The MPG gage on your BMW dashboard displays the average fuel economy of your vehicle. It is measured in miles per gallon (mpg). The higher the MPG, the more miles your vehicle can travel on one gallon of gas.
The MPG gage is calculated by dividing the total distance traveled by the amount of fuel consumed. The distance traveled is measured by the vehicle's odometer. The amount of fuel consumed is measured by the fuel flow sensor.
The MPG gage can fluctuate depending on several factors, including:
* Driving conditions: The MPG gage will be lower if you are driving in stop-and-go traffic or in hilly areas. It will be higher if you are driving on the highway at a consistent speed.
* Vehicle speed: The MPG gage will be lower at higher speeds. It will be higher at lower speeds.
* Engine size: Vehicles with larger engines typically have lower MPGs than vehicles with smaller engines.
* Vehicle weight: Heavier vehicles typically have lower MPGs than lighter vehicles.
* Tire pressure: Underinflated tires can reduce MPG.
* Air conditioning use: Using the air conditioner can reduce MPG.
* Carrying extra weight: Carrying extra weight in your vehicle can reduce MPG.
The MPG gage can be a helpful tool for managing your fuel consumption. By understanding the factors that affect MPG, you can make adjustments to your driving habits and vehicle to improve your fuel efficiency.
