Will a Damaged Catalytic Converter Increase Fuel Consumption?

[LeAnthony]

The catalytic converter itself does not directly affect fuel consumption. However, if the catalytic converter becomes clogged, leading to a loss of engine power, fuel consumption may increase. Below are specific details regarding fuel consumption: Factors affecting fuel consumption: Poor driving habits, such as aggressive lane changes, sudden stops and starts, or driving at high speeds in low gears, can all contribute to increased fuel consumption. Engine carbon buildup: Excessive carbon deposits in the engine can also lead to higher fuel consumption. Low tire pressure: Underinflated tires or insufficient tire pressure can increase vehicle fuel consumption. Overloaded trunk: Carrying too many items in the trunk can also result in higher fuel consumption. Methods to reduce fuel consumption: Maintain a steady speed while driving and avoid sudden braking or acceleration. Regularly maintain your vehicle.
