How to get the best gas mileage at the speed limit?
Observe the Speed Limit 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 $0.20 per gallon for gas. 4 Observing the speed limit is also safer.
What happens to the price of gas at 50 mph?
Cost/Gallon: When driving 50 mph, price per gallon is assumed to be the same as the pump price. At higher speeds, the estimated price per gallon is increased based on the additional fuel you use by driving faster.
What’s the average savings on gas per gallon?
* Average savings, assuming drivers are willing to slow down 5 to 10 mph and fuel costs $3.02 per gallon. Hauling cargo on your roof increases aerodynamic drag (wind resistance) and lowers fuel economy.
What kind of cars get the most gas mileage?
Almost all are conventional gasoline-powered vehicles. Only one diesel and two hybrids are included; no plug-in hybrids or electric vehicles were tested. These estimates work best for well-maintained modern gasoline light-duty vehicles and will likely be less accurate for diesels, hybrids, and vehicles with cylinder deactivation.

Which is better 30 miles per gallon or 30 mpg?
For instance, if your vehicle gets 30 mpg, it travels 30 miles per one gallon of gas. The mpg is usually higher on highways compared to city driving since city driving necessitates slower speeds, idling, and higher revolutions per minute (rpm). According to Autolist, most vehicles achieve at least five more mpg on the highway than in the city.

How does speed affect the gas mileage of a car?
In our tests we’ve found that driving faster on the highway can really take a bite out of a car’s fuel efficiency. We measured gas mileage while driving at a steady 55, 65, and 75 mph in a Honda Accord, a Toyota RAV4, and three versions of a Ford Fusion, including a hybrid. The drop in fuel economy while speeding up from 55 to 65 was 4 to 8 mpg.
