The spread

What the $0.49 spread means for a fleet.

Stations in Iowa range from $6.20 at the cheap end to $6.69 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 $50, 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.
