How to estimate fuel for a trip

Gallons = miles ÷ MPG. Multiply by the diesel price you expect to pay. For reefers, add the gallons the unit burns per hour times the hours it runs.

Questions

What MPG do semi trucks get?

Many modern tractors average roughly 6 to 8 MPG loaded, but it varies with weight, speed, terrain, weather and the truck.

How do I find my real MPG?

Divide the miles driven by the gallons bought over a few fill-ups. An app that logs fuel receipts does this automatically.

Is fuel deductible?

Fuel for your business truck is generally a deductible business expense. Ask your tax preparer what applies to you.
