Is a 2004 Honda Civic good on gas?

Yes. For its age, the 2004 Honda Civic is generally quite fuel-efficient, with gasoline-only models typically delivering roughly 32–34 mpg combined (varies by trim and transmission), and the Civic Hybrid often achieving mid-40s to around 50 mpg in mixed driving.


The 2004 Civic line offered several trims and configurations, so actual fuel economy depends on factors like engine type, transmission, and the car’s condition. Below is a breakdown of typical figures and practical guidance for maximizing efficiency.


Fuel economy by model and drivetrain


The figures below reflect typical ranges for common 2004 Civic configurations. Real-world results depend on maintenance, tires, driving style, and climate.



  • Gasoline-only trims (DX/LX/EX) with the 1.7L engine: roughly 32–34 mpg combined, with manuals usually a touch higher and automatics a touch lower.

  • 2004 Civic Si (performance model with a 2.0L engine): typically in the mid-20s mpg combined, lower than non-Si trims due to sportier tuning and higher-load driving.

  • 2004 Civic Hybrid: commonly in the mid-40s to about 50 mpg combined, depending on driving conditions and battery health.


In practice, you’ll see the best efficiency from the manual gasoline trims at steady highway speeds, while the hybrid offers a noticeable advantage in city and stop-and-go driving. Always consider the car’s maintenance history when evaluating MPG expectations.


Maximizing fuel economy in a 2004 Civic


To help you extract the most miles per gallon from a 2004 Civic, consider the following practical steps and habits. The list below outlines targeted actions that can influence efficiency.



  • Keep tires inflated to the manufacturer’s recommended pressures to minimize rolling resistance.

  • Use the appropriate grade of motor oil and follow service intervals; clean oil reduces engine effort and can help efficiency.

  • Replace the air filter and oxygen sensors as needed; a clogged filter or failing sensor can reduce mpg.

  • Lighten the load and remove roof racks when not in use to cut wind resistance and weight.

  • Avoid aggressive acceleration and frequent rapid braking; smooth, steady driving improves fuel economy.

  • Use cruise control on highways when appropriate to maintain steady speeds and optimize efficiency.

  • Keep routine maintenance up to date (spark plugs, ignition system, cooling system) to prevent drivability issues that can hurt mpg.


These practices can help you maintain or improve fuel efficiency, even as the car ages. Real-world results will vary, but consistent maintenance and mindful driving typically yield positive effects on a 2004 Civic’s gas mileage.


Is it worth buying a 2004 Civic today?


For budget-conscious buyers, a well-maintained 2004 Civic can still offer reliable transportation with good fuel economy relative to many older compact cars. Important considerations include the car’s maintenance history, the condition of the engine and transmission, and any rust or wear common to older vehicles. If you’re shopping used, obtain a thorough inspection, review maintenance records, and consider the potential costs of parts replacement (timing belt, water pump, hoses, brakes) as the car ages.


Summary


The 2004 Honda Civic remains a solid, fuel-efficient option among older compact cars. Gasoline models typically deliver in the low-to-mid 30s mpg combined, while the Civic Hybrid can push into the mid-40s to around 50 mpg in mixed driving. Real-world mileage depends on trim, transmission, and upkeep. With attentive maintenance and mindful driving habits, a well-kept 2004 Civic can continue to deliver reliable economy-at-scale relative to its age, making it a reasonable choice for budget-minded buyers or those seeking a used, efficient daily driver.

Are Honda Civics cheap on gas?


Summary: The Honda Civic is fuel-efficient for its class, especially in 1.5L turbo and hybrid forms; expect mid-30s mpg combined for typical non-hybrid trims and significantly higher for hybrid versions, with real-world results varying by use and maintenance.



Is the Honda Civic good on gas?


Yes, the Honda Civic is generally considered a fuel-efficient car, with the latest models achieving up to an EPA-estimated 32 city/41 highway/36 combined MPG for the standard LX trim, and even higher ratings for the hybrid version. The hybrid model offers exceptional efficiency, with some versions getting 50 city/47 highway/49 combined MPG. 
Here are the specific fuel efficiency ratings for recent models:

  • 2025 Honda Civic Sedan:
    • LX: 32 city / 41 highway / 36 combined MPG 
    • Sport: 31 city / 39 highway / 34 combined MPG 
  • 2025 Honda Civic Hybrid:
    • Sport Hybrid and Sport Touring Hybrid: 50 city / 47 highway / 49 combined MPG 
  • 2024 Honda Civic Sedan:
    • LX: 31 city / 40 highway / 35 combined MPG 
    • EX: 33 city / 42 highway / 36 combined MPG 

Factors that influence mileage:
  • Driving conditions: Your actual mileage will vary depending on your driving habits, maintenance, and the conditions of the road. 
  • Engine type: The specific engine and transmission (CVT or manual) in your trim level will affect fuel economy. 
  • Hybrid vs. Gas: The hybrid version provides significantly better fuel efficiency, especially in city driving.
