Can You Get A Diesel Jeep Gladiator
The Jeep Gladiator has attracted many fans since its debut. People love its rugged style and the freedom it offers for both city driving and off-road adventures.
But one question comes up often: Can you get a diesel-powered Jeep Gladiator? Many drivers want the extra torque, efficiency, and towing power that a diesel engine provides.
If you’re thinking about buying a Gladiator or just curious about your options, this article breaks down everything you need to know.

Diesel Jeep Gladiator: Is It Available?
Yes, you can get a diesel Jeep Gladiator—but with some important details to consider. Jeep introduced the 3.0L EcoDiesel V6 option for the Gladiator in the 2021 model year. This engine quickly became popular among those who needed more pulling power and better fuel economy than the standard gas V6.
However, in 2023, Jeep announced that it would discontinue the EcoDiesel option for the Gladiator after the 2023 model year. This means you can find new or used diesel Gladiators from 2021 to 2023, but after that, only gasoline engines are available from the factory.
Diesel Vs Gasoline Gladiator: Key Differences
Choosing between diesel and gasoline engines isn’t just about power. Let’s compare the main differences that matter for most buyers.
| Feature | Diesel Gladiator | Gasoline Gladiator |
|---|---|---|
| Engine | 3.0L EcoDiesel V6 | 3.6L Pentastar V6 |
| Horsepower | 260 hp | 285 hp |
| Torque | 442 lb-ft | 260 lb-ft |
| Towing Capacity | 6,500 lbs | 7,650 lbs |
| Fuel Economy (Combined) | 24 mpg | 19 mpg |
| Availability | 2021–2023 | 2020–present |
Key insights:
- The diesel engine offers much more torque, which is great for off-roading and towing.
- The gasoline engine has a slightly higher towing capacity due to its lighter weight.
- Fuel economy is better with diesel, especially for highway driving or carrying heavy loads.

Why Choose A Diesel Jeep Gladiator?
Some drivers benefit more from a diesel engine. Here’s when diesel makes the most sense:
- Long-distance drivers: Diesel engines are more efficient on highways.
- Towing and hauling: The extra torque makes it easier to pull trailers, boats, or campers.
- Off-road adventures: Diesel power gives better control on steep or rough terrain.
- Fuel costs: Diesel can be more economical in some regions, though this depends on local prices.
But there are trade-offs. Diesel Gladiators are usually more expensive up front, and maintenance can cost more. Diesel engines also need DEF (Diesel Exhaust Fluid) refills, which is a small extra step for owners.
Diesel Engine Ownership: What To Expect
If you’re new to diesel vehicles, a few things are different compared to gasoline models.
| Aspect | Diesel Gladiator | Gasoline Gladiator |
|---|---|---|
| Engine Noise | Louder at idle, smoother at speed | Quieter overall |
| Maintenance | Oil changes less often but higher cost | Cheaper, more frequent oil changes |
| Fuel Availability | Diesel stations needed | Gasoline widely available |
| Resale Value | Often higher if well maintained | Steady, easier to sell |
Non-obvious insight: Diesel engines can last longer than gasoline ones, sometimes reaching 300,000 miles or more with good care. Many buyers miss that modern diesel engines need clean, high-quality fuel and regular DEF refills for emissions.

Finding A Diesel Jeep Gladiator: What To Look For
Since new diesel Gladiators are no longer produced, your best bet is a used model from 2021–2023. Here’s what to check before buying:
- Service history: Regular oil changes and DEF system maintenance are crucial.
- Emissions recalls: Ask if the vehicle had any emissions system recalls or updates.
- Previous use: Trucks used for heavy towing may have more wear on transmission and brakes.
- Aftermarket modifications: Some owners add performance parts. Make sure any mods are legal and don’t void the warranty.
A certified pre-owned (CPO) Gladiator from a Jeep dealer can offer extra peace of mind, as these usually pass strict inspections.
Should You Buy A Diesel Gladiator Now?
If you value fuel economy, torque, and plan to keep your truck for many years, a diesel Gladiator is a smart choice. However, if you want the latest models or plan to resell soon, the limited production years may make diesel less appealing.
Prices for used diesel Gladiators hold strong, but you may pay a premium. Be ready for slightly higher maintenance costs and the need to find diesel fuel on road trips.
Alternatives To The Diesel Jeep Gladiator
With The Diesel Engine Gone, What Else Can You Consider?
- Gasoline Gladiator: Still a great choice, with strong resale value and easier maintenance.
- Toyota Tacoma Diesel (not in US): Popular in other countries, but not available here.
- Ford Ranger and Chevrolet Colorado: Offer strong gas engines and, in some markets, diesel options.
- Upcoming hybrid trucks: Some brands are moving toward hybrid or electric power for better efficiency.
For most US buyers, the gasoline Gladiator is now the main option, but the used diesel market is worth exploring if you want the benefits diesel provides.
