Dodge Durango Gas Mileage: Real-World Fuel Costs Explained

The Dodge Durango is a three-row SUV designed for drivers who want a combination of passenger space, towing capability, everyday comfort, and powerful engine options. However, its size and performance come with an important ownership consideration: fuel consumption.

If you are considering buying a Dodge Durango or already own one, understanding its gas mileage can help you estimate monthly expenses, plan long-distance trips, and decide which engine best suits your driving habits.

Dodge Durango gas mileage varies significantly by engine, drivetrain, model year, and driving conditions. Recent models equipped with the 3.6-liter V6 can achieve approximately 20 MPG combined, while V8-powered versions typically deliver lower fuel economy. High-performance SRT Hellcat models can average just 13 MPG combined according to EPA estimates.

The actual cost of operating a Durango depends on more than its official MPG rating. Gasoline prices, city traffic, highway speeds, towing, tire pressure, and driving style all influence how much money you spend at the pump.

This guide explains Dodge Durango fuel economy, compares popular engine options, calculates realistic gasoline expenses, and shares practical ways to reduce fuel costs.

Dodge Durango MPG: Official Fuel Economy Ratings

The U.S. Environmental Protection Agency (EPA) provides estimated fuel economy ratings that help drivers compare vehicles under standardized testing conditions. These estimates are useful starting points, although individual results may differ.

For the 2026 Dodge Durango lineup, published ratings vary by configuration. Representative figures include the following. See 2026 Dodge Durango.

Dodge Durango engine	City MPG	Highway MPG	Combined MPG
3.6L V6, RWD	18	25	20
3.6L V6, AWD	17	24	20
5.7L HEMI V8, AWD	14	21	16
6.2L Supercharged V8, SRT Hellcat	12	17	13
6.4L V8, R/T 392	13	19	15

Note: Ratings are representative of listed 2026 configurations and may vary by trim and equipment. Always verify the exact model year, engine, and drivetrain before purchasing.

The figures reveal a clear pattern: the V6 generally offers the best fuel economy, while larger and higher-performance V8 engines consume more gasoline.

For drivers who spend most of their time commuting, the difference can translate into hundreds or even thousands of dollars over several years.

Real-World Dodge Durango Fuel Economy: What Should You Expect?

Official fuel economy ratings do not guarantee the mileage you will achieve during everyday driving.

A Dodge Durango driven primarily on congested city streets may deliver substantially lower MPG than one traveling on relatively flat highways at moderate speeds.

Real-world fuel economy depends on several factors:

Traffic conditions: Frequent stops and acceleration increase fuel consumption.
Driving speed: Sustained high speeds increase aerodynamic drag and can reduce MPG.
Vehicle load: Passengers, luggage, and towing equipment add weight.
Weather: Cold starts, extreme temperatures, and air-conditioning use can affect efficiency.
Maintenance: Incorrect tire pressure, neglected engine maintenance, and certain mechanical problems can reduce mileage.
Driving habits: Rapid acceleration and hard braking generally increase fuel use.

For planning purposes, owners can use the EPA combined rating as a baseline, then compare it with their own fuel records.

For example, a V6 Durango rated at 20 MPG combined may deliver less than 20 MPG in heavy urban traffic. A highway-focused driver may achieve better results under favorable conditions.

It is important not to treat an illustrative real-world estimate as a verified owner average. The most reliable way to determine your vehicle's actual fuel economy is to calculate it using miles driven and gallons consumed.

Dodge Durango V6 vs. V8: Which Engine Saves More Gas?

Engine selection is one of the biggest factors affecting Dodge Durango fuel costs.

1. Dodge Durango 3.6L Pentastar V6

The 3.6-liter Pentastar V6 is generally the most fuel-efficient option in the modern Durango lineup.

With representative EPA ratings of approximately 20 MPG combined, it can be a practical choice for families, commuters, and drivers who need a spacious SUV without prioritizing maximum engine output.

The V6 is particularly attractive for people who spend substantial time driving around town or taking family road trips.

