Is the Old Mazda6 Fuel-Consuming?
3 Answers
The old Mazda6 with a 2.0L naturally aspirated engine has a combined fuel consumption of approximately 10 liters per 100 kilometers, which is relatively high for a 2.0L naturally aspirated engine. The old Mazda6 is a very classic car with many fans in China, and many modification enthusiasts also choose this car for customization. More details about the old Mazda6 are as follows: 1. Detail One: The old Mazda6 is equipped with a 2.0L naturally aspirated engine, which has 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, 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, while the rear suspension uses a multi-link independent suspension. The front suspension also includes a stabilizer bar. The Mazda6 is often referred to by many car enthusiasts as the 'King of Corners' due to its excellent cornering performance. Although the engine power of this car is not very strong, its chassis tuning is outstanding.
Anyone who's driven an old Mazda6 knows its city fuel consumption can be frustrating. My 2008 2.0L manual model would guzzle 10-11L/100km in daily traffic jams, though it performed decently on highways at around 7L. Aging vehicles particularly thirst for fuel - deteriorating rubber components reduce air intake efficiency, while carbon buildup on oxygen sensors causes ECU miscalculations in fuel injection. After replacing spark plugs and air filters, plus regular fuel system cleaners, I've managed to keep consumption just over 9L now. Transmission matching also plays a role - the old 5AT's jerky low-speed gear shifts are noticeably less smooth than modern transmissions. While slightly thirstier than contemporaries like the Accord or Camry, its handling remains unquestionably superb.
A veteran mechanic with 15 years of experience shares insights on this issue. The MZR engine technology in the old Mazda6 isn't particularly advanced, especially the 2.3L version, which typically has a combined urban fuel consumption of 11-13 liters, and can be even higher when engine carbon buildup is severe. The most commonly overlooked factor is tire pressure—many owners forget to check it. For every 0.5 bar decrease in tire pressure, fuel consumption increases by 3%. A faulty carbon canister purge valve can lead to gasoline vapor leakage, and poor atomization due to clogged fuel injectors is also common. I recommend cleaning the throttle body every 30,000 kilometers, checking the condition of the ignition coils, and avoiding overly viscous engine oil. With proper attention to these maintenance details, even a 10-year-old car can maintain reasonable fuel efficiency.
