Why Does Fuel Consumption Increase?
2 Answers
Excessive carbon deposits in the car engine, excessive air conditioning load, and untimely cleaning of dust on the car body. The following is a related introduction to the increase in vehicle fuel consumption: 1. Excessive carbon deposits in the car engine: The operation of a car cannot be separated from the combustion of gasoline. Gasoline inevitably contains some impurities, and long-term accumulation will form a certain amount of carbon deposits and sludge on the engine surface, which is harmful to the engine. It can easily lead to difficulties in starting, high idle speed, excessive exhaust emissions, and other issues, and will further increase the car's fuel consumption. 2. Excessive air conditioning load: Summer is the peak period for air conditioning use. After prolonged use, dust can easily accumulate in the air conditioning system, not only breeding bacteria but also causing unpleasant odors in the cold air blown out, which will further increase the car's fuel consumption. 3. Untimely cleaning of dust on the car body: The biggest resistance a car encounters while driving is air. If there is too much dirt and dust on the car body, it will increase the resistance during driving. The resistance caused by the dust on the car body will significantly increase the car's fuel consumption.
Having driven for over a decade, I've found that unexplained increases in fuel consumption are usually related to driving habits. For example, with the recent hot weather and constant air conditioning use in traffic jams, fuel consumption can be two to three units higher than usual. Or it could be low tire pressure—last time I didn't notice a slow leak, and it cost me an extra liter per 100 kilometers. Another scenario is carrying too much unnecessary weight, like two crates of bottled water sitting untouched in the trunk for six months—basically driving around with dumbbells every day. Many also overlook engine oil condition; overdue oil becomes as thick as syrup, making the engine work harder. I recommend checking these areas first. If nothing stands out, then look into parts like the oxygen sensor—after all, replacing one could cost several tanks of fuel.