Best for: Everyday driving, family transportation, and buyers prioritizing fuel economy.

2. Dodge Durango 5.7L HEMI V8

The 5.7-liter HEMI V8 offers greater power and a different driving experience, but its fuel economy is lower.

Representative ratings for an AWD configuration are approximately 14 MPG in the city, 21 MPG on the highway, and 16 MPG combined.

Drivers who value V8 performance should account for the additional gasoline expense when budgeting for ownership.

Best for: Drivers who prioritize V8 power and want a balance of performance and SUV utility.

3. Dodge Durango 6.4L V8

The 6.4-liter V8 is designed for higher performance. Its representative fuel economy rating is approximately 15 MPG combined.

For owners who enjoy stronger acceleration and performance-oriented driving, fuel economy may be a secondary consideration. Nevertheless, frequent city driving can make gasoline expenses particularly noticeable.

Best for: Performance enthusiasts who accept higher operating costs.

4. Dodge Durango SRT Hellcat 6.2L Supercharged V8

The SRT Hellcat is the least fuel-efficient option among these examples, with an EPA rating of approximately 13 MPG combined.

Its supercharged V8 delivers exceptional performance, but owners should expect to purchase gasoline more frequently than they would with the V6.

Best for: Buyers seeking high-performance capability rather than low fuel costs.

How Much Does It Cost to Fill Up a Dodge Durango?

The cost of filling up a Dodge Durango depends on the fuel tank capacity and the price per gallon at your local gas station.

Many recent Durango configurations have a fuel tank capacity of approximately 24.6 gallons. Actual capacity and usable fuel may vary by model year and configuration.

The calculation is straightforward:

Fuel tank capacity × price per gallon = estimated full-tank cost

For example, if gasoline costs $3.50 per gallon:

24.6 gallons × $3.50 = $86.10

At $4.00 per gallon, the same amount of gasoline would cost $98.40.

These are illustrative calculations, not current national gas-price quotes. Your actual cost will depend on local prices and how much fuel is needed to refill the tank.

Dodge Durango Gas Mileage: Monthly and Annual Fuel Costs

One of the easiest ways to understand fuel economy is to calculate how much gasoline you need for your typical driving distance.

The following example compares three representative Durango configurations using a hypothetical gasoline price of $3.50 per gallon and annual driving of 15,000 miles.

Engine	Combined MPG	Estimated monthly fuel cost	Estimated annual fuel cost
3.6L V6	20 MPG	$218.75	$2,625
5.7L HEMI V8	16 MPG	$273.44	$3,281.25
6.4L V8	15 MPG	$291.67	$3,500
6.2L SRT Hellcat	13 MPG	$336.54	$4,038.46

Calculations assume 15,000 miles per year, a constant price of $3.50 per gallon, and the stated combined MPG ratings. Actual costs will vary.

The V6 costs approximately $656 less per year in gasoline than the 5.7-liter V8 under these assumptions.

Compared with the SRT Hellcat, the estimated annual difference rises to approximately $1,413.

These figures illustrate why fuel economy should be considered when comparing engine options. They exclude insurance, maintenance, depreciation, financing, registration, and other ownership expenses.

How to Calculate Your Own Dodge Durango Fuel Costs

Use this formula:

Annual fuel cost = annual miles driven ÷ actual MPG × price per gallon

Suppose you drive 12,000 miles annually, average 18 MPG, and pay $3.60 per gallon.

12,000 ÷ 18 = 666.7 gallons per year.

666.7 × $3.60 = approximately $2,400 per year.

That equals approximately $200 per month.

To get a more accurate estimate, use your vehicle's actual MPG rather than relying exclusively on the manufacturer's or EPA's rating.

How Much Does It Cost to Drive a Dodge Durango 1,000 Miles?

A 1,000-mile trip provides another useful way to compare fuel expenses.

