Where to fill
Outbound, fuel in Oklahoma. Coming back, same state.
Michigan to Texas: Oklahoma is state 5 of 6 on the path and carries the lowest median. Texas back to Michigan: it is state 2 of 6, so the fill lands earlier in the run. Either way, a 250-gallon fill in Oklahoma runs about $125 less than the same fill in Illinois.
The state tells you where the price is; it does not tell you which exit, how many gallons the tank needs to reach it, or whether the IFTA math flips the answer. That is the per-dispatch work ValveRide Flow does automatically, with your contract rates on top of the posted price.
