You can also explore related research, ownership cost insights, and model comparisons across our site to make a confident decision. Whether you commute in the city or spend more miles on the highway, the right used car can lower fuel costs and reduce maintenance stress while keeping you moving with confidence.

Why fuel economy matters in a used car

Choosing a used car with strong fuel economy can deliver year round savings and long term value. Good MPG reduces fuel spend, lowers emissions, and often aligns with vehicles that are easier to live with on daily commutes. Efficient models also tend to hold demand in the used market, which can help future resale value. Beyond the pump, many efficiency focused trims include modern transmissions, lighter components, and aerodynamic design that make highway cruising quieter and smoother.

What counts as good gas mileage

Good MPG depends on vehicle type and driving mix. As a quick guide, many shoppers consider 30 or higher combined MPG strong for compact cars, 28 to 33 combined MPG good for midsize sedans, and 28 or higher combined MPG solid for small SUVs. Hybrids commonly deliver 40 to 55 combined MPG or more, and select plug in hybrids offer all electric miles for daily trips. EPA estimates vary by model year and trim, and real world results can differ based on load, terrain, weather, and driving habits.

How to evaluate real world MPG before you buy

EPA fuel economy labels are a good starting point, but local driving and maintenance history play a role. Review the window label if available, research on fueleconomy dot gov, and compare owner reported averages from reputable sources. During a test drive, check the trip computer average, confirm tire pressure, and reset the meter to see short route performance. Ask for service records that show consistent oil changes and air filter replacements, and inspect tires for type and tread life since aggressive or oversized tires can reduce MPG.

Use checklists like used-car-buying-checklist and inspection help at used-car-inspection-checklist for a thorough review.

Features that improve MPG on used cars

Certain technologies boost efficiency without changing how you drive. Look for these when comparing trims and years:

Maintenance and driving tips to maximize MPG

Small habits add up to large savings. A well maintained car with mindful driving can outperform its label rating in many conditions.

Budget and value considerations

Fuel savings accumulate over time, so compare MPG alongside price, expected maintenance, insurance, and depreciation. A hybrid with higher purchase price may still be the better value if it saves enough fuel and holds demand in the used market. Review reliability trends and resale strength before deciding.
