Why Does the Tiggo 3 Consume More Fuel Over Time?
3 Answers
Tiggo 3 consumes more fuel over time due to reasons such as engine carbon buildup and spark plug failure. The details are as follows: Engine Carbon Buildup: During prolonged operation of the car, 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 role of the car's spark plug is to generate an electric spark with high voltage to ignite the air-fuel mixture. If damaged, the ignition energy decreases, causing uneven combustion of the mixture, which results 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 can also affect the car's 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 a certain fuel-saving effect, but this reduces the shock absorption comfort of the ride and increases the risk of tire blowouts. Therefore, drivers should also pay attention to whether the tire pressure is normal during driving.
I've been driving the Tiggo 3 for almost two years now. When I first bought it, the fuel consumption was quite low, around 7 liters per 100 km. But gradually, it increased to over 9 liters. I think the main reason is that my driving habits have worsened. Now, with high work pressure, I often brake and accelerate abruptly, stepping on the gas pedal aggressively, especially during rush hour traffic jams—constantly alternating between the gas and brake pedals, which naturally drives up fuel consumption. Another factor is falling behind on maintenance. Last year, I forgot to change the engine oil on time, leading to more carbon buildup inside the engine, which affected efficiency. Additionally, urban traffic congestion is getting worse, and I frequently use the air conditioner for short trips, which has noticeably increased fuel consumption. I remember once driving on a suburban highway, and the fuel consumption dropped to 7.5 liters, proving how much more fuel is consumed in city driving. My advice is to drive calmly, stick to regular maintenance, replace the air filter, and check tire pressure—it saves both fuel and money.
I have been driving the Tiggo 3 for over five years. Initially, the fuel consumption was stable at 8 liters per 100 km, but now it exceeds 10 liters. From my observation, the reasons include aging mechanical components. After running 100,000 kilometers, the spark plugs are worn, the piston rings don't seal tightly, and the engine's operational efficiency has decreased. Additionally, carbon deposits have built up in the fuel system without timely cleaning, affecting fuel combustion efficiency. Furthermore, the drive belt has loosened, and the transmission oil has thickened, increasing power loss. City traffic has become more congested, with frequent stops and starts leading to higher fuel consumption. I recall the first time fuel consumption spiked significantly was when I didn't change the transmission oil, but it improved after replacement. I recommend regular engine cleaning to prevent old issues from accumulating.
