Why is it important to know the fuel efficiency MPG of your car?

MPG is an important metric to know about any vehicle that you’re considering purchasing. It tells you about the difference in cost between operating different vehicles by giving you a sense of how much money you’re likely to spend on fuel.

How accurate is the MPG display?

Over hundreds of vehicles tested, we have only seen the display be accurate a handful of times. Most of the time, the MPG display you see in your dash display is telling you your mileage is about 10 to 15\% better than it actually is.

How much of a difference does MPG make?

For example, it is easy to see in the example given above that improving from 10 to 11 MPG is a 10\% improvement; 16.5 to 20 MPG is a 20\% improvement; and 33 to 50 MPG is a 50\% improvement. Although they all represent different percentage improvements in MPG, they all save 100 gallons of gas over 10,000 miles.

Do you get better gas mileage when your tank is full?

Filling both tanks means an awful lot more fuel is carried around, and hence a more pronounced saving. Assuming an average speed of 40kmh, you would save nearly 14 minutes by filling up half as much, twice as often.

Does gas mileage really matter?

Fuel-economy improvements from 12-20 mpg are significant. Once vehicles get over 25 mpg, the gains are much less dramatic. While extremely high-mileage hybrids provide eco bragging rights, they don’t save much more gas than midsize sedans.

What average MPG means?

What is the MPG illusion?

In general, MPG Illusion suggests that consumers are likely purchasing both too many gas guzzlers and too many super-efficient plug-in hybrids, and avoiding vehicles with mid-range MPG ratings more than they would if they weren’t under the MPG Illusion.
