What is the gas mileage on a 2014 Dodge Avenger 2.4 L?
The officially estimated fuel economy for the 2014 Dodge Avenger with a 2.4-liter four-cylinder and front-wheel drive is about 21 miles per gallon in city driving, 30 mpg on the highway, and around 24 mpg combined.
This article examines those numbers, what they mean for daily driving, and how real-world results can vary, with tips to maximize efficiency and context on how the 2.4 L engine fits into the Avenger lineup from that model year.
EPA fuel economy ratings for the 2.4L Avenger
The EPA publishes standardized estimates for the 2.4L Avenger so buyers can compare figures across vehicles. The following figures reflect typical ratings for this engine in most trims when paired with the standard automatic transmission.
- 21 mpg in city driving
- 30 mpg on the highway
- 24 mpg combined
These figures are guidelines based on the EPA testing protocol. Real-world results can vary depending on driving conditions, maintenance, and equipment on the car.
Real-world factors and tips to maximize MPG
In practice, fuel economy on a 2014 Avenger can differ from the EPA estimates. The following factors most strongly influence what you’ll see at the pump.
- Driving style: Smooth acceleration, steady speeds, and minimal idling improve efficiency.
- Tire condition and inflation: Underinflated tires or worn tread increases rolling resistance and lowers MPG.
- Vehicle load and aerodynamics: Extra weight and roof racks can reduce efficiency, especially at highway speeds.
- Maintenance: Regular oil changes, clean air filters, and spark plug condition help keep the engine running efficiently.
- Climate control and environmental conditions: Air conditioning usage, cold starts, and outside temperatures can affect mpg.
To maximize fuel economy, consider adopting a steady cruising pace, ensuring tires are properly inflated to the recommended pressure, and performing routine maintenance on schedule.

Transmission and performance
The 2014 Dodge Avenger with the 2.4-liter four-cylinder engine was typically paired with a four-speed automatic transmission. This configuration delivers roughly 173 horsepower and 166 lb-ft of torque, with EPA fuel economy figures described above for standard front-wheel-drive setups.
The Avenger was discontinued after the 2014 model year in the U.S., so later model-year comparisons aren’t applicable for this specific engine and car. Used-car owners may see mileage results that reflect wear, maintenance history, and driving patterns.
How to verify mileage for your specific car
For any given 2014 Avenger with the 2.4L engine, the best indication of real-world mpg is your own driving data. Track miles driven and gallons used over multiple fill-ups to compute a reliable average, or use the vehicle’s onboard trip computer if available. This helps determine whether your car is meeting its EPA-rated performance or if maintenance issues are affecting efficiency.
Summary
In summary, the 2014 Dodge Avenger with a 2.4-liter engine and front-wheel drive is EPA-rated at about 21 mpg city, 30 mpg highway, and 24 mpg combined. Real-world mileage varies with driving style, maintenance, and vehicle load, but by following basic efficiency practices, owners can approach those estimates in daily use. This overview provides a practical reference for prospective buyers and current owners assessing fuel economy for this older sedan.
