What to Do If the Baojun 730 Consumes Too Much Fuel?
2 Answers
It is recommended to regularly inspect and maintain the vehicle, and clean or replace the three filters (air filter, oil filter, and fuel filter). Below are detailed explanations of the reasons why a vehicle may consume increasing amounts of fuel and their corresponding solutions: 1. Increasing carbon deposits in the engine: Carbon deposits are produced due to incomplete combustion of fuel. They can accumulate not only in the engine but also in the intake manifold, intake valves, and throttle body. Solution: Perform cleaning of carbon deposits in the cylinders and intake system. 2. Decreased efficiency of spark plugs and ignition coils: This can lead to insufficient engine power and increased fuel consumption. Solution: Replace the spark plugs and ignition coils. 3. Carbon deposits on the fuel injectors: Carbon deposits on the injectors can cause incomplete fuel atomization, preventing proper mixing of fuel and air, resulting in reduced vehicle power and increased fuel consumption. Solution: Clean the fuel injectors.
My Baojun 730 has been consuming more fuel after long-term use, but don’t rush into major repairs just yet. I usually start by checking my driving habits—every time I accelerate hard or brake suddenly, the fuel gauge drops noticeably. Maintaining a steady speed and anticipating road conditions in advance can significantly reduce fuel consumption. Running the AC in summer does consume more fuel, but keeping it at a moderate setting rather than maxing it out minimizes the impact. Regularly checking tire pressure is crucial; underinflated tires create more rolling resistance, leading to higher fuel consumption. During my last maintenance, I replaced the air filter and cleaned out carbon deposits, which helped me get an extra few dozen kilometers per tank. Fuel quality also matters—avoid cheap, low-quality gas from small stations, as incomplete combustion leads to more carbon buildup, creating a vicious cycle of higher fuel consumption. Develop the habit of warming up the car for no more than one minute, and if idling exceeds three minutes, it’s better to turn off the engine. If fuel consumption remains high after addressing all these factors, then it’s time to check components like spark plugs and oxygen sensors.
