Why is the fuel consumption of Geely Boyue getting higher and higher?
4 Answers
There are generally several reasons for a sudden increase in fuel consumption: 1. Severe carbon deposits and poor fuel quality, or frequent use of fuel additives, can lead to increased carbon buildup inside the engine. Excessive carbon deposits can make the intake manifold rough, affecting the air intake and the mixture effect. If you notice increased fuel consumption along with reduced power and acceleration vibrations, it may indicate excessive carbon deposits that need cleaning. 2. The ignition system, including the ignition coil and spark plugs, is one of the common sources of faults. A faulty ignition coil can cause the ignition system to malfunction, resulting in cylinder misfires, reduced power, and increased fuel consumption. Spark plugs are also wear-and-tear parts; prolonged use without replacement can degrade ignition performance, leading to incomplete fuel combustion. Therefore, spark plugs should be replaced regularly. 3. Maintenance issues such as too much or too little engine oil, poor-quality oil, excessive viscosity, or not changing the oil on time are critical factors affecting engine performance. Always use high-quality oil that meets your vehicle's specifications and change it on schedule. Additionally, a dirty air filter can clog the intake tract, increasing intake resistance, reducing power, and increasing fuel consumption. 4. The oxygen sensor, located in the vehicle's exhaust pipe, is a ceramic component that detects and controls the oxygen-to-fuel ratio. The oxygen sensor monitors exhaust gases to regulate the fuel injection system. If the oxygen sensor fails, it can affect the fuel supply, causing a significant rise in fuel consumption. In such cases, it's necessary to check whether the oxygen sensor is damaged.
After driving for so many years, I've noticed that my Geely Boyue's fuel consumption has been increasing, probably because my driving habits have become more aggressive. I used to drive steadily with smooth acceleration, but now I often step on the gas pedal hard and brake suddenly when I'm in a hurry, which naturally burns more fuel. Another possible reason is insufficient tire pressure. Last month when I checked, it was significantly lower, making the wheels harder to turn and consuming more fuel. Using the air conditioner too frequently is also an issue, especially in city traffic jams, as it puts more load on the engine. I suggest checking the tire pressure and air conditioner settings first, then trying gentle driving for a week to see if the fuel consumption drops. Regularly adding some cleaning agent to clean the fuel system can also help prevent carbon buildup from worsening fuel consumption. In short, starting with daily habits is the easiest solution; if that doesn’t work, then consider repairs.
My Boyue's fuel consumption has increased, and I think it's due to inadequate maintenance. The air filter is clogged, causing poor airflow and reduced engine efficiency. The spark plugs are old and misfiring—I replaced them last year, but they've degraded over time. Also, the exhaust gas sensor (oxygen sensor) might be malfunctioning or improperly calibrated, leading to excessive fuel injection. I usually replace the filter myself and clean the intake pipe carbon deposits, which can improve things significantly. If the engine oil isn't changed frequently enough, it affects lubrication and increases fuel consumption—generally, it's recommended to change it every six months or 8,000 kilometers. If all these checks don't resolve the issue, there might be a delayed response problem with the transmission, requiring a mechanic to diagnose and adjust it with a computer scan. Don't wait for a small issue to become a big one—repairs will cost more.
I feel the fuel consumption of my Boyue is getting higher for commuting, probably due to temperature changes. In winter, the cold weather leads to longer engine warm-up times and higher fuel consumption, while in summer, using the air conditioning adds extra load. Poor road conditions are also a factor; frequent stop-and-go traffic in the city definitely consumes more fuel than driving on highways. I've noticed that adding a roof box or carrying heavy luggage also reduces efficiency. Using engine oil with the wrong viscosity can increase resistance, so choosing seasonal oil is important. I recommend resetting the fuel consumption statistics before each refuel to track trends and confirm if consumption is really increasing. Try to drive more on highways to reduce sudden stops and starts, and regularly check tire wear to save fuel. Safety first—if anything seems off, don’t delay getting it checked.
