The spread
What the $0.70 spread means for a fleet.
Stations in Delaware range from $5.82 at the cheap end to $6.52 at the expensive end. On a single 250-gallon tractor fill, the difference between a cheap-end station and a median-priced one is about $126, on one fill, for one truck, before any negotiated discount is applied.
That spread is exactly where fuel optimization earns its keep: ValveRide Flow routes every dispatch to the right stop for the route, applies your negotiated contract rates on top of the posted price, and accounts for state fuel-tax differences so the net cost, not the pump sign, drives the decision.
