oil
This gap is not the crack spread. A crack spread compares a wholesale refined product to wholesale crude. This is the RETAIL pump price minus crude, so it carries refining, distribution, station costs and federal and state fuel taxes all in one number, not just a refiner's margin.
Crude moves fastest. The pump follows with a lag of days to weeks as the new crude cost works through refining and distribution, so a crude spike this week shows up at the pump gradually, not instantly, and the gap often widens briefly right after a sharp crude move before it settles back.
A widening gap over a longer stretch, weeks rather than days, points at something other than crude: tighter refining capacity, a distribution bottleneck, or a tax change, since the crude cost is already netted out of this number. A narrowing gap points the other way, the pump catching up to a crude move that already happened, or refining and distribution costs easing.
WTI, converted to dollars per gallon by dividing by 42 (the gallons in a barrel), is the crude benchmark used here. See the WTI and Brent pages for the raw crude benchmarks on their own.