At an illustrative gasoline price of $3.50 per gallon, estimated costs would be:

Combined fuel economy	Gallons needed	Cost per 1,000 miles
20 MPG	50 gallons	$175.00
16 MPG	62.5 gallons	$218.75
15 MPG	66.7 gallons	$233.33
13 MPG	76.9 gallons	$269.23

For a long-distance trip, a more fuel-efficient Durango configuration could save money, particularly if you regularly travel thousands of miles each month.

However, highway conditions, driving speeds, weather, and cargo weight can change these estimates.

Does the Dodge Durango Get Good Gas Mileage?

Whether the Dodge Durango gets good gas mileage depends on your expectations and the type of vehicle you need.

Compared with smaller, lighter SUVs, the Durango's fuel economy is relatively modest. Its size, available V8 engines, and performance-oriented configurations help explain its higher fuel consumption.

However, buyers do not choose a three-row SUV solely for MPG. Passenger capacity, towing capability, interior space, and performance may be equally important.

The V6 is the logical starting point for shoppers who prioritize fuel savings. The V8 models make more sense for buyers who consider additional performance worth the higher gasoline expense.

When comparing vehicles, consider total ownership costs rather than fuel economy alone. A vehicle with better MPG is not automatically cheaper to own if its purchase price, insurance, financing, or maintenance costs are significantly higher.

How to Improve Dodge Durango Fuel Economy

Although the Durango is a relatively large SUV, everyday driving habits can help reduce unnecessary gasoline consumption.

1. Maintain Proper Tire Pressure

Underinflated tires increase rolling resistance and may reduce fuel efficiency. Check tire pressure regularly and follow the recommended cold-pressure specifications on the driver's door placard.

2. Accelerate Smoothly

Hard acceleration requires more fuel. Gradual acceleration and anticipating traffic conditions can help improve mileage, especially during city driving.

3. Avoid Excessive Highway Speeds

Higher speeds increase aerodynamic drag. Driving at a steady, moderate speed can help reduce fuel consumption on long trips.

4. Remove Unnecessary Weight

Heavy cargo that remains in the vehicle adds weight without providing a benefit. Remove unnecessary items before long drives.

5. Limit Unnecessary Idling

An idling engine consumes fuel without moving the vehicle. Avoid leaving the engine running unnecessarily while parked.

6. Keep Up With Maintenance

Follow the maintenance schedule for engine oil, air filters, spark plugs, and other components as applicable to your model. Address warning lights and unusual changes in fuel economy promptly.

7. Track Your Actual MPG

Record the odometer reading and gallons added at each fill-up. Over several tanks, this provides a more useful picture of your driving pattern than a single trip-computer reading.

These steps cannot transform a performance SUV into a fuel-efficient compact car, but they can help drivers avoid wasting fuel.

Is the Dodge Durango Expensive to Drive?

Fuel expenses are only one part of the total cost of owning a Dodge Durango.

The overall cost of ownership can include:

Gasoline and routine maintenance.
Tires and brake replacements.
Insurance premiums.
Registration and taxes.
Financing charges and depreciation.
Repairs outside the warranty period.

Performance models may also involve different tire, brake, and maintenance expenses than standard configurations.

Before purchasing a used Durango, review its service history, check for mechanical issues, and verify that the engine and drivetrain meet your needs.

If you drive long distances every year, fuel economy deserves particular attention because small MPG differences become more expensive as annual mileage increases.

Dodge Durango Gas Mileage: Is It Worth Buying?

The Dodge Durango can be a worthwhile choice for drivers who want a spacious SUV with substantial performance and towing capability. However, its gasoline consumption should be part of the buying decision.

The 3.6-liter V6 generally offers the most economical option among the configurations discussed here. The 5.7-liter HEMI V8 provides more power at a higher fuel cost, while the 6.4-liter and supercharged 6.2-liter V8 engines appeal to buyers who prioritize performance.

For buyers comparing used and new models, the best choice depends on the specific model year, drivetrain, purchase price, mileage, maintenance history, and expected annual driving distance.

A good buying strategy is to estimate fuel expenses using your own mileage and local gasoline prices before deciding which engine fits your budget.
