Why does the new Sylphy suddenly have high fuel consumption?
2 Answers
The sudden increase in fuel consumption of the new Sylphy is usually due to carbon deposits inside the engine after driving more than 40,000 kilometers. The fuel consumption of this car is generally around 8, and if it suddenly increases, it may be caused by some component failure. The reasons for the sudden increase in fuel consumption of the new Sylphy are as follows: 1. Insufficient or low tire pressure: (1) It will increase the friction between the tires and the ground, increase resistance, and increase fuel consumption. (2) Severe tire wear will often cause slipping, and fuel consumption will also increase. 2. Poor gasoline quality will increase carbon accumulation: (1) Excessive carbon will make the intake pipe wall rough. (2) It will affect the intake effect and the quality of the mixture, causing a sharp increase in fuel consumption. 3. Very congested driving conditions: (1) It will lead to high fuel consumption because the engine is relatively large when the vehicle moves from a standstill. (2) Because it is necessary to overcome the friction of the ground, the fuel injection volume will also increase, so the fuel consumption will also be very high.
I also drive a Sylphy and was really troubled by the sudden surge in fuel consumption. Later, I found out it was a tire pressure issue—because the weather turned cold and I didn’t refill the tires in time, the rolling resistance increased, naturally driving up the fuel consumption. I recommend developing a habit of checking tire pressure weekly and keeping it around 230kPa. Another small tip is to avoid short trips, as the engine consumes more fuel when it’s just warmed up and you’ve already reached your destination—try combining trips instead. I’ve also found that cleaning the air filter helps, but the most important thing is to monitor your driving habits, like easing off the throttle early at red lights and avoiding sudden braking. These small changes can save you a lot of money.
