Why Does the Tiggo 3 Consume More Fuel Over Time?
3 Answers
The main reasons why the Tiggo 3 consumes more fuel over time are: Engine Carbon Buildup: During long-term operation of the vehicle, gasoline inevitably produces carbon deposits and sludge during combustion. If these deposits and sludge are not cleaned in time, they will lead to increased fuel consumption. Spark Plug Failure: The function of a car's spark plug is to generate an electric spark with high voltage to ignite the air-fuel mixture. If the spark plug is damaged, it will reduce the ignition energy, causing uneven combustion of the mixture, which will result in slower acceleration and increased fuel consumption. At this point, it is necessary to promptly inspect and replace the spark plugs. Abnormal Tire Pressure: Abnormal tire pressure in a car can also affect fuel consumption. When the tire pressure is too low or the tread is severely worn, the contact area between the tire and the road surface increases, leading to greater friction, higher rolling resistance, and naturally higher fuel consumption. Conversely, excessively high tire pressure can have some fuel-saving effects, but this will reduce the ride comfort and pose a risk of tire blowouts. Therefore, drivers should also pay attention to whether the tire pressure is normal while driving.
I think the increased fuel consumption of my Tiggo 3 is closely related to my driving habits. When I first bought the car, the fuel consumption was quite low. But as time went by, I became lazy about checking the tire pressure. After a month or two of neglect, the tire pressure dropped several pounds below the standard value, significantly increasing the rolling resistance of the car and naturally burning more fuel. Additionally, frequent stop-and-go traffic in the city makes me press the accelerator harder to save time, putting more burden on the engine. Maintenance has also been a setback—I haven’t changed the air filter for half a year, and it’s full of dust, making it hard for the engine to breathe. The spark plugs have also aged, causing delayed ignition and wasting fuel. By recording my driving data, I found that fuel consumption drops significantly during highway cruising. I recommend everyone develop the habit of checking tire pressure and filters every thousand kilometers—don’t be lazy like me.
From the perspective of vehicle aging, the increased fuel consumption of the Tiggo 3 is mainly due to engine issues. Carbon deposits gradually accumulate, dirtying the combustion chamber, which leads to increased fuel injection to maintain power. I didn’t pay attention before, and even felt a lack of power on the highway. Fuel filter clogging is also common, allowing impurities to enter the engine and reduce efficiency. Tire wear over certain mileage reduces grip, making rolling more fuel-consuming. Not changing the transmission oil for too long causes rough shifting, indirectly increasing fuel consumption. Solutions include regular throttle cleaning, filter replacement, and timely oil changes. By adjusting driving habits with monitoring app data, fuel consumption can stabilize quickly.
