Does Cruise Control Save Gas? Unveiling the Truth About Fuel Efficiency Car, Vehicle & Truck Guides and Repair Journals

Aftermarket cruise control kits typically include detailed installation instructions, and/or provide a direct phone number to the company’s technical support team. This eliminates much of the guesswork surrounding the installation of such systems. In most cases, an aftermarket cruise control kit can be easily and affordably added to almost any vehicle. In fact, a number of aftermarket suppliers currently manufacture and market a variety of kits for this exact purpose. Likewise, driving in stop-and-go traffic also requires a higher degree of concentration, as a significant amount of speed metering becomes necessary.
Where Should You Put Your Foot While Using Cruise Control?
The throttle controls the speed by regulating how much air is taken in by the engine. A small computer behind the dashboard or under the hood controls the cruise control. Hi, I'm Chris Brunson, and I'm passionate about diesel fuel and all things related to it. With over 5 years of experience in the industry, I've gained a deep understanding of diesel fuel properties, engine performance, and fuel efficiency. Through this blog, I hope to share my knowledge and insights with fellow diesel enthusiasts and provide a platform for discussion and learning. Let’s dive into some of the advantages you can enjoy when using cruise control on your journeys.
Advanced Cruise Control Systems
This way, you won’t have to burn much fuel while accelerating, and then slowing down right after. It lets you set up your driving speed precisely, and the same goes for slowing down. Have in mind that stepping on the brake pedal will shut down the cruise control feature. Mending your ways will save money even in times of low gas prices, as it will cut your spending on insurance rates and speeding tickets, too.
Saves Fuel
The more time you spend with the cruise control keeping youat a constant speed, the less fuel you will use. Engaging cruise control on the highway can help you use less gas as it helps maintain a constant speed, which is more fuel-efficient than constant accelerating and braking. Under normal driving conditions, however, cruise control can’t read the road like a driver can so it will ask more of your engine than might be necessary and use more fuel than driving normally.
Considerations for Road Conditions
Utilizing cruise control has the advantage of maintaining a consistent speed, which can lead to better fuel efficiency. When we drive manually, especially on long road trips, our speed tends to fluctuate. These changes can result in accelerated fuel consumption, while setting a steady speed with cruise control helps us save gas and money. When you engage cruise control, your vehicle maintains a constant speed, which helps optimize your fuel consumption. By eliminating unnecessary acceleration and deceleration, cruise control ensures that your engine operates at a consistent level of efficiency. This can lead to significant savings at the gas pump, especially during long highway drives.
Economic and Environmental Impact
Before delving into the fuel-saving aspect of cruise control, it’s important to understand how the system works. When activated, cruise control uses electronic sensors to monitor the vehicle’s speed and adjust the throttle accordingly to maintain the set speed. This eliminates the need for drivers to manually modulate the throttle pedal, resulting in a consistent speed and potentially reducing speed fluctuations that can impact fuel consumption.
Traffic Conditions
To use cruise control safely, it’s best to know when you should and shouldn’t use it. [9] Using cruise control on the highway makes your driving more predictable to other drivers. Instead of constantly changing speeds, cars know how fast you’re driving and can follow safely behind you or pass. Cruise control is most effective on long, open highways where there are minimal traffic disruptions. It helps to maintain a steady speed, reducing the need for frequent acceleration and deceleration. While it is true that maintaining a consistent speed can improve fuel efficiency, the benefits of cruise control may vary depending on the driving conditions.

Use Cruise Control on Highways
Without fabricating a new aluminum or carbon-fiber hood or doors, you can “lightweight” your own car by jettisoning all of those “just in case” items in your trunk and just carry a charged phone. Look farther ahead than the car in front of you to try and anticipate lights and stop signs so you can coast longer and brake less. And of course the most effective, least heeded or appreciated advice is to simply drive slower (see the first line of the paragraph above). Driving our 40 foot motorhome, I often use the cruise control whenever it is reasonable, primarily to relax my right leg and foot from the strain of pushing the pedal. However, once I encounter increased traffic, rain or hilly terrain, I turn it off.

It raises the question of whether this convenience also translates into fuel savings. Cruise control is a feature found in many modern vehicles that allows drivers to set a desired speed for their vehicle, which the car then maintains automatically. One common claim about cruise control is that it can help save gas, leading to increased fuel efficiency and potential cost savings for drivers. In this blog post, we will explore whether using cruise control actually leads to fuel savings, based on research and scientific analysis.
Unnecessary braking can have a negative impact on fuel efficiency, especially when using cruise control. When you encounter a downhill slope, cruise control can sometimes apply more braking than necessary, which leads to wasted energy. To optimize fuel efficiency, it’s important to be aware of the road ahead and disengage cruise control if you anticipate the need to brake. By allowing the vehicle to coast naturally, you can save fuel and maintain a smoother driving experience.

Keeping the revs in a flat line is also crucial for your fuel economy, and cruise control lets you drive at a steady RPM rate. You’ll save much more fuel this way since any fluctuations in gear changes and revs consume more fuel. For instance, revving your car and keeping the engine spinning at high RPMs will only burn more fuel. On the other hand, if you drive at a lower RPM level, the engine will burn less fuel, especially in a longer drive. That’s why the cruise control setup can kick in quite well in helping you waste less fuel while driving on the highway. This is even true when operating a vehicle that possesses adaptive cruise control.
