19 MPG combined. Nobody buys a 2020 Jeep Gladiator expecting Prius-like fuel economy. This is a mid-size pickup truck with solid axles, designed to conquer trails and look good doing it. The fuel consumption is the price of admission to the Gladiator club.

City and highway performance

The EPA estimates for the 2020 Jeep Gladiator, equipped with the 3.6L V6 and 8-speed automatic transmission, are 17 MPG in the city and 22 MPG on the highway. The city figure is the more painful one; stop-and-go traffic and the Gladiator’s considerable weight impact fuel economy. Highway driving allows the engine to settle into a more efficient cruising speed. Adding larger, heavier off-road tires and aftermarket accessories will further degrade these numbers.

Annual fuel cost

According to the EPA, the estimated annual fuel cost for this Gladiator configuration is $2,300. This calculation is based on driving 15,000 miles per year and using national average fuel prices. Fuel prices fluctuate, and your personal driving habits will significantly impact your actual fuel expenses. If you primarily use your Gladiator for short trips around town, expect to spend considerably more than the EPA estimate. Longer highway commutes could potentially result in lower costs.

Real-world expectations

EPA numbers provide a baseline, but real-world MPG often differs. This is especially true for vehicles like the Gladiator, where driving style and terrain dramatically affect fuel consumption. Owners who frequently engage in off-roading, tow trailers, or drive aggressively will likely see numbers closer to the low end of the spectrum (15-17 MPG combined). Those who primarily use their Gladiator as a daily driver and adhere to posted speed limits might achieve numbers closer to the EPA estimates. Consistent monitoring is key to understanding your individual fuel consumption.

How it compares

Compared to its competitors, the 2020 Jeep Gladiator fares predictably poorly. The Toyota Tacoma achieves 20 MPG combined in its 4WD V6 configuration, even though that Toyota’s engine doesn’t offer as much horsepower or torque. The Chevrolet Colorado with the V6 and 4WD clocks in at 20 MPG combined, and the Ford Ranger with its 2.3L EcoBoost turbo manages a respectable 22 MPG combined. The Gladiator’s fuel economy is a conscious tradeoff for its Wrangler-derived styling, removable top and doors, and superior off-road capabilities. These features justify its lower efficiency for many buyers. If maximizing fuel economy is your top priority, there are better choices. But if you crave open-air freedom and trail-ready performance, maybe you’ll make a quick detour and review GLADIATOR MPG across all years.

Tips to maximize efficiency

While the Gladiator isn’t known for its fuel efficiency, a few strategies can help you squeeze extra miles out of each gallon. Minimize unnecessary idling, as the engine consumes fuel even when the vehicle isn’t moving. Avoid aggressive acceleration and braking, as these habits significantly reduce fuel economy. A smoother, more gradual driving style is key.

Keep your tires properly inflated to the recommended pressure. Underinflated tires create more rolling resistance, which forces the engine to work harder and consume more fuel. Regularly check your tire pressure, especially during seasonal temperature changes.

Reduce the vehicle’s weight whenever possible. Remove any unnecessary items from the bed and interior of the truck. The heavier the vehicle, the more fuel it takes to move it. Extra gear adds up quickly.

Consider using cruise control on the highway. Maintaining a consistent speed can improve fuel economy, particularly on long drives. However, be mindful of traffic conditions and adjust your speed as needed. Also, check out all Jeep fuel economy data.

Ensure that your Gladiator receives regular maintenance, including oil changes and air filter replacements. A well-maintained engine runs more efficiently and consumes less fuel. Following the manufacturer’s recommended maintenance schedule is essential for optimal performance and fuel economy.
