Is the fuel consumption of the old Mazda 6 high?

The comprehensive fuel consumption of the old Mazda 6 is about 10 liters per 100 kilometers, which is relatively high. More information about the Mazda 6 is as follows: 1. The Mazda 6's exterior design features an oval front face inspired by sports cars, combined with a wide and low chassis, showcasing Mazda's strong dynamic feel. 2. The Mazda 6 is equipped with 2.0-liter and 2.3-liter inline four-cylinder engines. Its 2.3-liter four-cylinder engine utilizes Sequential Valve Timing (S-VT) and Variable Valve Timing (VVT) technologies, which can significantly improve engine power, output more torque, and provide greater performance.

The fuel consumption of the old Mazda6 really depends on the specific situation. My 10-year-old 2.0L automatic version consumes around 10-11 liters per 100km in city driving, and it can drop to just over 7 liters on the highway. These cars are all quite old now, so the engine condition is particularly crucial. Worn spark plugs or a faulty oxygen sensor can cause fuel consumption to skyrocket. In summer, with the AC on and stuck in traffic, it's not uncommon to see consumption hit 13 liters per 100km. However, among Japanese cars of the same era, its fuel consumption isn't particularly low, mainly because the 5AT transmission is considered outdated by today's standards. I recommend checking tire pressure and the air filter—these are the simplest factors but have a significant impact.

When I drove my old Mazda 6 for ride-hailing, I specifically tested the fuel consumption: the 2.3L automatic transmission model consumes at least 13L/100km in city driving, and can be reduced to 10.5L/100km with gentle driving. The most fuel-consuming part is frequent acceleration, as this car has weak low-end torque and often requires deep throttle input. Last time, while helping a fellow car owner diagnose high fuel consumption, I found the carbon canister purge valve was faulty, causing fuel tank vapors to directly enter the engine and waste fuel unnecessarily. Additionally, carrying too much clutter in the trunk can increase consumption by 0.5L/100km - with older cars, you really need to be meticulous about these details.

The fuel consumption of the old Mazda6 largely depends on the vehicle's condition. I've refurbished over twenty of them. A normal 2.0MT should consume around 9 liters per 100km; anything over 12 indicates a problem. Common issues include: a faulty rear oxygen sensor causing excessive fuel injection, leaking ignition coils leading to incomplete combustion, and a significant drop in transmission efficiency if the gearbox oil hasn't been changed in eight years. Last week, an owner reported high fuel consumption, which turned out to be due to switching to 235 wide tires—the original 205 width is sufficient.

After seven years of driving a 2.0L manual transmission, here's my summary: Gentle driving at 60km/h yields the best fuel economy at 6.8L/100km, but daily commuting with frequent traffic lights usually results in around 9.5L/100km. Winter consumption is about 0.5L higher than summer. Using 5W40 engine oil increases consumption by 0.3L compared to 0W20. I recommend regular throttle body cleaning for older vehicles - carbon buildup causes unstable idle and higher fuel consumption. Modified exhaust systems should be noted - insufficient backpressure reduces low-end torque and increases fuel consumption.

When I first took over my dad's 2008 Mazda 6, the fuel consumption was a shocking 14L. After replacing the iridium spark plugs and cleaning the fuel injectors, it immediately dropped to 10L. A special reminder: regularly change the fuel filter—mine was clogged, causing the fuel pump to work overtime. For older cars, it's recommended to use fuel system cleaner to remove carbon deposits; now it's basically maintaining 9.2L. The fuel consumption of this car varies depending on how it's driven—shifting at 3000 RPM versus 2000 RPM can make a 2L difference. Also, an aging AC compressor is a hidden fuel consumption killer.
