Fuel economy by configuration
EPA estimates from the era show a noticeable difference between automatic and manual transmissions.
- Automatic transmission (4-speed): EPA estimates about 29–31 mpg city and 37–38 mpg highway, for a combined around 32–33 mpg.
- Manual transmission (5-speed): EPA estimates about 33–34 mpg city and 40–42 mpg highway, for a combined around 37–38 mpg.
In everyday driving, most owners see mileage in the low to mid-30s mpg with automatics and mid-to-upper 30s mpg with manuals, depending on traffic and terrain.
What can affect the mileage you actually see
Several factors can swing your real-world mpg well above or below the EPA estimates.
- Tire condition and inflation: Under-inflated tires dramatically reduce efficiency.
- Engine and transmission condition: Regular oil changes, air filter replacements, and proper maintenance help.
- Driving style: Aggressive acceleration and high speeds reduce mpg; steady speeds improve it.
- Vehicle load and accessories: Extra weight and roof racks increase drag and reduce mileage.
- Maintenance and fuel quality: Using the recommended grade of fuel and keeping the car tuned up aids efficiency.
Keeping these factors in check can help you reach or approach the EPA estimates for your Aveo.
