How to Deal with Unchanged Average Fuel Consumption?
3 Answers
After aggressive driving for a period of time, the average fuel consumption will increase. Good driving habits will gradually reduce the average fuel consumption until it stabilizes at a certain value. If it's a multifunction steering wheel, adjust the instrument display to the average fuel consumption position and press the OK button for a long time. If not, press and hold the 0.0 button in the middle of the instrument panel.
After driving for so many years, if I find that the fuel consumption remains consistently high without any change, there must be something wrong. The simplest thing is to check the tire pressure. Insufficient tire pressure increases rolling resistance, which is particularly fuel-consuming. Remember to keep a small air pump handy for topping up anytime. A dirty air filter can also hinder air intake efficiency, so it's best to replace it every five thousand kilometers. Driving habits need to be adjusted—avoid frequent rapid acceleration and hard braking. Maintaining a steady speed on the highway is actually the most fuel-efficient. Quickly clear out any unnecessary heavy items from the trunk; a lighter car means less burden. Regularly inspect the spark plugs; severely eroded ones have poor ignition efficiency. Engine oil should also be changed on time—if the viscosity is too high, it increases engine resistance. Give the car a small maintenance session on the weekend, clean the throttle valve carbon buildup, and the fuel consumption should definitely drop a bit.
When encountering persistently high fuel consumption, I usually start by checking the vehicle maintenance records. The engine condition is crucial - a dirty air filter increases intake resistance, and regular replacement can improve combustion efficiency. Insufficient tire pressure directly affects rolling resistance, so I recommend keeping a pressure gauge in the car for regular checks. Pay attention to oil viscosity too; oil that's too thick increases internal resistance - always use the type specified in the manual. Adjusting driving habits is also effective: minimize sudden acceleration and hard braking, and maintaining steady speeds in urban conditions saves the most fuel. Vehicle load control matters too - clean out unnecessary items from the trunk promptly. If these measures don't improve consumption, it might be necessary to check whether the oxygen sensor or fuel injectors are functioning properly.
