Is the fuel consumption of the old Mazda 6 very high?

The old Mazda 6 with a 2.0-liter naturally aspirated engine has a combined fuel consumption of about 10 liters per 100 kilometers, which is relatively high for a 2.0-liter naturally aspirated engine. The old Mazda 6 is a very classic car with many fans in China, and many modification enthusiasts also use this car for modifications. More details about the old Mazda 6 are as follows: 1. Detail one: The old Mazda 6 is equipped with a 2.0-liter naturally aspirated engine with a maximum power of 108kw, a maximum torque of 183 Nm, a maximum power speed of 6500 rpm, and a maximum torque speed of 4000 rpm. This engine uses an aluminum alloy cylinder head and block, and is paired with either a 6-speed manual transmission or a 5-speed automatic transmission. 2. Detail two: The front suspension of this car uses a double-wishbone independent suspension, and the rear suspension uses a multi-link independent suspension. The front suspension also includes a stabilizer bar. The Mazda 6 is called the 'King of Corners' by many car enthusiasts, and its cornering performance is indeed excellent. Although the engine power of this car is not very strong, its chassis tuning is outstanding.
I've been driving an old Mazda6 for several years, and honestly, the fuel consumption isn't exactly low. In city traffic with the AC on, it can go up to 11-12 liters per 100 km, especially on roads with frequent traffic lights. On the highway, it's a bit more economical, around 8 liters, but it's definitely worse compared to current turbocharged models. The car's 2.0L naturally aspirated engine is quite old, and the vehicle is relatively heavy. Some owners also report that as the car ages, carbon buildup in the fuel system can further increase fuel consumption. However, with regular cleaning of the throttle body, replacing the air filter, and keeping the tires properly inflated, it's possible to keep daily driving under 10 liters per 100 km. Don't compare it to hybrids—given that it's an older model, this performance is still acceptable.
I helped a friend refurbish an old Mazda6, and I feel fuel consumption depends on the situation. For a well-maintained manual transmission, 9-10 liters per 100km in the city is normal. The automatic transmission has slow response and less intelligent shift logic, often revving high, so burning 1-2 liters more isn’t surprising. Maintenance condition is key—if spark plugs are worn or the oxygen sensor fails, fuel consumption can suddenly increase by 15%. Driving habits also make a big difference; many people like to accelerate hard from a start, and since this car delivers power at high revs, it’s especially thirsty in the city. Switching to lower-viscosity oil and traveling light can help keep fuel consumption within a reasonable range.
