When shopping for a used car, understanding MPG (miles per gallon) ratings is crucial for assessing fuel efficiency. MPG measures how far a car can travel on a single gallon of fuel, with higher numbers indicating better fuel economy.
For most drivers, a good MPG for a used car typically ranges between 25-35 MPG for combined city and highway driving.
However, the ideal rating can vary based on your driving habits and the type of vehicle you need. When evaluating MPG, consider both the official rating provided by the manufacturer and real-world performance from previous owners.
This helps ensure you’re choosing a vehicle that meets your fuel efficiency expectations, ultimately saving money at the pump. Read on to find out more.
How do you read MPG ratings?
They are usually broken down into city, highway, and combined MPG, indicating performance in different driving conditions:
What is MPG?
MPG stands for miles per gallon, a metric that indicates how far a vehicle can travel on one gallon of fuel and is usually presented in three categories: city, highway, and combined.
- City MPG: This rating reflects fuel efficiency during stop-and-go driving, typical in urban areas with frequent traffic lights and stop signs.
- Highway MPG: This measures fuel efficiency during steady-speed driving on highways, where there are fewer stops and starts.
- Combined MPG: This is an average of both city and highway MPG, offering a general idea of the car’s overall fuel efficiency.
MPG ratings are straightforward to read. For example, a vehicle with a city rating of 25 MPG, a highway rating of 35 MPG, and a combined rating of 30 MPG can travel 25 miles per gallon of fuel in the city, 35 miles per gallon on the highway, and an average of 30 miles per gallon in mixed driving conditions.
It’s essential to consider all three ratings, especially if your driving includes both city and highway routes. For instance, if you primarily drive in urban areas, the city MPG will be more relevant to you, while frequent highway drivers should pay closer attention to the highway MPG.
What constitutes a good MPG for a used car?
Determining what qualifies as a good MPG when it comes to used cars depends on various factors, including the type of vehicle and your driving needs. Generally, a combined MPG of 25-35 is considered good for most cars, particularly sedans and compact cars. For SUVs and trucks, which are typically less fuel-efficient due to their size and weight, a combined MPG of 20-25 might be considered acceptable.
Hybrids and electric vehicles (EVs) offer even higher MPG ratings, with some hybrid models exceeding 50 MPG. While these vehicles tend to be more expensive upfront, their superior fuel efficiency can lead to significant savings over time, especially if you drive frequently.

Factors that influence MPG ratings
Several factors can influence a vehicle’s MPG, both positively and negatively:
- Vehicle age and condition: Older vehicles may not perform as efficiently as they once did, particularly if they haven’t been well-maintained. Regular maintenance, such as oil changes and tire rotations, can help preserve fuel efficiency.
- Driving habits: Aggressive driving, such as rapid acceleration and braking, can significantly decrease MPG. Maintaining a steady speed and avoiding unnecessary idling can help maximize efficiency.
- Tire pressure: Underinflated tires create more rolling resistance, which can reduce MPG. Regularly checking and maintaining proper tire pressure can improve fuel economy.
- Weight: Carrying excess weight in your vehicle can reduce MPG. Removing unnecessary items from your car can help improve efficiency.
- Aerodynamics: Roof racks, spoilers, and other exterior modifications can affect a vehicle’s aerodynamics, reducing its efficiency. Keeping your car as streamlined as possible can help maintain good MPG.
Real-world MPG vs. manufacturer ratings
It’s important to note that manufacturer MPG ratings are often determined under controlled conditions and may not always reflect real-world driving. Factors like weather, terrain, and traffic can all impact a vehicle’s actual fuel efficiency. For this reason, it’s a good idea to research real-world MPG reports from previous owners or reputable automotive websites when assessing a used car.
Making an informed decision
When shopping for a used car, it’s crucial to consider MPG ratings alongside other factors like vehicle age, condition, and your driving habits. A car with a good rating can save you money on fuel and reduce your environmental impact, making it a smart investment in the long run. By understanding how to assess fuel efficiency, you can make a more informed decision and choose a used car that meets your needs without breaking the bank.
