For an average family sedan (around 1.8L displacement), this is considered normal. Below is relevant information about fuel consumption: 1. Introduction: Constant-speed fuel consumption refers to the fuel economy indicator when a car drives at a constant speed on good road conditions. Since constant-speed driving is a basic operating condition for cars on highways, and this type of fuel consumption is easy to measure, it is widely adopted. 2. Methods to reduce fuel consumption: (1) Summer air conditioning system checks are essential: Air conditioning malfunctions can be a significant cause of high fuel consumption. If the air conditioning cooling effect is poor, many people will increase fan speed and lower temperature to achieve a cooler effect. Given that air conditioning directly affects a car's fuel consumption in summer, owners must promptly maintain and inspect the air conditioning system. Besides air conditioning malfunctions, dust accumulation on the air conditioning radiator (condenser) can also directly impact cooling efficiency. Owners should clean the condenser promptly to ensure the air conditioning works in good condition. (2) Frequent hard braking is the main cause of high fuel consumption: Frequent hard braking is the primary reason for persistently high car fuel consumption. Data from hybrid vehicles with energy-storing capabilities show that their fuel consumption is about 40% lower than that of comparable models. This data also reflects that higher comprehensive urban fuel consumption is clearly related to frequent hard braking.
