Strong refining margins indicate the value of processing scarce products relative to input costs, not a measured profit for every refinery after operating expenses.","For freight operators, this makes a diesel-linked adjustment more informative than a crude-only comparison. Contract users should check whether the fuel clause uses a weekly retail average, a wholesale index or an agreed terminal price, and how quickly that reference enters invoices.
