The Energy Saving Trust says the most efficient speed you can travel in a car in terms of achieving the best fuel economy is 55 to 65 mph. However, faster and fuel efficiency decreases rapidly. For example, driving at 85 mph consumes 40% more fuel than at 70 mph (oh, and it's also illegal). Even with a fuel efficiency of more than 45 mpg, you shouldn't drive at more than 70 mph if you want to save money.
So as you prepare to hit the road to the beach, visit grandma, or just see America from the road, it's worth quickly reviewing the best ways to increase your mileage. The only problem is that much of what you've been told about increasing mileage is a myth. Here we debunk six of the most widely believed misconceptions about mileage. On the other hand, switching to normal in a car for which “premium fuel is required”, as it is for some high-performance luxury trips, could cause notable shocks.
And over time, that could lead to faster engine wear. Consumer Reports thoroughly tested this theory using its own underground tank, similar to those used by gas stations. They found that it is surprisingly difficult to accurately predict whether a given tank filled with gas will be cold or hot. For starters, if the gas was at a certain temperature when it was delivered from the tanker, it tended to stay at that temperature for a while, even after it had been transferred.
Not only that, but the first gas that is pumped on a given day could be hot, since a certain amount of gas accumulates in the aerial bomb. So even if you manage to be the first customer of the day, you may still buy hot gas. After all that, even if you are successful in buying cold gas, the density difference is so small, perhaps a maximum of 1 percent per fill, according to Consumer Reports, that the savings are marginal. The AAA TripTK trip planner not only gives you point-to-point driving directions, but it also allows you to highlight gas stations along your route, including frequently updated gas prices for each location.
You'll need to zoom in to get a pretty detailed view of your route, but the tool lets you plan ahead where to stop for gas instead of wandering around looking for good prices. You don't even have to be a member of AAA to use the feature. UU. (DOE), fuel efficiency of most cars peaks at speeds of 35 to 60 miles per hour.
However, after 60, fuel efficiency drops significantly; the DOE says every 5 miles per hour you drive above 60 is like paying an additional 24 cents per gallon for gasoline. This is because, at higher speeds, your car finds more wind resistance and tires find more rolling resistance. After the previous oil embargoes, there was a rush in cars with manual transmissions because they got better mileage than automatic ones. But that's less true today, especially at highway speeds, says Gabriel Shenhar, senior automotive test engineer at Consumer Reports.
The old three-speed automatic had to work much more at highway speeds than the current four- or five-speed automatic. And the new automatics produced in recent years have an “overdrive upper gear” that reduces engine rpm at higher speeds. The air conditioner does burn gas, so Ford recommends that you at least turn off the air conditioner and use the “ventilation” settings of your climate control as much as possible. According to Ford's website, Driving Skills for Life, reducing air conditioning use can save up to 10 to 15 percent on fuel.

While each vehicle achieves its optimal fuel economy at a different speed (or range of speeds), gasoline mileage generally decreases rapidly at speeds above 50 mph. In our tests, we found that driving faster on the road can actually affect a car's fuel efficiency.
It's usually a Toyota Prius, or some other hybrid owner, that's taking their time to get to their destination or doing everything they can to save as much fuel as possible. Don't replace your tires too soon in an effort to chase the pennies that low-rolling resistance tires can save on fuel. Drivers can save fuel by learning how different driving behaviors affect fuel economy and adopting techniques to save fuel and money. While you might think that driving at the speed limit and accelerating smoothly are the only ways to save fuel, there are other ways to get better mileage out of your car.
Combining trips can save you time and money by avoiding unnecessary stops and starts of your vehicle, which can be a problem in colder climates, where the engine takes longer to reach the most fuel-efficient temperature. While vehicles achieve optimal fuel economy at different speeds, mileage generally decreases rapidly at speeds greater than 50 miles per hour (mph). Here are some tips on fuel-efficient driving that will not only reduce emissions of greenhouse gases and other pollutants, but could also save you hundreds of dollars a year in fuel costs. On long stretches of highway driving, cruise control can save fuel by helping your car maintain a consistent speed.
Using cruise control on the road helps you maintain a consistent speed and, in most cases, will save gas. A study conducted in Japan showed that small variations in speed increase fuel consumption by up to 20-48%. When traveling over mountainous terrain and where traffic permits, allow your car to slow down naturally when traveling uphill and accelerate again when you go downhill. In fuel-injected vehicles, taking your foot off the accelerator automatically stops the flow of fuel to the engine until the engine speed drops to idle when you start again to ensure that the car does not stall.
In fact, the pressure you put on the accelerator will have a greater effect on the mileage of your car, whether you are driving at a fast speed or not. . .
