What are the reasons for the high fuel consumption of the eighth-generation Accord?

The reasons for the high fuel consumption of the eighth-generation Accord are: 1. The driver's own driving habits; 2. Excessive carbon deposits in the engine or spark plugs not being replaced for a long time. Taking the 2021 eighth-generation Accord as an example, it belongs to the mid-size car category, with body dimensions of length 4893mm, width 1862mm, height 1449mm, a wheelbase of 2830mm, a fuel tank capacity of 48.5 liters, and a curb weight of 1619kg. The 2021 eighth-generation Accord features a MacPherson strut front suspension and a multi-link independent rear suspension. It is equipped with a 2.0L naturally aspirated engine, delivering a maximum horsepower of 146ps, a maximum power of 107kW, and a maximum torque of 175Nm, paired with an electronic continuously variable transmission.
Hey, I've driven quite a few eighth-generation Honda Accords. If it suddenly starts consuming more fuel, it's mostly caused by carbon buildup in the engine. After driving for a long time, carbon deposits easily clog the intake valves and fuel injectors. When gasoline doesn't burn completely, it's like a blocked water pipe—fuel gets wasted for nothing. Check the spark plugs; if they're worn out and don't ignite properly, the combustion efficiency drops, leading to higher fuel consumption. I've seen cases where a clogged air filter was still being used—when air can't get into the engine, it has to compensate by injecting more fuel, causing fuel consumption to skyrocket. Low tire pressure is another sneaky culprit. If the pressure drops below the standard value, the rolling resistance increases, requiring heavier throttle input to move—how could that not waste fuel? My suggestion is to clean out the carbon deposits first, replace the spark plugs and air filter, and avoid aggressive driving. Usually, fuel consumption can be brought back down. Though these mechanical details might seem old-school, small issues can pile up and become major fuel-wasting culprits.
