How to Deal with High Fuel Consumption in the Sonata VIII?
2 Answers
Solutions for high fuel consumption in the Sonata VIII are as follows: 1. Adjust the appropriate air conditioning temperature: If the car air conditioning is set to the lowest temperature, the air conditioning pump will run continuously, and the blower will operate at high speed, leading to increased fuel consumption. Additionally, a large temperature difference between the inside and outside of the car can easily cause colds. Therefore, it is generally recommended to set the car air conditioning temperature at 25°C. 2. Develop good driving habits: The engine consumes fuel even when idling. During prolonged traffic jams or waiting periods, it is advisable to turn off the engine. However, the computer-controlled fuel injection volume is higher each time the engine is started, so frequent engine starts within a short period should be avoided. Rapidly pressing the accelerator not only consumes more fuel but also damages the engine. It is better to ease off the accelerator early when approaching a red light and minimize the use of brakes. Good driving habits not only maintain the car but also save fuel.
I also encountered the issue of soaring fuel consumption with my Sonata 8 a couple of days ago, and later found out it was the combined result of driving habits and maintenance problems. If you always love to floor the accelerator for sudden acceleration and constantly brake in city traffic jams, the engine load increases, naturally leading to higher fuel consumption. Also, never overlook tire pressure—I personally tested that a difference of 0.5 bar in tire pressure can waste an extra 7% of fuel. In terms of maintenance, timely replacement of the air filter is crucial. After I last changed my air filter, my fuel consumption dropped by 0.8 liters directly. Severe carbon buildup on spark plugs can also affect ignition efficiency. I recommend always filling up with regular 92-octane fuel from reputable gas stations and driving more steadily—your fuel consumption should stabilize around 10 liters per 100 km.
