So, you must know what factors affect efficiency and fuel economy. Some of the factors are listed below:
Quick acceleration & heavy braking
Heavy braking and quick acceleration reduces fuel economy by 33% on highways and 5% in towns. The reason is that when you quickly accelerate your vehicle, a continuous stream of fuel gets into engine to provide the speed you want. Similar is the case with heavy braking. Consider you are driving at a speed of 80 miles/second and suddenly you apply brakes, the fuel had already burnt but you didn't utilize the speed which the fuel could have provided.
Excessive idle time
Excessive idle time is another factor that constitutes a major hurdle in decreasing fuel economy. This is the case in towns where the traffic conditions are pathetic and your vehicle encounters heavy idle time.
Driving at higher speed reduces fuel economy
Driving at higher speed causes wind resistance that leads to reduced fuel economy. The concept is simple, when you drive in the opposite direction of the wind, a pressure on the vehicle causes the vehicle to use extra fuel to manage the speed. In other words, more fuel is consumed to travel the same distance as it would have when driving in the same direction of wind.
Cold Weather
Cold weather is also an important factor that reduces fuel economy. The reason is that in cold weather, the engine gets cold and as a result the engine is not able to start. This leads to continuous consumption of fuel until the vehicle gets started.
Deflated Tires
Deflated tires also results in reduction of fuel economy. Deflated tires causes more pressure on the tires of the vehicle resulting in reduced speed with more fuel consumption. Inflated tires also cause some reduction in fuel economy but not much. Inflated tires results in extra use of shockers when vehicle hits bumps on the road.
Dirty Filter or improperly tuned engine
A dirty filter is also a cause that results in lower fuel economy because a dirty filter results in dirt along with air. Also, if an engine is not properly tuned, then you will not get the desired fuel economy you want.
There are many other factors that are responsible for reduction in fuel economy. You can find more factors on the internet by searching on Google.
