Gladiator MPG Questions
Which Gladiator year gets the best gas mileage?
The 2021 to 2023 Gladiator EcoDiesel 4WD holds the top EPA rating at 24 MPG combined (22 city, 28 highway). Among 2026 models, the Gladiator 4WD is rated at 19 MPG combined.
Why doesn't my Gladiator match the EPA numbers?
EPA tests assume about 300 pounds of passengers and cargo, flat roads and no trailer, and four-wheel-drive trucks are tested in two-wheel drive. Towing, hauling, hills, idling, speed, cold weather and tire pressure all pull real-world numbers down. Use the ratings to compare one truck with another, and track your own with the MPG calculator.

Where These Numbers Come From
This page was built by Cedrick Reese from the U.S. EPA fuel economy dataset on fueleconomy.gov, which holds 17 ratings for the Jeep Gladiator from 2021 to 2027. Each row in the table links to the matching EPA vehicle record, so you can check any figure against the source. The page is rebuilt whenever the EPA publishes an updated file, which picks up new model years and any rating corrections. The cost calculator uses the gas price you enter rather than a national average, so the result fits where you live.
Ratings on this page come from the EPA file downloaded on October 1, 2026.
