    Does PC*MILER Optimize Fuel? What It Does and What It Doesn't

    Direct Answer

    No. Base PC*MILER is truck-legal routing, mileage, and IFTA mileage reporting; it does not optimize fuel purchases. Trimble's real fuel optimizer is Expert Fuel: genuinely capable, gallon-level, and IFTA-aware, but enterprise-only, quote-priced, and effectively tied to Trimble's TMS. OptiMile Pro delivers the same class of optimization as a self-serve SaaS with public per-truck pricing and no TMS lock-in.

    Key Statistics

    • Base PC*MILER produces truck-legal routes and the state-by-state miles you file IFTA on; it does not compute fuel purchases.
    • Trimble Expert Fuel is enterprise/quote-only and effectively requires Trimble TruckMate or TMW.Suite.
    • OptiMile Pro is $50–$75 per truck per month with public pricing, a 30-day free trial, and no TMS requirement.

    Two things people get wrong about Trimble and fuel. First: base PC*MILER does not optimize fuel purchases. Second: Trimble's real fuel optimizer — Expert Fuel — is excellent, but most fleets can't actually buy it. Here's the honest breakdown.

    The Myth: "We Already Have PC*MILER"

    Short answer: base PC*MILER does not optimize fuel on its own. It's the industry-standard engine for:

    • Truck-legal routing and dock-to-dock mileage
    • State-by-state mileage for IFTA filing — which is reporting, not fuel optimization
    • Toll cost calculation and truck-restriction-aware maps

    What it does not do in the base product is decide which stops and how many gallons to buy to minimize fuel cost. So "we already have PC*MILER" means you have best-in-class routing and IFTA miles — not a fuel-buy plan.

    Naming Note

    "Fuel Dispatch" is also not the optimizer — it's a Trimble TMS for companies that haul fuel to gas stations. The fuel-purchase optimizer for carriers buying their own diesel is Expert Fuel.

    Meet the Real Optimizer: Trimble Expert Fuel

    Credit where due — Expert Fuel is a capable enterprise fuel-purchase optimizer. It:

    • Sends drivers exact gallons per stop — buy the max where cheap, the min where expensive
    • Factors IFTA and state tax, out-of-route miles, and tank-fill policy
    • Validates driver compliance after the fact, flagging over-buys

    On optimization substance, Expert Fuel is a peer. The question isn't capability — it's who can actually deploy it, and at what cost.

    The Real Divide: Deployment, Not Math

    Expert Fuel lives inside Trimble's TMS suite and pushes plans through your in-cab mobile comms — powerful if you're already all-in on Trimble, a heavy lift and a lock-in if you're not. OptiMile Pro is a standalone SaaS that works alongside whatever TMS you run — McLeod, Alvys, Truckbase, and others — and your telematics (Samsara, Motive, Geotab). And we do the integration for you.

    Then there's who can buy it. Expert Fuel is sold enterprise-to-enterprise, quote-priced, oriented to large truckload fleets — if you're a small or mid fleet, it likely isn't sold to you at all. OptiMile Pro has public per-truck pricing and a self-serve free trial, so a 15-truck and a 150-truck fleet adopt it the same way.

    For McLeod (and Other TMS) Shops

    Worth knowing: McLeod doesn't build its own fuel optimizer — "fuel optimization through McLeod" usually means buying into the enterprise Expert Fuel stack. OptiMile Pro is the alternative that plugs into your McLeod-run operation without the enterprise commitment, and our team handles the connection.

    The Bottom Line

    If you're a large fleet standardized on Trimble's TMS with in-cab comms and an enterprise procurement team, Expert Fuel is a legitimate choice — it's a strong optimizer with compliance validation built in. For everyone else, the same class of gallon-level, IFTA-aware optimization is available without adopting a TMS, without a quote cycle, and without an implementation project.

    And the trial is genuinely free: your first month costs nothing, and if the savings don't show up, you never pay us.

    Enterprise optimization without the enterprise contract

    OptiMile Pro delivers gallon-level, post-IFTA fuel plans to your drivers by SMS — on your existing TMS and telematics, with the integration done for you. Start free, no credit card.

    Frequently Asked Questions

    No. Base PC*MILER does truck-legal routing, dock-to-dock mileage, toll costs, and IFTA mileage reporting. Deciding which stops and how many gallons to buy is a separate capability; Trimble's fuel optimizer is Expert Fuel.

    Fuel Dispatch is a TMS for petroleum haulers (fleets that deliver fuel to gas stations). Expert Fuel is the fuel-purchase optimizer for carriers buying their own diesel. They're commonly confused.

    Yes. It's a genuinely strong enterprise optimizer: exact gallons per stop, IFTA/state-tax aware, with built-in driver-compliance validation. The question isn't capability; it's deployment. It's quote-priced, enterprise-only, and effectively requires Trimble's TMS stack.

    Yes: comparable gallon-level, IFTA-aware optimization, but delivered as a self-serve SaaS with public per-truck pricing, no TMS lock-in, done-for-you integration, and SMS delivery to drivers, suitable for fleets of any size.

    No. OptiMile Pro works alongside your existing TMS and telematics (McLeod, Alvys, Truckbase, and others; Samsara, Motive, or Geotab), and the OptiMile team connects them for you.
