Dodge Journey 3.6 V6 Fuel Consumption: Real-World Figures & What to Expect
The Dodge Journey 3.6 V6 is known more for space and performance than for economy, but its fuel consumption is still a key consideration for buyers and owners. Below is a fact-based look at its fuel use using only verified data from credible sources.
Engine & Model Overview
The 3.6‑litre V6 in the Dodge Journey is Chrysler’s well‑known Pentastar engine. In many markets, including South Africa, this is the most powerful engine offered in the Journey range and is typically paired with a 6‑speed automatic transmission.
Stellantis (formerly Fiat‑Chrysler) notes that the 3.6‑litre Pentastar V6 is widely used across Dodge, Chrysler, Jeep and Ram vehicles, emphasising a balance of power and reasonable efficiency for a naturally aspirated V6 engine
(see general Pentastar V6 information on Stellantis’ media site:
https://media.stellantisnorthamerica.com/newsrelease.do?id=10449).
Official Fuel Consumption Figures
Official fuel consumption values vary slightly by market and test cycle (e.g. U.S. EPA vs. European NEDC vs. later WLTP). For the Dodge Journey with the 3.6 V6, the clearest published figures come from the U.S. EPA and manufacturer‑aligned data.
U.S. EPA Ratings (3.6 V6, Automatic, Petrol)
The U.S. Department of Energy and EPA list fuel economy for the 2019 Dodge Journey with the 3.6‑litre V6 and 6‑speed automatic as follows:
- 19 miles per gallon (mpg) combined
- 17 mpg city
- 25 mpg highway

These figures apply to the U.S. test cycle and typically represent a front‑wheel‑drive configuration. AWD models, where available, generally use slightly more fuel.
Converting EPA Ratings to L/100 km
To relate this to the way fuel consumption is usually expressed in South Africa (litres per 100 km), we can convert the EPA combined figure:
- 1 mpg ≈ 235.21 / (L/100 km)
- So 19 mpg combined ≈ 12.4 L/100 km
Similarly:
- 17 mpg city ≈ 13.8 L/100 km
- 25 mpg highway ≈ 9.4 L/100 km
These are approximate conversions based on the EPA values above. The original EPA data can be checked at

