Mr.Diesel

Fuel vendor comparison and route optimization for fleets

Know who's cheapest.
Fuel there.

Upload the price files your fuel vendors send. Mr.Diesel shows which card wins where your trucks actually run, then plans every stop on the road ahead.

Sample data for illustration. Prices are not real quotes. Vendor names are trademarks of their respective owners.

Fuel is a quarter of what it costs to run a truck. A few cents a gallon is real money.

3¢

per gallon between two vendors at the same exit is normal. It never shows on a price sheet.

$60

a month on that gap for one truck burning 2,000 gallons. Ten trucks, $600.

2 cards

often beat one. The cheaper vendor changes state to state, and we show you where.

What you get

Three answers you can act on today.

Which vendor wins

Every price file read the same way, PDF or spreadsheet. Vendors are compared only where both have a stop within 30 miles, so a cheap pump in one state never counts for a truck in another.

  • Cheapest card, state by state
  • What a second card is worth, and where
  • A written read-out with the numbers

Every stop on a map

Each truck stop from your files, placed at the pump, with today's price on the pin. Zoom to a town and see who is cheaper there.

  • Price on every pin
  • Real stop locations, not town centres
  • Directions in one tap

The stops for this run

Type where the truck is and where it is going. Set the fuel in the tank and the hours on the clock. Get the stops, the gallons at each, and where the day ends.

  • Truck routing, not car routing
  • Fits the driver's ELD hours
  • Send the plan to the cab

How it works

Ten minutes, once a week.

  1. Drop in the files

    The price sheets your vendors emailed this week. Any format. Tell us who sent each one.

  2. Read the answer

    Who wins, where, and what it is worth a month at your gallons. One screen.

  3. Plan the runs

    Type a route. Get the stops. Copy the plan to the driver.

Then check what you actually paid

Upload a fuel card statement. Every fill is priced against the cheapest stop that was in reach, and the difference is totalled by driver, by truck and by vendor.

Independent

We don't sell fuel. We don't take a cut. We don't sell your data.

Mr.Diesel is not a fuel card, not a network and not a broker. No vendor pays to be ranked. Your files stay yours. Every number on the screen is one you can check against the sheet in your hand.
