Why Is My Gas Going Down So Fast?

Do you waste more gas going faster?

Reality: Fuel efficiency doesn’t really start to drop until you reach speeds higher than 60.

And how smoothly you drive makes much more of a difference on gas mileage than how fast.

According to the U.S.

Department of Energy (DOE), most cars’ fuel efficiency peaks at speeds from 35 to 60 miles per hour..

Is it better to drive fast or slow when low on gas?

The short answer: Nope. The reason: The common understanding is that going faster burns more fuel and therefore, the slower you drive, the less fuel your car will use, but this actually isn’t true. Most cars’ peak fuel efficiency occurs somewhere between 50-60 miles per hour.

What is the best speed for gas mileage?

65mphThe Energy Saving Trust says that the most efficient speed you can travel in a car in terms of achieving the best fuel economy is 55-65mph. Any faster, though, and the fuel efficiency decreases rapidly. For example, driving at 85mph uses 40% more fuel than at 70mph (oh, and it’s illegal too).

What time of day is gas cheapest?

If you’re trying to save money on gas, you may want to change the day of the week that you fill up.

It is dangerous to drive with a very low fuel level. Even just driving on low fuel can damage the fuel pump, as debris or contaminants from the gas that settle at the bottom of the tank will be sent through the fuel pump when the tank is empty.

Does driving 55 mph saves gas?

While each vehicle reaches its optimal fuel economy at a different speed (or range of speeds), gas mileage usually decreases rapidly at speeds above 50 mph. You can assume that each 5 mph you drive over 50 mph is like paying an additional $0.15 per gallon for gas. Observing the speed limit is also safer.
