How to Use an RV MPG Calculator: A Step-by-Step Guide

Calculating your RV’s MPG is straightforward. You don’t need fancy equipment, just a pen, paper, and your RV’s odometer. Here’s your practical rv mpg calculator guide.

Step-by-Step Fuel Efficiency Calculation

  1. Fill Your Tank Completely: Head to a gas station and fill your RV’s fuel tank until the pump automatically clicks off. Do not “top off” excessively.

  2. Record Your Starting Odometer Reading: Note the exact mileage on your RV’s odometer. This is your baseline.

  3. Drive as Usual: Enjoy your trip, whether it’s a short jaunt or a long cross-country journey. Drive normally, as you would for any adventure.

  4. Refuel Again (Full Tank): When it’s time to refuel, go back to the pump and fill the tank completely once more. Note the exact number of gallons you put in.

  5. Record Your Ending Odometer Reading: Take down the current mileage from your odometer.

  6. Perform the Calculation:

    • Calculate Miles Driven: Subtract your starting odometer reading from your ending odometer reading. For example, if you started at 10,000 miles and ended at 10,250 miles, you drove 250 miles.

    • Divide by Gallons Used: Take the total miles driven and divide it by the number of gallons you just put into the tank. If you drove 250 miles and added 25 gallons, your MPG is 10 (250 / 25 = 10).
