In general, a 2014 Honda Civic can travel about 420–435 miles per full tank in most non-Si models with an automatic transmission, while the Civic Si typically yields around 330 miles per tank.
The exact range depends on the car's fuel tank capacity, the EPA-rated miles-per-gallon (MPG) for the trim and transmission, and driving conditions. This article provides typical estimates for common configurations and how to calculate your own range.
Fuel tank capacity and economy in the 2014 Civic
The 2014 Civic generally uses a 13.2-gallon fuel tank. EPA fuel-economy ratings vary by model and transmission, which in turn affects how far you can drive on a full tank.
The following estimates assume a 13.2-gallon fuel tank and EPA-rated combined miles per gallon for typical 2014 Civic configurations.
- Civic with CVT automatic (LX/EX/EX-L): about 33 mpg combined — roughly 435 miles per tank.
- Civic with a 6-speed manual transmission (some trims): about 31–32 mpg combined — roughly 410–422 miles per tank.
- Civic Si (2.4L, performance variant): about 25 mpg combined — roughly 330 miles per tank.
These figures are approximations. Real-world range varies with driving style, road conditions, climate, and fuel-quality variations by year and trim.
How to estimate your own range
To estimate your own range, multiply the tank capacity by the vehicle’s real-world MPG or the EPA rating for your exact trim. If you know your city and highway MPG, you can compute a weighted average based on your typical driving mix (for example, 55% highway and 45% city).
Example calculation
Using a 13.2-gallon tank and a combined MPG of 33 (typical for a non-Si CVT 2014 Civic): 13.2 × 33 ≈ 436 miles. For a Si with ~25 MPG combined: 13.2 × 25 ≈ 330 miles.
Summary
In practice, expect about 420–435 miles per tank for most 2014 Civics with an automatic transmission, around 410–422 miles for manual versions, and roughly 330 miles for the Civic Si. Your actual mileage will depend on your driving habits and conditions.
