Does cruise control save gas? Does using cruise control improve or decrease gas mileage? Does using the air conditioner or opening windows use more gas? Are those fuel line magnets and tornado devices for the intake and exhaust pipes functional? Let’s explore these issues in depth because, regardless of the price of gas, we owe it to Mother Earth to do everything in our power to travel as far as we can on the least amount of gas possible. 

How Is Cruise Control Used?

Various cruise control models with varying degrees of adaptability are available on the market today. To use cruise control in its most basic configuration, the driver must first reach a certain speed before turning it on.

Another, more sophisticated system called “adaptive cruise control” uses cameras and/or sensors to change the speed of the car in order to maintain a safe distance from other vehicles. In some circumstances, the vehicle can even change lanes and automatically abide by traffic signals.

The dual purpose of these systems is to increase fuel efficiency while also ensuring the safety of the passengers inside the vehicle. No matter how sophisticated your car’s computer is, in many cases your human brain is still better equipped to make those decisions.

Does Cruise Control Save Gas?

Yes, cruise control can help you save on gas. Cruise control is advantageous for your car and not just for fuel efficiency. When you use cruise control, acceleration and braking are reduced, which protects your car from wear and tear caused by frequent acceleration and braking. When used on flat terrain and during gradual uphill or downhill climbs, cruise control is most useful.

Whether cruise control reduces gas consumption was tested by Edmunds. They came to the conclusion that it does save gas and discovered that an average of 7% can result in savings of up to 14%. Since the driver is not accelerating or braking, cruise control smoothes out the drive and stops the vehicle’s RPMs from jitterily surging, claims Edmunds.

It’s crucial to remember that there is a recommended break-in period when you shouldn’t use cruise control in new cars. According to manufacturer, we’ve divided up the break-in mileage as follows:

  • GM: 500 miles
  • Hyundai: 600 miles
  • Volkswagen: 1000 miles
  • Ford: 1000 miles
  • Kia: 600 miles
  • Genesis: 600 miles
  • Ram: 300 miles

How Much Fuel Does Cruise Control Save?

Your ankle feels jerky. According to a Natural Resources Canada study, driving at 80 kph (49.7 mph) on the cruise control instead of cycling between 75 and 85 kph (46.6 to 52.8 mph) every 18 seconds uses 20% less fuel and significantly lessens motion sickness. More modest claims in single-digit percentages are cited in studies by CNN/Money and others.

The Benefits Of Cruise Control

On highways with constant speed, cruise control is useful. It is ideal for similarly leveled roads where you do not need to downshift. However, the majority of contemporary vehicles today will automatically change the gears and rpm for you. Using cruise control has many benefits, including increased comfort and productivity. If cruise control is an option while driving on the freeway, using it is more convenient because you can just cruise along.

As you set your speed, cruise control helps you avoid exceeding the limit. To accomplish this, set your cruise control to the desired speed and accelerate manually to that speed. Depending on the car you drive, this varies. You can maintain the right speed thanks to this. Additionally, you can typically adjust the set speed incrementally by using the cruise control features on your car.

A comfort-enhancing feature is cruise control. Give your feet and legs a break if you can while driving a long distance. If the road is clear, you can rest your legs by using the cruise control.

Your fuel economy and gas mileage will both greatly benefit from using cruise control. In contrast to cruise control, which can keep this at a constant optimal level and consequently requires less gas to maintain the desired speed, pressing down on the gas pedal will naturally result in you using more gas to accelerate and constantly adjust your speed. Your fuel economy will increase because using cruise control prevents you from consuming more fuel than necessary. 

Negatives Of Cruise Control

When used without manual control, cruise control can have some detrimental effects, including the risk of fatigued drivers and potential distractions. You might be more likely to concentrate on other aspects of driving or even use your smartphone when you are not pressing the gas pedal. Although using cruise control may make it seem like it’s simpler to multitask, this is not safe and you should be aware of it.

