The Dodge Durango fuel type depends on the engine: the V6 runs on 87-octane regular unleaded, the 5.7L HEMI recommends 89-octane, while SRT and Hellcat models require premium 91+ octane gasoline for peak performance.
In this guide, we break down the fuel requirements for every Dodge Durango engine and trim, while also addressing common questions about fuel efficiency, tank size, and the use of premium gas.
What Fuel Does Dodge Durango Use?
The Dodge Durango runs on unleaded gasoline, but the octane rating depends on the engine.
- Standard V6 models use regular unleaded (87 octane).
- The 5.7L HEMI V8 is recommended to run on 89 octane mid-grade.
- Performance models like the SRT and Hellcat require 91+ octane premium gasoline.
In short, your engine size determines the type of fuel. Let’s explore each one in detail.
Dodge Durango Fuel Types by Engine
The Dodge Durango offers several engine options, each with different fuel requirements. Here’s a complete breakdown:
A. 3.6L Pentastar V6
The most common engine in the Durango lineup, the 3.6L Pentastar V6, is designed for daily driving and efficiency. It performs perfectly with 87-octane regular gasoline. Using higher octane fuel does not improve performance or mileage in this engine; therefore, regular gasoline is the most cost-effective choice.
B. 5.7L HEMI V8
The legendary 5.7L HEMI V8 delivers strong towing power and performance. Dodge recommends 89-octane mid-grade fuel for this engine. While it can run on 87 octane, long-term use of lower-grade gas may slightly reduce performance and efficiency. For best results, stick with 89.
C. 6.4L SRT HEMI V8
The 6.4L SRT HEMI is a performance powerhouse. It requires premium gasoline (91 octane or higher) to achieve maximum horsepower and prevent engine knock. Owners should avoid using lower-grade fuels, as they may cause noticeable performance loss.
D. 6.2L Supercharged HEMI V8 (Hellcat)
The Hellcat-powered Durango is one of the most powerful SUVs ever built. This supercharged 6.2L V8 absolutely requires premium 91–93 octane gasoline. Using regular fuel in this engine is not recommended, as it could lead to knocking, reduced performance, and possible engine damage.
Quick Reference Table
| Engine Type | Recommended Fuel | Octane Rating | Notes |
| 3.6L V6 | Regular Gasoline | 87 | Cost-efficient and reliable |
| 5.7L V8 | Mid-Grade Gasoline | 89 | Improves towing & performance |
| 6.4L SRT V8 | Premium Gasoline | 91+ | Required for peak output |
| 6.2L Hellcat | Premium Gasoline | 91–93 | Mandatory for supercharged power |
Dodge Durango Fuel Requirements by Trim
Each trim level is tied to a specific engine, so the fuel type also varies by trim.
- SXT, GT, Citadel → 3.6L V6 → Regular unleaded (87).
- R/T → 5.7L V8 → Mid-grade (89 recommended).
- SRT 392 → 6.4L V8 → Premium (91+).
- SRT Hellcat → 6.2L V8 → Premium (91–93).
This breakdown makes it easy for owners to know what fuel their specific trim needs.

Recommended Octane Ratings Explained (87 vs 89 vs 91+)
Octane ratings measure a fuel’s resistance to knocking or pinging during combustion.
- 87 (Regular): Perfectly fine for most daily drivers like the Durango V6.
- 89 (Mid-Grade): Gives HEMI engines smoother performance, especially under load.
- 91–93 (Premium): Required for high-performance engines like the SRT and Hellcat to prevent knocking and ensure maximum power output.
Does Using Premium Fuel Improve Performance?
For V6 and 5.7L HEMI engines, using premium fuel will not significantly improve performance or efficiency beyond the manufacturer’s recommendations.
However, for the SRT 392 and Hellcat trims, a premium is required. Skipping premium in these trims can cause loss of power, poor fuel economy, and even engine issues.
Fuel Tank Capacity by Model Year & Trim
Fuel tank size determines how far you can go between fill-ups.
| Model Years | Fuel Tank Capacity | Average Range (MPG) |
| 2020–2023 | 24.6 gallons | 400–500 miles |
| 2011–2019 | 24.6 gallons | 380–480 miles |
| 2000–2010 | 27 gallons | 360–450 miles |
Most modern Durangos come with a 24.6-gallon tank, offering decent driving range for both city and highway use.
Dodge Durango Gas Mileage & Efficiency
Gas mileage varies depending on engine choice:
- V6: 19 MPG city / 26 MPG highway.
- 5.7L HEMI V8: Approximately 14–22 MPG, depending on driving conditions.
- 6.4L SRT V8: Around 13–19 MPG.
- Hellcat 6.2L V8: 12–17 MPG.
Clearly, higher-performance engines sacrifice fuel efficiency for raw power.
Can the Dodge Durango Run on E85 or Flex-Fuel?
Most Dodge Durango models are not flex-fuel capable. While some earlier V6 versions could use E85, the majority of modern Durangos are designed strictly for gasoline. Always check your owner’s manual before using alternative fuels.
