What are the reasons for the high fuel consumption of the Teana?

The reasons for the high fuel consumption of the Teana: If the high fuel consumption is not caused by a car malfunction, it is mainly related to the driver's personal driving habits, vehicle load, tire pressure, and travel route planning. Reducing fuel consumption also requires starting from these aspects. The following is the method for calculating fuel consumption: Calculate fuel consumption based on the relationship between distance and speed. 1. Record the mileage: Fill the car with fuel until the pump stops automatically, and record the current mileage. 2. Record the amount of fuel added: The next time you refuel, fill it until the pump stops automatically again, and record the amount of fuel added. 3. Calculate using the formula: Calculate the distance traveled since the last refueling, and then determine the fuel consumption based on the relationship between distance and speed.
My Teana's fuel consumption suddenly skyrocketed before, and I found out it was due to worn-out spark plugs. The manufacturer's claim that they last 100,000 km is totally bogus. Traffic jams also guzzle fuel—once I used an OBD scanner and saw the average speed was only 18 km/h. In such conditions, a 2.5L engine will easily consume 11L/100km. Carbon buildup in the throttle body is another headache; after cleaning it, the idle RPM stabilized noticeably. Oh, and my trunk always carries two cases of mineral water plus a golf bag, which adds weight equivalent to an extra adult. Switching to full synthetic oil made the throttle response much crisper, and my city commute fuel consumption dropped from 13L to 10L/100km. Keeping tire pressure at 2.6 bar (0.2 higher than factory recommendation) noticeably reduced rolling resistance.