Typical Real‑World Consumption Range
Real‑world fuel consumption can differ from official figures due to driving style, traffic, load, climate, and fuel quality. Owner‑reported figures for the Dodge Journey 3.6 V6 often cluster around the EPA combined number, with some variance.
For context, U.S. government guidance on real‑world fuel economy notes that actual consumption can differ significantly from label values depending on how and where the vehicle is driven
(see EPA’s explanation of fuel economy variability:
https://www.fueleconomy.gov/feg/factors.shtml).
In practice, many drivers can expect:
- Around 12–14 L/100 km in mixed driving (close to the 19 mpg combined EPA figure).
- Higher figures in heavy city traffic or with aggressive acceleration.
- Lower figures on steady, long‑distance highway journeys driven at moderate speeds.
These expectations are grounded in the EPA’s combined rating and its guidance that real‑world results may vary, rather than in speculative claims.
Factors That Affect Dodge Journey 3.6 V6 Fuel Consumption
The same factors that influence any vehicle’s fuel use apply to the Journey 3.6 V6. The U.S. Department of Energy provides tested, quantified guidance on how driving and maintenance choices affect fuel consumption and economy:
- Driving speed: FuelEconomy.gov notes that fuel economy typically decreases rapidly at speeds above 50 mph (about 80 km/h)
https://www.fueleconomy.gov/feg/driveHabits.jsp. - Aggressive driving: Rapid acceleration and hard braking can lower fuel economy by up to 15–30% at highway speeds and 10–40% in stop‑and‑go traffic
https://www.fueleconomy.gov/feg/driveHabits.jsp. - Tyre pressure: Under‑inflated tyres can lower fuel economy by around 0.2% for every 1 psi drop in pressure averaged across all tyres
https://www.fueleconomy.gov/feg/maintain.jsp. - Vehicle load and roof racks: Extra weight, and especially roof‑mounted cargo, increases aerodynamic drag and fuel consumption
https://www.fueleconomy.gov/feg/cargocauses.shtml.
Because the Dodge Journey 3.6 V6 is a relatively heavy, multi‑purpose vehicle, these factors can have an especially noticeable impact on fuel use.
Fuel Type and Engine Efficiency
The 3.6‑litre Pentastar V6 in the Journey is a petrol engine designed for regular unleaded fuel in most markets. Chrysler’s technical overview of the Pentastar family highlights its use of variable valve timing and other efficiency‑oriented features compared with older V6 designs
https://media.stellantisnorthamerica.com/newsrelease.do?id=10449.
These technologies help the engine deliver strong performance for a large family vehicle while keeping fuel consumption in line with other naturally aspirated V6 engines of similar power and weight class. However, it will almost always use more fuel than smaller turbocharged four‑cylinder engines, especially in urban driving.
City vs Highway Consumption
The gap between city and highway figures for the Dodge Journey 3.6 V6 is relatively large, reflecting the impact of stop‑start driving and acceleration on a heavier vehicle with a sizeable V6 engine.
Based on the EPA data for the 2019 3.6 V6 automatic model:
- City: 17 mpg (≈13.8 L/100 km)
- Highway: 25 mpg (≈9.4 L/100 km)
https://www.fueleconomy.gov/feg/bymodel/2019_Dodge_Journey.shtml
In practical terms, this means that owners who mostly drive in dense, stop‑start traffic are likely to see fuel consumption substantially higher than those doing longer highway commutes at steady speeds.
How the Dodge Journey 3.6 V6 Compares
While direct, model‑year‑identical comparisons depend on a variety of factors, the EPA’s database shows that midsize to large three‑row crossovers with V6 petrol engines typically fall into a similar combined fuel economy band (often 18–21 mpg combined)
You can compare various vehicles directly at:
https://www.fueleconomy.gov/feg/findacar.shtml.
This places the Dodge Journey 3.6 V6 broadly in the expected range for a three‑row, V6‑powered family vehicle rather than as an outlier in either direction.
Improving Your Dodge Journey 3.6 V6 Fuel Consumption
While you cannot change the fundamental engine design, you can influence how much fuel your Journey uses day‑to‑day. The U.S. Department of Energy recommends several measures that apply to the Journey 3.6 V6 as well:
- Adopt smoother driving habits
Avoid rapid acceleration and hard braking. FuelEconomy.gov reports potential improvements of up to 10–40% in city conditions with gentler driving
https://www.fueleconomy.gov/feg/driveHabits.jsp. -
Observe near‑optimal speeds on the highway
Driving significantly above 80–90 km/h increases aerodynamic drag and fuel use. Keeping speeds moderate, where safe and legal, generally helps reduce consumption
https://www.fueleconomy.gov/feg/driveHabits.jsp. -
Maintain correct tyre pressures
Keeping tyres properly inflated improves fuel efficiency and safety. Under‑inflation increases rolling resistance and fuel consumption
https://www.fueleconomy.gov/feg/maintain.jsp. -
Reduce excess weight and drag
Remove unnecessary heavy items from the vehicle and take off roof racks or boxes when not in use, as they increase aerodynamic drag
https://www.fueleconomy.gov/feg/cargocauses.shtml. -
Keep up with scheduled servicing
Timely oil changes, air‑filter replacement and overall engine maintenance help the engine run at its designed efficiency. General maintenance tips are outlined here:

Summary: What to Expect from a Dodge Journey 3.6 V6
Based on verified EPA data and manufacturer‑aligned technical information, typical fuel consumption expectations for the Dodge Journey 3.6 V6 are:
- Around 19 mpg combined (≈12.4 L/100 km) on the U.S. test cycle
- Approximately 17 mpg city (≈13.8 L/100 km) and 25 mpg highway (≈9.4 L/100 km)

Real‑world figures will vary, but for most owners, a mixed driving average in the 12–14 L/100 km range is realistic, with higher consumption in heavy city traffic and lower numbers on open highways driven at steady speeds.
For South African drivers and buyers researching fuel consumption alongside local data, these official figures provide a solid benchmark for what to expect from the Dodge Journey 3.6 V6.
