Where to fill
Outbound, fuel in Texas. Coming back, same state.
California to Texas: Texas is state 4 of 4 on the path and carries the lowest median. Texas back to California: it is state 1 of 4, so the fill lands earlier in the run. Either way, a 250-gallon fill in Texas runs about $540 less than the same fill in California.
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.
