OptiMile Pro’s fuel planning platform is now available for fleets, including over-the-road trucking fleets and other fleets that operate across state lines. Some fleets still plan fuel manually, rely on driver habits, or use basic fuel-price visibility that doesn't account for the full cost of the trip.

OptiMile Pro replaces all three with a globally optimized fuel plan generated before the truck rolls. It tells dispatchers and drivers exactly which stops to make and how many gallons to load at each one, based on the carrier's contracted rates, the route, tank capacity, detours, trip requirements, each driver's actual MPG, and nearly 50 other variables.

Early customers are seeing fuel cost reductions of 11 to 17%, OptiMile reported. Across the U.S. trucking industry, which burns roughly 38 billion gallons of diesel a year, that range represents more than $20 billion in annual fuel spend that fleets pay for but don't have to. OptiMile said the platform also collapses fuel planning from hours to seconds, freeing dispatch teams from a task most still do on spreadsheets.

The "Fill Up When Empty" Problem

OptiMile said some fleets still fuel the way they did 20 years ago: drivers top off the tank when it gets low, at the closest station along the route.

Even fleets with sophisticated fuel networks and negotiated discounts leave money on the table on every run, OptiMile said, because the choice of where and how much to buy is made by gut feel rather than optimized across every trip.

“If your drivers fill up when they're nearly empty, there's a 100% chance you're spending more than you have to on fuel,” said Preston Reynolds, founder of OptiMile Pro. “Building a truly optimized fuel plan means evaluating millions of stop-and-fill combinations across every route, with prices that change daily and a different state-tax math at every border. The math is simply too complex for humans to do reliably, so most fleets settle for ‘good enough’ and end up spending up to 30% more than they need to.”

How OptiMile Pro Works

OptiMile Pro connects to a fleet's existing fuel contracts (including major networks like Love's Travel Stops, Pilot Flying J, and TA/Petro) and applies a one-of-a-kind globally optimal algorithm across every route. The platform doesn't just pick the cheapest station; it determines the precise amount of fuel to load at each stop, so the truck reaches the next station that's cheaper per gallon.

Here are three recent routes that were run on the platform:

• Seattle, Washington, to Dallas, Texas: $799 saved, 27.9% below the carrier's baseline cost
• Long Beach, California, to Syracuse, Utah: $252 saved, 32.3% below baseline
• Salt Lake City, Utah, to Denver, Colorado: $133 saved, 35.8% below baseline

State fuel taxes are part of the math, too.

Under the International Fuel Tax Agreement (IFTA), interstate carriers pay fuel tax based on miles driven per state, not gallons purchased there. OptiMile said that means the price posted on the pump isn't the real cost of fuel.

With diesel hitting record highs near $5.50 per gallon nationally, that gap matters more than ever. Between a station in Illinois posting $5.42 per gallon and a station in Indiana posting $5.55 per gallon, generally looks like an easy choice for most dispatchers. After IFTA tax adjustment, though, Illinois at roughly $0.43 per gallon in state tax, Indiana at roughly $0.61, the Indiana station is actually cheaper at $4.94 versus $4.99 on a true-cost basis.

OptiMile Pro applies that math automatically to every stop on every route, then layers fill-amount optimization on top. Once the plan is generated, OptiMile Pro delivers fuel instructions to drivers by SMS. Quickly coming features will also tell operations teams how well drivers are adhering to the plan.

“Fleets have more fuel data than ever, but data alone doesn't produce the cheapest plan,” Reynolds said. “OptiMile Pro turns route, truck, and fuel-network information into clear instructions that dispatch teams and drivers can actually follow to save piles of cash from being burned unnecessarily.”

What OptiMile Pro Handles for You

OptiMile Pro is designed to fit inside a fleet's existing operations. No new hardware. No driver retraining. No change to fuel contracts, dispatch software, drivers, routes, or delivery schedules.

OptiMile’s team will even handle the integration work for your fleet and connect the platform to the carrier's existing TMS and telematics systems directly. The only thing that changes operationally is which fuel stops drivers visit within the carrier's network, and how much they buy at each one.

30-Day Money-Back Guarantee

OptiMile is backing the launch with an unusual guarantee for B2B SaaS: if a fleet does not realize measurable fuel savings exceeding its OptiMile Pro subscription cost within the first 30 days, the fleet doesn’t pay anything.

“If we can't help a fleet make noticeable savings on their own routes in their first month, we don't deserve their money,” Reynolds said.
