Why does the Chery Tiggo 7 have high fuel consumption?
2 Answers
There may be several reasons for the high fuel consumption of the Chery Tiggo 7: 1. Aging spark plugs: Incomplete combustion of gasoline. 2. Tire issues: Worn tires or insufficient tire pressure. 3. Aging oxygen sensor: High fuel consumption can be caused by excessive carbon deposits in components such as the throttle, idle motor, intake valve, intake pipe, combustion chamber, spark plugs, and fuel injectors. These carbon deposits can block the idle channel, causing the idle motor to stick or exceed its adjustment range, leading to low idle speed, unstable idle, high fuel consumption, and stalling. Additionally, frequent starting and stopping, infrequent gear shifting, and heavy throttle application can also contribute to high fuel consumption.
As an experienced driver who often helps friends check their car conditions, I've noticed that the high fuel consumption of the Tiggo 7 is often related to driving habits. Many owners tend to accelerate aggressively with heavy throttle, keep the air conditioning on while idling at red lights for extended periods, or frequently make short trips in the city. Under these conditions, not just SUVs but even sedans will see a significant increase in fuel consumption. You can try anticipating road conditions in advance, gently pressing the throttle and minimizing brake usage, while keeping tire pressure between 2.3-2.5 bar. For instance, last week, my neighbor's Tiggo 7 with 50,000 kilometers on it had its carbon deposits cleaned and spark plugs replaced, resulting in a drop of over 1 liter in fuel consumption. Even the engine noise became noticeably quieter.
