24 MPG combined is a figure that prompts a specific reaction from those considering the 2022 Jeep Gladiator EcoDiesel 4WD 3.0L. No one expects Prius-like efficiency from a midsize pickup truck designed for serious off-road adventures. Instead, the number represents a practical compromise: reasonable fuel consumption matched with the torque and capability demanded by a dedicated Jeep enthusiast and outdoor adventurer.

City and highway performance

While the combined figure is important for overall comparisons, the individual city and highway numbers tell a more detailed story. The Gladiator EcoDiesel manages 22 MPG in the city, reflecting the expected penalty for stop-and-go driving in a heavier, less aerodynamic vehicle. On the open highway, efficiency climbs to 28 MPG, showcasing the benefits of the diesel engine’s relaxed cruising ability and the eight-speed automatic transmission’s ability to find the optimal gear. These figures make extended road trips to trailhead access points significantly more palatable than with the standard gasoline V6.

Annual fuel cost

Owning a vehicle like the Gladiator isn’t solely about MPG; the annual fuel cost is also important. The EPA estimates this cost at $2,300 per year, based on driving 15,000 miles and using national average fuel prices. This figure is crucial because it provides a tangible dollar amount to factor into the cost of ownership. While diesel fuel prices can fluctuate, understanding this baseline allows potential buyers to budget accordingly. Remember, this estimate uses a specific mileage and fuel price; your actual costs will vary based on your driving habits and local fuel costs.

Real-world expectations

EPA estimates provide a valuable baseline, but real-world Gladiator EcoDiesel owners often experience figures slightly different from the official numbers. Factors like driving style, terrain, tire choice, and additional weight from aftermarket modifications significantly impact fuel economy. Owners who frequently engage in off-road driving or towing should expect lower MPG than the EPA estimates. Conversely, those who primarily use the Gladiator as a daily driver on paved roads might see numbers closer to, or even slightly exceeding, the highway figure. It’s also important to consider the impact of cold weather, which can negatively impact diesel engine efficiency.

How it compares

Compared to other midsize trucks, the 2022 Gladiator EcoDiesel occupies a unique position. The standard 3.6L V6 Gladiator 4×4 typically achieves around 19 MPG combined, making the diesel a noticeable improvement. A Toyota Tacoma 4×4 with the V6 engine lands around 20 MPG combined. A comparable Ford Ranger 4×4 EcoBoost achieves roughly 22 MPG combined. The Chevrolet Colorado Duramax diesel nets around 23 MPG combined. These figures illustrate the trade-offs buyers make. The Gladiator EcoDiesel isn’t the thriftiest option in the segment; it prioritizes torque, capability, and a distinct Jeep experience, aspects that resonate deeply with its loyal following.

Tips to maximize efficiency

One simple way to improve fuel economy is to maintain consistent speeds, especially on the highway. Avoid aggressive acceleration and braking, as these habits significantly reduce efficiency. The Gladiator’s diesel engine delivers ample torque at low RPMs, allowing for relaxed cruising and reduced fuel consumption.

Proper tire inflation is critical for optimizing fuel economy. Check your tire pressure regularly and ensure it matches the manufacturer’s recommendation, typically found on the doorjamb. Underinflated tires create more rolling resistance, requiring the engine to work harder and consume more fuel. Consider upgrading to low rolling resistance tires when it’s time for replacement.

Minimize unnecessary weight. The more weight the Gladiator carries, the lower its fuel economy will be. Remove any unnecessary items from the bed and passenger compartment. Also, consider the aerodynamic impact of any aftermarket accessories, such as roof racks or oversized tires. GLADIATOR MPG across all years can be affected by such changes.

Regular maintenance is essential for optimal engine performance and fuel efficiency. Follow the manufacturer’s recommended maintenance schedule, including oil changes, air filter replacements, and fuel filter replacements. A well-maintained engine runs more efficiently and consumes less fuel.