This is a bad idea, and it’s crucial to keep in mind when utilizing cruise control. Using cruise control does help you relax a little bit because you don’t have to worry about maintaining the speed yourself, but driving will still exhaust you, so make sure to take appropriate breaks on long distances as you start to feel fatigued. Driving when you’re tired, especially at night, feels grueling and hard work in and of itself.

Additionally, it could be argued that driving becomes less mentally stimulating because you aren’t actively controlling the speed of the vehicle with your feet. The result could be a slower reaction time when emergency braking is necessary or a general lack of awareness.

Cruise Control

Does Your Car Need Cruise Control?

The driveline is harmed by acceleration, which wastes fuel, so cruise control is beneficial for the vehicle. BIG CAVEAT: Cruise control should not be used in heavy rain, snow, or at temperatures where ice could form, because any acceleration on slick surfaces or while hydroplaning can induce an under- or oversteer event, and/or a resulting stab at the brake pedal to unset the cruise control can result in loss of control and an accident.

Does Your Engine Suffer From Cruise Control?

It’s actually better for your engine to use cruise control than not. Because manual acceleration increases engine engagement, reducing it helps your engine. By maintaining a constant speed, it spares your engine work. Because it is much gentler than human input, cruise control.

The Transmission Is Damaged By Cruise Control.

The transmission or engine of your car won’t be harmed by cruise control in newer models. The system will function with the transmission and engine if the car has cruise control that was installed at the factory. By doing this, overheating or overspeeding will be prevented.

The clutch switch’s improper installation is the only potential risk. The cruise control should disengage once you depress the clutch. The engine and transmission could be overwhelmed by the cruise control system if the clutch switch is not functioning properly. 

Do I Need To Always Drive In Cruise Control?

It is not necessary to use cruise control constantly, despite the fact that it is convenient and good for your engine. Cruise control, for instance, is useless in traffic. This is brought on by the constant stopping and starting. However, this doesn’t apply if the vehicle is more recent and has adaptive cruise control, which does this for you automatically.

On roads with uncertain terrain and hills, for instance, cruise control is not helpful. Depending on the gear your car is in, the cruise control might not work very well, and you might need to brake for corners and slow down. Using cruise control will require more effort from you, and it won’t function as effectively. 

When Should You Put The Cruise Control On To Save Gas?

Sean Cooper of Car Buying and Selling says cruise control only saves gas when it’s lowering the workload of your vehicle. Your car will use more gas every time you ask it to accelerate. 

On open highway stretches, for example, if you can drive at a certain speed for an extended period of time, you can reduce workload while also reducing fuel consumption. The speed maintenance feature of the cruise control can do this more precisely than your foot.

Contrarily, no matter how sophisticated your cruise control system is, if you’re in a city or stuck in traffic, your fully alert brain is much better at reducing the strain on your engine. There are restrictions on even systems like Tesla’s “Full Self-Driving.” 

The more decisions that need to be made, the more likely you are to be the best candidate for making them. If you’re still unsure when to use cruise control, keep this idea in mind.

Does Air Conditioning Use More Gas Than Open Windows?

The engineer’s explanation is that since the energy needed to overcome aerodynamic drag varies with the cube of the vehicle’s speed, each vehicle will have a specific speed at which opening the windows will result in more drag and energy use than running the air conditioner’s compressor. It’s usually best to roll down the windows at city speeds and run the air at highway speeds in older, less aerodynamic vehicles with rudimentary A/C systems. However, modern vehicles come equipped with extremely effective climate control systems that make use of variable-output compressors, humidity sensors, and in some cases, heat-pump technology. Additionally, the aerodynamics of newer cars are frequently more compromised when the windows are opened. Therefore, even the most ardent environmentalists shouldn’t feel bad about riding in comfortable climate control if they’re driving a modern vehicle.

Other Methods To Save Gas Consumption

  • Driving conservatively instead of aggressively
  • Driving the speed limit
  • Avoiding long periods that the vehicle is idling in
