2.3l Mazda6 has a fuel consumption of 12.5 liters per 100 kilometers. More information about Mazda6 is as follows: 1. Mazda6 is a sporty B-segment sedan under Mazda, with a wheelbase of 2675 mm, and dimensions of 4670 mm in length, 1780 mm in width, and 1435 mm in height. 2. Mazda6 is equipped with two engines, one is a 2.0-liter naturally aspirated engine, and the other is a 2.3-liter naturally aspirated engine. 3. Mazda6 uses a double-wishbone independent suspension at the front and a multi-link independent suspension at the rear. The front suspension is also equipped with a stabilizer bar.

Back in my younger days, I drove a 2004 Mazda6 2.3 as my daily commuter, and its fuel consumption was quite noteworthy in my actual driving experience. In city driving, the fuel consumption typically ranged between 10 to 12 liters per 100 kilometers, especially during rush hour traffic jams where prolonged engine idling could push it close to 13 liters. On the highway, maintaining a steady speed could bring it down to around 7.5 liters, which was quite impressive. Overall, the average fuel consumption was a bit over 9 liters per 100 kilometers. To optimize fuel efficiency, I believe the key lies in driving habits, such as gently pressing the accelerator to avoid sudden acceleration and anticipating road conditions to reduce frequent braking. Additionally, regular maintenance is crucial—changing the engine oil and air filter on schedule ensures smoother engine operation. Keeping tire pressure at the standard level, neither too low nor too high, can also save about 0.5 liters of fuel. Although the car was a bit old, its engine was very sturdy. I drove it for five years without any major repairs, and as long as it was well-maintained, the costs were manageable. Occasionally, on long trips, the fuel consumption could drop below 7 liters, making its overall performance quite reliable for an older vehicle.

As an enthusiast who frequently tinkers with engines, I've gained some insights into the fuel consumption of the Mazda6's older 2.3-liter engine. This engine is conservatively designed, with urban fuel consumption around 11 liters per 100 kilometers, highway cruising stabilized at 7.8 liters, and a combined average fluctuating around 9 liters. It employs a multi-point fuel injection system, but as the vehicle ages, combustion efficiency tends to decline—factors like spark plug carbon buildup or dirty intake ducts can increase fuel consumption by approximately 1 liter. I recommend regular inspections of ignition coils and throttle body cleaning, along with using high-quality synthetic oil to improve fuel economy. Tire wear or installing oversized rims can also increase drag, raising fuel consumption by over 0.3 liters. Keeping the vehicle's load light, especially by emptying the trunk, can optimize long-distance performance. Overall, with proper maintenance, this engine can continue to operate efficiently for many years, keeping fuel consumption within reasonable limits.

From an environmental perspective, the fuel consumption issue of the older Mazda6 2.3 model shows higher emissions, with an average combined fuel consumption of 9 liters per 100 kilometers, meaning higher carbon emissions per kilometer compared to modern hybrid vehicles. As someone who cares about ecology, I've learned to reduce actual fuel consumption through smooth driving by avoiding sudden acceleration, which can bring city driving consumption below 10 liters. Reducing extra vehicle weight and regularly adjusting tire pressure can further minimize emissions. Although older cars consume more fuel, extending their usage cycle to avoid premature scrapping can overall support sustainability. Simple maintenance like replacing filters can also slightly improve efficiency.
