You Negotiated Great Fuel Contracts. You're Still Overpaying by 27%.
Direct Answer
Negotiating great fuel contracts only captures part of the available savings. When drivers pick their own contracted stations, fleets routinely lose 27% of the negotiated discount because the first contracted station on a route is rarely the cheapest. For a 50-truck fleet, this gap typically equates to $300,000–$500,000 per year in unrecovered savings.
Key Statistics
- Driver-chosen stops typically forfeit ~27% of the negotiated contract discount.
- A 50-truck fleet leaving 27% of the contract savings on the table loses $300K–$500K per year.
- Within a single contract network, same-day station price spreads of $0.18–$0.31/gal are common.
The hidden cost of "driver's choice" fueling and the simple fix that's saving fleets 15%+ per route.
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 might be $0.35/gallon cheaper than 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
We ran real routes through our optimization engine. Not hypotheticals. Not "up to" numbers. Actual contracted pricing, actual stations, actual miles.
Here's what we found:
Route 1: 4,796-mile run
Unoptimized fuel cost: $2,739
Optimized fuel cost: $2,002
Savings: $737 (26.9%)
Route 2: Same corridor, different week
Unoptimized fuel cost: $2,741
Optimized fuel cost: $1,987
Savings: $754 (27.5%)
Route 3: 6,893-mile run
Unoptimized fuel cost: $4,266
Optimized fuel cost: $2,833
Savings: $1,433 (33.6%)
Route 4: 1,989-mile run
Unoptimized fuel cost: $720
Optimized fuel cost: $509
Savings: $211 (29.3%)
Read those numbers again. That's not 3-5%, the kind of marginal improvement most "optimization" tools promise. That's 27-34% of your fuel spend on every route, sitting on the table because no one told your driver which station to pull into. And if you don't save at least 15% back, you don't even have to pay for your contract with us.
Scale It Up and the Numbers Get Uncomfortable
Let's do the math for 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
If you're overpaying by even 27% on fuel stop selection, the low end of what we're seeing, that's $405,000 to $594,000 per year you're handing back.
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.
For a 35-truck fleet doing $18-22M in revenue, that 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? It's $0.12/gallon more expensive by Thursday. 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. It just happens to cost you $700 per run.
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:
- Your contracted fuel pricing: the rates you negotiated with Love's, Pilot, TA/Petro, whoever
- Your routes: where your trucks are already going
- 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.
Our Guarantee
11-17% fuel savings in your first month, or your money back.
We guarantee the conservative number. What we actually see in the data is 27-34%. Every route we've analyzed has come back above 25%.
Why guarantee the lower number? Because we'd rather under-promise and over-deliver. And because we know some fleets have tighter route corridors, fewer station options, or already do some informal optimization. Even in those cases, 11-17% is a no-brainer.
If we don't hit it, you pay nothing. You keep the data. No hard feelings.
The Real Risk Is Doing Nothing
You didn't build a $20M 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 $8,000-$11,000 in fuel savings you're not capturing. Not theoretical savings. Real dollars, from routes you're already running, at stations you already have contracts with.
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.
