Is 12L Fuel Consumption Considered High?
1 Answers
For family sedans, a fuel consumption of 12L is relatively high. The factors contributing to high fuel consumption are as follows: Tire pressure below the standard level increases fuel consumption by raising the rolling resistance of the tires. This enlarges the contact area of the tires, increasing friction, which not only wears down the tire shoulders but also boosts fuel consumption. A full fuel tank increases the vehicle's weight, leading to higher fuel consumption. A malfunctioning thermostat or temperature control switch lowers the water temperature, increasing fuel consumption. Spark plugs that have been used for too long reduce ignition energy, slowing down acceleration and significantly increasing gasoline consumption. Prolonged idling without turning off the engine or frequent starts also increase fuel consumption. Rapid acceleration causes strong friction between the tires and the ground, accelerating tire wear. It also easily leads to engine carbon buildup, which can increase fuel consumption. If a vehicle hasn't been maintained for a long time, dirty engine oil and air filters can also lead to increased fuel consumption. Dirty oil results in poor lubrication, increasing resistance in the engine's moving parts and requiring more energy to overcome this resistance, thereby raising fuel consumption.
