Many car buyers dream about owning a Jeep Wrangler. Its rugged look, off-road skills, and strong reputation make it a favorite across the US and beyond.
But one question often comes up: Do Jeep Wranglers take diesel? If you are thinking about buying or already own a Wrangler, understanding its engine options is important.
Diesel engines can offer better fuel economy and more torque, but not every Wrangler model has this choice. Let’s explore which Wranglers use diesel, their pros and cons, and what to consider if you want a diesel-powered Jeep.
Gas Vs Diesel: What Does A Jeep Wrangler Use?
Most Jeep Wranglers on the road today use gasoline engines. The classic 3.6L Pentastar V6 is the most common, found in many models since 2012. Jeep also offers a 2.0L turbocharged four-cylinder, and recently, a powerful 6.4L V8 in the Rubicon 392. These engines are reliable and easy to fuel up anywhere.
However, Jeep did introduce a diesel option for the Wrangler in 2020. The 3.0L EcoDiesel V6 became available on select trims, giving buyers a new choice.
| Engine Type | Model Years | Fuel Type | Availability |
|---|---|---|---|
| 3.6L V6 | 2012–present | Gasoline | All trims |
| 2.0L Turbo | 2018–present | Gasoline | Most trims |
| 3.0L EcoDiesel V6 | 2020–2023 | Diesel | Unlimited, Rubicon, Sahara |
So, not all Jeep Wranglers take diesel. Only a few newer models have the diesel engine option.
Which Jeep Wrangler Models Take Diesel?
The EcoDiesel engine is available on the four-door Wrangler Unlimited models, usually in the Rubicon, Sahara, and Sport trims. Two-door Wranglers do not offer diesel.
Jeep released the EcoDiesel for the 2020, 2021, 2022, and 2023 model years. In 2024, Jeep stopped offering the diesel engine for the Wrangler. So, if you want a diesel Wrangler, you need to look for a used model from these years.
| Model Year | Diesel Availability |
|---|---|
| 2020 | Yes |
| 2021 | Yes |
| 2022 | Yes |
| 2023 | Yes |
| 2024 | No |
If you see a Jeep Wrangler with a diesel badge or EcoDiesel logo, it’s likely from one of these years.
Why Choose Diesel For A Jeep Wrangler?
Diesel engines are popular for several reasons. Here’s why some buyers prefer a diesel-powered Wrangler:
- Better fuel economy: The EcoDiesel Wrangler gets about 25 mpg combined, compared to 20 mpg for the gas V6.
- Higher torque: Diesels produce more low-end torque, which helps in off-road driving and towing.
- Longer range: With a larger fuel tank and better efficiency, you can drive farther between fill-ups.
- Durability: Diesel engines can last longer if cared for well.
But there are also downsides:
- Higher cost: Diesel Wranglers are usually more expensive than gas models.
- Maintenance: Diesel engines require special care, like using diesel exhaust fluid (DEF).
- Limited availability: Few dealerships have diesel Wranglers in stock.
Here’s a quick comparison of the EcoDiesel vs. Gas V6:
| Feature | EcoDiesel | Gas V6 |
|---|---|---|
| Horsepower | 260 hp | 285 hp |
| Torque | 442 lb-ft | 260 lb-ft |
| Fuel Economy (Combined) | 25 mpg | 20 mpg |
| Towing Capacity | 3,500 lbs | 3,500 lbs |
One non-obvious insight: The EcoDiesel is not allowed in some states with strict emissions rules, like California. Always check local laws before buying.
What Happens If You Use The Wrong Fuel?
It’s important to know your Wrangler’s engine type. Putting diesel in a gas engine (or gasoline in a diesel engine) can cause major damage.
- Diesel in gas engine: Won’t run, may damage fuel system.
- Gasoline in diesel engine: Can ruin injectors, pumps, and even the engine itself.
If you are unsure, check your owner’s manual or the fuel cap. The fuel cap will say “Diesel Fuel Only” if it’s a diesel Jeep.
Common Mistakes When Buying A Diesel Wrangler
- Assuming all Wranglers have diesel engines: Only select models from 2020–2023 offer diesel.
- Ignoring emissions rules: Some states restrict diesel vehicles.
- Not budgeting for maintenance: Diesel engines cost more to maintain.
- Overlooking DEF requirements: EcoDiesel Wranglers need diesel exhaust fluid, which is an extra cost.
- Buying for short trips: Diesels perform best on longer drives. Short trips can cause engine problems.
Practical Tips For Diesel Wrangler Owners
- Use high-quality diesel fuel from trusted stations.
- Check DEF fluid regularly.
- Warm up the engine before heavy driving.
- Follow the maintenance schedule in your manual.
- If you plan to resell, remember diesel models may have lower demand after 2024.
