What Causes the Fuel Consumption Display to Fluctuate Erratically?
1 Answers
During fuel sloshing in the tank, poor contact of the fuel level sensor (fuel float) can also affect the variation in average fuel consumption values. In such cases, it's important to observe whether the fuel gauge needle also fluctuates up and down. Insufficient energy in the ignition system, particularly from spark plugs causing ignition fluctuations, can lead to incomplete fuel combustion, resulting in erratic fuel consumption readings. Factors affecting fuel consumption include: 1. Rough Roads Consume More Fuel: Driving on congested or uneven roads for extended periods in lower gears inevitably increases fuel consumption; 2. Overloading the Trunk Increases Fuel Usage: Using the trunk as a storage space, cramming it with unnecessary items, increases the vehicle's weight. It's important to note that vehicle weight and fuel consumption are directly proportional. A 10% reduction in vehicle weight can lead to a corresponding percentage decrease in fuel consumption; 3. Incorrect Driving Habits Can Double or Triple Fuel Usage: Poor driving habits have the most significant impact on fuel consumption. During driving, especially in heavy traffic, at red lights, or when changing lanes, sudden acceleration and hard braking are the most common issues.
