Know where, when, and how much every truck should fuel.
FuelGuru turns fuel state from telematics, fleet-net prices, route economics and fleet policy into an executable fuel prescription: where to stop, when to stop, and how many gallons to buy. As the trip changes, FuelGuru recalculates the plan and measures what actually happened.
The economic decision engine behind every fuel stop.

The prescription says where to stop and how much to buy.
Negotiated prices, taxes, detour and route cost.

Why fuel optimization still leaks money
The fuel plan is built on assumptions
Tank levels, prices and routes change after dispatch. Prices can change several times a day. A plan built at 9am for a 4pm fill can already be stale.
The cheapest pump may not be the cheapest stop
Detour, tax, toll and the next fueling opportunity change the answer.
The plan often never reaches the driver
A prescription in a back-office report cannot create savings. At one 2,500+ truck carrier, only 74% of prescriptions were followed before the plan moved into the driver's navigation.
Nobody measures prescription vs execution
Fuel-card spend shows what was bought, not what should have been bought.
A prescription, not a recommendation.
Per trip: ordered stops with the station, the expected arrival time, the gallons to buy, the price at your card rate, and the detour to get there. "Go to this station" is a recommendation. "Buy 62 gallons here, then 108 at the next preferred stop" is a prescription.
How much to buy comes from the fuel already on board, the reserve you require at arrival, the route ahead, the price opportunities on it, tank capacity and fleet policy. Sometimes the best fill is not a full fill.
- ✓ In your fleet network
- ✓ $0.17/gal advantage at your card rate
- ✓ Inside the 2-mile out-of-route policy
- ✓ Better next-stop economics
The cheapest pump is not always the cheapest stop.
Four effects stack. Most of them are invisible to anything reading a public price feed.
The rate your fuel program actually gives you at that location. Not the sign price, not a national average.
Station prices normalized for state fuel taxes and IFTA, so stops in different states are compared on what the fleet actually pays.
The miles and minutes to reach the station, priced against the pump saving and held inside your out-of-route policy.
Hours of service are in the plan, so each stop uses the latest pricing applicable to the truck's planned arrival window, not the file that happened to be available at dispatch.
Your fuel strategy, on every trip.
Set the policy once. FuelGuru applies it consistently across every eligible trip. Full or partial fill, the out-of-route cap, preferred networks and contracted pricing locations, penalties for stops set back from the highway, and stops a fuel manager has disabled.
Disable a stop once and every affected trip re-prescribes. Nobody has to call.
The best fuel stop is the one your driver will actually fuel up at.
A mathematically perfect stop that the driver skips saves nothing.
FuelGuru learns which stops drivers actually use.
Every stop carries a score built from observed behavior. FuelGuru prescribes where the score is high. When a location keeps getting skipped, that becomes a signal it may no longer be practical, even when the price looks attractive on paper.
FuelGuru decides. NavGuru executes.
The prescribed stop appears inside the driver's turn-by-turn with the station and the gallons. Not a separate app the driver is supposed to remember to check. If the stop becomes unavailable or the trip changes, the route and the fuel plan recompute together.
Keeping another in-cab surface? The prescription goes into your TMS trip plan or that surface instead.
See NavGuru →A fuel decision can change the economics of the entire route.
One dry-van lane, Harvey, Illinois to Philadelphia. FuelGuru priced six commercial routes on tolls plus fuel. The spread between them was $326 per load. The sharper finding was the price of time.
FuelGuru analysis of a Harvey, IL to Philadelphia, PA dry-van lane, published August 2026. Fuel prices, tolls and trip economics vary with timing, equipment, payment method and fleet configuration.
"Avoid tolls" is not a strategy. "Always take the toll road" is not a strategy either. Put a price on time, fuel and tolls, then decide.
FuelGuru returns practical, fastest, cheapest and alternate routes with drive time, vehicle-specific tolls, fleet-net fuel cost, prescribed stops and gallons, and total trip economics. FuelGuru prices the economics. NavGuru executes the chosen route in the cab.
Routes built on how your fleet actually drives.
A generic truck route knows the road network. It does not know your yards, your customers' gates, or the roads your drivers have learned to stay off. Your fleet's GPS history does.
Illustrative network. FuelGuru learns road preferences from each fleet's own historical GPS trips. Segment preferences set by a fleet admin apply to new routes and re-routes.
FuelGuru reads your fleet's historical GPS: the approaches, access roads and corridors your trucks actually use, and the ones they consistently avoid.
Know a road better than the data does? Prefer, avoid or block any segment.
The change applies the moment you save it, on the next route and every re-route. Nobody waits for a map update.
Every route, and every fuel stop priced along it, starts from your fleet's road network. Not a one-size-fits-all truck map.
Prescribe. Deliver. Adapt. Verify.
Prescribe
Combine the trip, current fuel state, fleet pricing and policy. Price every candidate stop. Return the route, stops and gallons.
Deliver
Put the prescription into NavGuru, the TMS trip plan or the driver's existing in-cab workflow. No navigation switch required.
Adapt
Missed stop, off route, lower tank than expected, prices moved. Recalculate from the truck's current state instead of forcing it back to a stale plan.
Verify
Match GPS and fuel-card transactions against the active prescription: stop, gallons, price paid and compliance, per driver, per stop, per trip.

“The utilization of GPS data, fuel-in-tank telemetry, and route planning allows the MapUp products for managing and auditing toll expenses, as well as fuel purchase planning. These tools afford us the opportunity to better utilize data in our edge environments to run a more efficient fleet.”
Works with the stack already running your fleet.
Three connections, set up once at onboarding: vehicle state, fuel economics and trip execution. Plus MapUp's licensed station-level price feeds, updated multiple times a day. No rip and replace.
GPS, tank level, odometer, vehicle state
Prices every candidate stop and route on your economics and policy. Prescribes stops and gallons. Verifies against transactions.

Give your dispatch agent the real economics of the trip.
MapUp introduced FuelGuru MCP in August 2026, bringing fleet-specific fuel, toll and commercial-route economics directly into dispatch agents, TMS copilots and load boards. The agent handles the conversation. FuelGuru handles the transportation math.
The first production Model Context Protocol server built for fleet-specific fuel purchasing, toll and commercial truck routing decisions. FreightWaves, 13 Aug 2026
Truck 1427 is in Nashville with 62 gallons. Load delivers tomorrow 08:00 in Charlotte. Which route keeps the most margin, and where should he fuel?
Responses come back as structured data, so a partner can drop the numbers into a ranking, a UI card or a voice answer. The same engine is available over the FuelGuru API.
Prove FuelGuru on trips you already drove.
You do not need to deploy FuelGuru, or change driver behavior, to find out whether the opportunity exists. Send historical trips, vehicle assumptions, fuel purchases and pricing. FuelGuru replays your top lanes and returns the prescribed routes, stops, gallons and modeled economics against what actually happened.
