2009 Civic is equipped with either a 5-speed manual transmission or a 5-speed automatic transmission. Its fuel consumption is as follows: 1. Automatic transmission model: The combined fuel consumption per 100 kilometers is approximately 8.7 liters. 2. Manual transmission model: The fuel consumption per 100 kilometers is about 7.9 liters. Relevant information about car fuel consumption is as follows: 1. Constant speed fuel consumption: This refers to the fuel economy indicator when the car is driving at a constant speed on a good road surface. Since constant speed driving is a basic operating condition for cars on highways, and this type of fuel consumption is easy to measure, it is widely adopted. 2. Road cycle fuel consumption: This is the fuel economy indicator measured when the car is driven in repeated cycles according to specified speed and time regulations on the road, also known as multi-condition road cycle fuel consumption. In the speed and time regulations, each cycle includes various driving conditions, and specifies the gear shifting time, braking and stopping time, as well as the values of driving speed, acceleration, and braking deceleration for each cycle.

I drove a 2009 Civic, and in terms of fuel consumption, my actual experience was around 10 liters per 100 kilometers in city driving, which could drop to about 8 liters on the highway. The car has a 1.8-liter engine, and during daily commutes with traffic congestion, it could go slightly higher, around 11 liters, but it becomes much more economical when driving in suburban areas. Driving habits really make a difference—if I accelerate gently and avoid sudden braking, a full tank of fuel can last dozens of kilometers longer. I make sure to change the engine oil and check the air filter every 5,000 kilometers, and maintain proper tire pressure, all of which help save on fuel costs. Fuel consumption tends to increase when going uphill or carrying heavy loads, so I recommend regular maintenance to optimize fuel efficiency. Overall, this car is quite economical and well-suited for long-term urban commuting.

As a car enthusiast, the fuel consumption data of the 09 Civic is quite straightforward: the 1.8L i-VTEC engine averages about 25 miles per gallon (mpg) in the city, equivalent to 9.5 liters per 100 kilometers (L/100km), and reaches 34 mpg on the highway, approximately 7 L/100km. The engine design prioritizes efficiency, and when paired with the CVT transmission, it minimizes power loss. However, real-world driving conditions like wind resistance and urban traffic congestion can increase fuel consumption by 15-20%. Therefore, don’t overlook regular throttle body cleaning and using low-viscosity oil. I’ve tested various road conditions and found that smooth driving and reducing idle time can significantly improve fuel economy, reflecting ’s reliability philosophy. With proper maintenance, the car can easily last a decade.

From a cost-saving perspective: The 09 Civic's fuel consumption is not too high, averaging about 10 liters per 100 km in the city and only 8 liters on the highway. While slightly less efficient compared to modern cars, a full tank can still cover over 500 km. As an economical user, I recommend traveling light and monitoring the fuel gauge—for example, avoiding full AC usage or sudden acceleration can save a few dollars daily. When choosing a car, consider tire pressure and curb weight, along with regular air filter replacements. The overall cost is low and practical, making it suitable for budget-conscious commuters.

Buddy, my 2009 Civic has been running for a few years, and the fuel consumption is honestly decent. It's around 10 liters in the city, and drops to a bit over 8 liters on the highway. Turning on the AC or during hot weather might slightly increase it, but just avoid flooring the gas pedal too often and you'll be fine. Replacing the spark plugs or cleaning carbon deposits can help you save some more fuel. It's simple and reliable to maintain, making it a great entry-level choice. New drivers can easily get the hang of it without breaking the bank.

Our family has been using a 2009 Civic for ten years, with consistently stable fuel consumption. It averages 9-10 liters per 100 kilometers in urban areas and 7-8 liters on highways. Even when carrying the whole family or going on long trips, we don't worry about soaring fuel costs. The key lies in sticking to regular maintenance—checking the fuel system and tire pressure every six months—and driving smoothly to avoid waste. In the long run, it has proven highly reliable with low maintenance costs. Choosing it as a family car strikes a balance between safety and economy, and its fuel consumption remains almost unchanged even after years of use.
