    Your Fuel Contract Sets the Price. Your Route Decides What You Pay.

    Direct Answer

    Your fuel contract sets the price at every station in the network. Your route decides which of those prices you actually pay. Same-day contracted prices inside one network commonly vary $0.18–$0.31 per gallon, so the station a driver picks, not the contract, decides where on that spread the fleet buys. Route-aware fuel-stop selection saves an average of 11% of fuel spend per load without renegotiating anything.

    Key Statistics

    • A fuel contract sets the price at each station in the network. It does not decide which station the truck stops at, and that decision is made again on every route.
    • Within a single contract network, same-day station price spreads of $0.18–$0.31/gal are common.
    • Route-aware contract selection saves an average of 11% of fuel spend per load, using the contracts you already negotiated.

    The hidden cost of "driver's choice" fueling, and the simple fix that closes the gap between the price you negotiated and the price you actually pay.

    You fought for those fuel discounts. You sat across the table from Love's, Pilot Flying J, TA/Petro ... whoever your network is ... and you ground out every fraction of a cent per gallon. You've got contracted pricing that your competitors would love to have.

    And you're still lighting money on fire every single week.

    Not because the contracts are bad. Because nobody's optimizing where your trucks actually stop and how much they buy when they stop.

    The Contract Is Only Half the Equation

    Here's what most fleet owners get right: they negotiate volume discounts with major fuel networks. We're talking honestly good rates that lead to real savings versus retail.

    Here's what almost every fleet gets wrong: they assume the contract does the work.

    It doesn't. Your contracted rate at a Love's in Amarillo is not your contracted rate at the Love's 90 miles down the road. Same network. Same contract. Different station-level pricing. And your driver, who's tired, hungry, and just wants to park somewhere decent, picks whichever one he hits first.

    That's not a driver problem. That's a systems problem. And it's costing you a lot more than you think.

    What "Driver's Choice" Actually Costs

    The honest answer is that it depends on your lanes, your network and where your drivers happen to stop, which is why the useful version of this exercise is the one you run on your own data rather than one you read about.

    Here is the shape of it. Take one run you already dispatched. Line up what the truck actually paid, station by station, against what the same run would have cost buying the same gallons at the cheapest contracted stations on that corridor that day. Same route. Same contract. Same driver. The only thing that changed is which station he pulled into and how many gallons he bought once he was there.

    Do that for a month of runs and the gap stops being an argument. It is arithmetic over your own receipts, and it is either there or it isn't.

    Now Scale It Across the Fleet

    Now hold that against a fleet like yours.

    Say you're running 35 tractors. Each truck runs roughly 100,000-120,000 miles per year. Your annual fuel spend is somewhere around $1.5-2.2 million, depending on your lanes and fuel prices.

    The Bottom Line

    Every mile of that gets fueled somewhere, and every fill lands at whichever contracted station the truck reached first. The gap between that station and the cheapest one your contract already covers is money you negotiated for and never collected.

    Not to your competitors. Not to your drivers. To nobody. It just evaporates because the driver stopped at the wrong station on the wrong day.

    Recovered fuel cost drops straight to your bottom line. No new trucks. No new lanes. No new customers. Just stop overpaying for diesel you already have a contract for.

    Why Spreadsheets and "Fuel Policies" Don't Fix This

    You've probably tried some version of solving this already. Maybe you told drivers to "always fuel at Love's." Maybe dispatch sends a list of preferred stops. Maybe you've got a sharp ops manager who tries to plan fuel stops manually.

    None of it works at scale. Here's why:

    Station pricing changes daily.

    That Love's in Oklahoma City that was cheapest on Monday? By Thursday it isn't. Your spreadsheet is already wrong.

    The math is combinatorial.

    On just a 5-stop route, the number of possible station combinations within your fuel network is in the thousands. No human is running that optimization in their head ... or even in Excel.

    Drivers make reasonable choices.

    Your driver isn't lazy. They're just picking a station that's convenient, one that they know, one that has parking. They don't have real-time pricing for every station within 25 miles of their route. So they do what makes sense to them, and it costs you on every run that nobody planned.

    What OptiMile Pro Actually Does

    We're not changing your routes. We're not renegotiating your contracts. We're not putting another screen in your driver's cab.

    We take three things you already have:

    1. Your contracted fuel pricing: the rates you negotiated with Love's, Pilot, TA/Petro, whoever
    2. Your routes: where your trucks are already going
    3. Your fuel networks: the stations your contracts cover

    Then we analyze every qualifying station within 25 miles of each route corridor, factor in real-time pricing under your contracts, and calculate the optimal fuel stop sequence. Which stations. How many gallons at each. In what order.

    The output is simple: a fuel plan your driver can follow. Pull in here, fuel this much, get back on the road.

    It's That Simple

    No route changes. No contract changes. No driver retraining. No hardware installation. No six-month integration project. We'll have you up and running in the same week, if not the same day.

    The Guarantee: We're Not Asking You to Trust Us

    Look ... you've heard optimization pitches before. Every vendor claims they'll save you money. Most of them are selling you a dashboard and a prayer.

    ROI in Your First Month or We Refund Your Subscription

    If OptiMile Pro doesn't deliver measurable fuel savings that exceed your subscription cost in the first 30 days, we'll refund every dollar. No questions, no hoops.

    You keep the data either way. No hard feelings.

    The Real Risk Is Doing Nothing

    You didn't build this fleet by intentionally leaving money on the table, but that's exactly what's happening every time a truck rolls out without an optimized fuel plan.

    Every week you wait is another week of runs fueled at whichever contracted station the driver reached first. Not theoretical money. Real dollars, from routes you're already running, at stations you already have contracts with, and there is no way to go back and re-buy last week's gallons.

    Your competitors are going to figure this out. The ones running tight margins are going to find tools like this and use them to undercut you on rates. The question isn't whether fuel stop optimization becomes standard practice. It's whether you're early or late.

    See Your Own Numbers

    We'll run your actual routes through our engine, free. No commitment. No sales pitch. Just your routes, your contracted pricing, your numbers.

    You'll see exactly how much you're overpaying per route, per truck, and per year. Then you decide.

    Takes 10 minutes to set up. You'll have results the same day. And if the numbers don't make you pick up the phone, we'll leave you alone.

    That's the OptiMile Pro promise: show you the money first, earn your business second.

    OptiMile Pro optimizes fuel stop selection for trucking fleets with 10-250 tractors. We use your existing fuel contracts and routes to eliminate overspending at the station level. No route changes. No contract changes. Just smarter stops.

    Frequently Asked Questions

    The contract fixes the price at each station in the network. It does not choose the station. Within one network, same-day contracted prices commonly vary $0.18–$0.31 per gallon, so which station a driver stops at still moves the fuel bill on every route.

    A contract sets the discount level at each station, but it doesn't decide which station the driver uses. Route-aware selection is the part that chooses, against today's contracted prices, and it works entirely inside the contracts you already hold.

    Same-day contracted prices within a single network commonly vary $0.18–$0.31 per gallon, driven by regional pricing, state tax differentials, and station-level economics.

    An average of 11% of fuel spend per load. The savings calculator on the pricing page runs the same arithmetic against your own truck count, mileage, and MPG.

    Usually not. The fix is route-aware contract selection, which uses your existing contracts to pick the best contracted station on each route. Renegotiation is a separate (and slower) lever.
