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 $0.23 per gallon for gas.4
Observing the speed limit is also safer.

What driving technique helps save fuel? ›
One of the most effective ways to save fuel is to practice smooth acceleration and braking. Sudden starts and stops not only consume more fuel but also wear out your vehicle's engine and brakes faster. When you accelerate gently and anticipate stops, you can significantly improve your fuel efficiency.
What is the fuel saving trick? ›
Drive evenly.
Avoid hard acceleration and braking whenever possible. In our tests, frequent bursts of acceleration and braking reduced an older Toyota Camry's mileage by 2 to 3 mpg. Once up to speed, maintain a steady pace. The harder you accelerate, the more fuel you use.
What's the best speed to drive to save gas? ›
Midsize conventional gasoline cars achieve their best fuel economy at 55 mph. The fuel economy of midsize conventional diesel cars declines gradually from 45 to 55 mph and then drops quickly thereafter. The midsize hybrid electric vehicle loses efficiency more evenly between 45 and 75 mph.

What wastes the most gas in a car? ›
Idle is one of the biggest culprits when it comes to fuel consumption. Idling is one of the main reasons the automatic Stop/Start technology was invented.
Does AC waste gas? ›
Yes: The alternator, which is powered by the engine, is what provides energy to the air conditioner. The engine runs on fuel, meaning you are using up gas when you run the AC. With that said, enjoying a bit of cool air doesn't necessarily mean you're being inefficient.
Does turning off the AC save gas? ›
Does AC affect gas mileage? As a general answer, a Consumer Reports study found that, yes, running the AC does reduce gas mileage. Here are some tips to help you balance your fuel consumption with comfort. Generally, the air conditioner uses gas, so use it wisely.
Aggressive braking and accelerating
Speeding around and braking and accelerating aggressively burn much more fuel than driving smoothly. Fuel consumption is at its highest when accelerating because the engine has to work extra hard to keep pushing the car forward.

What is the secret to fuel efficiency? ›
Drive Sensibly
Aggressive driving (speeding, rapid acceleration and braking) can lower your gas mileage by 33 percent at highway speeds and by 5 percent around town. Anticipate traffic situations and maintain adequate spacing between vehicles to avoid unneces- sary braking and acceleration.
How to drive fuel efficiently manually? ›
Make sure you drive smoothly and don't accelerate too fast. Read the road ahead to avoid unnecessary braking. Slamming down hard on the brakes can affect fuel efficiency. Slow down gently by releasing the accelerator in time and leaving the car in gear unless you are stuck in bumper-to-bumper traffic.

How can you improve your gas mileage by driving? ›
Avoid speeding and rapid acceleration. Fuel efficiency drops significantly at higher speeds, and constantly hitting the gas uses more fuel than maintaining a steady pace. Accelerate gently and avoid slamming on the brakes. Anticipate stops and traffic lights so you can slow down gradually.
